Version 14.5.0 — on par with Mem0 Platform on LoCoMo and LongMemEval

Release date: 2026-09-23.

Mem0 publishes the per-question answers behind its LoCoMo and LongMemEval figures. We graded them and TAM's answers to the same held-out questions with the same judge model and two judge prompts — the one the public numbers used and Mem0's current one (report and how to reproduce it):

Held-out questions, accuracy % LoCoMo (1,144), published judge LoCoMo, Mem0 judge LongMemEval-S (400), official judge LongMemEval-S, Mem0 judge
Mem0 Platform (gpt-5 answering, top 200 memories) 88.46 94.32 91.00 91.75
TAM (gpt-5 answering) 86.54¹ 94.23 92.25 90.75
TAM (gpt-4.1-mini answering) 88.02¹ 94.32¹ 87.50 88.25

¹ English embedding preset (MEMORY_TEXT_EMBED_MODEL=BAAI/bge-base-en-v1.5); with the default multilingual model, 87.50 and 92.57. No difference between TAM and Mem0 Platform at the same answering model is statistically significant — a tie, with TAM retrieving locally and calling no LLM when it writes or searches. The report also lists how Mem0's published setup differs from the earlier public protocol: a more lenient judge, 156 re-run questions, and answer-prompt hints that match individual LoCoMo gold answers.

What changed:

Change How you use it
Cross-encoder reads the neighbouring turns Automatic. Each candidate is scored alone and with the turns before and after it; MEMORY_CROSS_RERANK_CONTEXT (400 characters, 0 = off).
Relative dates resolved in context mode Automatic. "last Thursday [Thu 14 December 2023]", counted from the record's timestamp; MEMORY_CONTEXT_RESOLVE_DATES=off disables it.
Context budget shared by rank Automatic. The first hits keep long records whole; answers about something the assistant said reach the reader whole for every development question instead of 38%.
MEMORY_TEXT_EMBED_MODEL works; models above 2 GB load Set it to change the model of ordinary records (re-embed with python src/reembed.py --fastembed).
Head-to-head tooling benchmarks/crossgrade_mem0.py, benchmarks/retrieval_eval.py; the QA harnesses take reasoning models (--answer-model gpt-5-2025-08-07).

Version 14.4.0 — opt-in fact supersession, cheaper writes at 1M records

Release date: 2026-09-22.

A record can now retire the value it replaces. memory_save(supersede=true) looks for active records of the same project and type that share the new record's opening words and end in a different value ("X's citizenship is Argentina" → "... is Armenia", "billing runs on PostgreSQL 16" → "18"), marks them superseded and returns their ids. It is off by default: on a real 5,128-record store the rule would have retired 138 records that were not updates, such as "likes jazz" next to "likes rock". On MemoryAgentBench FactConsolidation with gpt-4o-mini (findings):

14.3.1 14.4.0, supersede=true
FC single-hop, 6k / 262k 82 / 85 99 / 93
FC multi-hop, 6k / 262k 13 / 3 27 / 9

What changed, including two write-side costs that grew with the store:

Change How you use it
Fact supersession memory_save(..., supersede=true) or memory_save_fast(..., supersede=true) for single-valued facts. The response lists retired ids under superseded.
Vector cache patches instead of reloading Automatic. Migration 036 logs which record each change touched; a cached pool re-reads only those rows when a search next uses it. Unscoped recall right after a save at 1M records: 4.2 s → 0.37 s.
Concept name refresh uses an index Automatic. Migration 037 indexes graph node names that can match text; the 60-second refresh that stalled one save a minute takes 2.6 ms. Save p99 at 1M records: 1,432 → 140 ms (report).

Version 14.3.1 — updates are no longer dropped, recall stays fast at 1M records

Release date: 2026-09-21.

Two problems that got worse as a store grew. Dedup treated near-identical texts as repeats, so an update that changed one value ("Messi's citizenship is Argentina" → "... Armenia", "PostgreSQL 16" → "18") was dropped and the old value kept; on MemoryAgentBench FactConsolidation 14.3.0 lost 36 of 455 facts. And several queries behind every recall and save read the whole store. Measured on one machine with 200 synthetic tenants (report):

14.3.0 14.3.1
Tenant-scoped memory_recall, 100k records, p50 / p95 781 / 1,901 ms 25 / 35 ms
Tenant-scoped memory_recall, 1M records, p50 / p95 6–64 s 105 / 147 ms
HTTP calls/s, 100k records, 16 clients 1.3 37 (one process), 117 (MCP_HTTP_WORKERS=4)
Change How you use it
Updates are kept Automatic. A record is a repeat only when it has the same words in the same order (case, punctuation and ё/е aside). A repeat replaces the stored record, so "A", then "B", then "A" leaves A as the latest.
Scoped search follows the project, not the store Automatic. Migration 035 puts the project into the full-text index (rebuilt once, about 30 s per million records); graph seeds and available_solutions use indexes.
HTTP workers MCP_HTTP_WORKERS=4 with MCP_TRANSPORT=http: four server processes on one port, stateless sessions, POSIX only. In Docker Compose: TAM_MCP_WORKERS=4.
Scale benchmark benchmarks/scale_bench.py loads a synthetic multi-tenant corpus through the real save path and measures recall, save, HTTP throughput and concurrent writers.
MemoryAgentBench FactConsolidation results: findings.

Version 14.3.0 — Jev as the contradiction checker

Release date: 2026-09-21.

memory_answer can now check retrieved facts for contradictions with TypeSafe's Jev, a System One model that answers typed questions with calibrated probabilities instead of generating text. Every (supporting, opposing) pair becomes one noul question, and all of them go in a single request. Measured on the same questions against the Claude Haiku 4.5 scorer (report): accuracy is unchanged within noise (LongMemEval knowledge-update 35/78 vs 36/78, control 15/50 vs 16/50). The median contradiction pass drops from 3.1 s to 1.9 s, and Jev billed $0.038 for all 78 questions.

Change How you use it
Jev contradiction scorer MEMORY_CONTRADICTION_SCORER=jev plus TYPESAFE_API_KEY. The default stays llm. The client retries 408, 429, 5xx and connection errors like the official SDKs, honours retry-after-ms / Retry-After up to 60 s, and reports jev_* counters and a jev_request_ms latency histogram.
API key hygiene An empty key, or one containing a newline or other control character, is rejected before any request, and the error never contains the key. (The official Python and JS SDKs echo it; reported upstream as typesafe-sdk-python#9 and typesafe-sdk-js#14.)
Benchmark harness benchmarks/knowledge_update_eval.py records per-question contradiction-pass time and Jev token usage, so the two scorers can be compared on cost as well as accuracy.

Version 14.2.0 — facts that change over time

Release date: 2026-09-21.

"Mary loves red", saved in May, and "Mary no longer likes red; she has fallen for green", saved in August: memory_answer now says green, previously red. Measured with Claude Haiku 4.5 on the same questions (report): LongMemEval knowledge-update rose from 12/78 to 35/78, a Russian + English update suite from 8/30 to 22/30, and five other LongMemEval categories from 11/50 to 16/50.

Change How you use it
Recording dates reach the reader memory_answer's reader and verifier see when each record was saved. The latest record about the same subject gives the current value unless its text describes the past, and a value stays current until a later record changes it. Answers come back in the language of the question.
Contradictions are resolved, not refused A hard contradiction now passes both sides, with their dates, to the reader. MEMORY_CONTRADICTION_POLICY=abstain restores the 14.1.0 refusal. The contradiction scorer sees the question, so a conflict about someone else no longer blocks the answer.
Russian word forms The lexical recall tier stems Cyrillic terms (Snowball, new dependency snowballstemmer): "Маша" in a question finds "Маше" in a record, and claim grounding accepts the inflected name.
One timestamp format Records are stored as 2026-09-21T08:21:37.622445Z (UTC). Migration 034 rewrites older rows: +00:00 and fraction-less values are reformatted, and zone-less values, which older versions wrote in local time, are converted with that zone's DST rules. The instants do not change, so atomic facts are not rebuilt.

Version 14.1.0 — what is new

Release date: 2026-09-21.

Change How you use it
Negative retrieval in memory_answer Before reading, the grounded reader runs a second, contradiction-seeking search: a small model inverts the question, and each (supporting, opposing) pair — at most 5 × 5 — is scored in one batched call. Score ≥ 0.60 answers Not enough information without picking a side; 0.30–0.60 answers with a caveat; below 0.30 the answer is unchanged. The verdict is returned under negative. MEMORY_NEGATIVE_RETRIEVAL=false turns it off.
memory_answer on Anthropic and Ollama Both providers now return schema-constrained output (forced tool call / JSON-schema format). Before this, Claude Haiku wrapped JSON in a markdown fence and memory_answer failed with Reader returned invalid grounded evidence.

Version 14.0.0 — what is new

Release date: 2026-09-15 · Status: release candidate; registry publication pending. Use the prepared wheel or this source checkout for v14. The general package-manager commands below follow their published channels and do not guarantee v14 before publication.

Change How you use it
Personal, team and shared memory Install one server; give Vasya and Petya separate tokens. Select a scope when saving; search all areas you can access. Each area has its own database, graph and index.
Authorship and revision history The token identifies the author and client. See who changed a record, when and why; revision checks prevent overwriting another person's edit.
Remote MCP and team web interface Connect an IDE through the lightweight Python bridge. In the browser, select a scope, search, browse, save, edit and inspect history. The interface displays the product name, version and release date.
Lower CPU pressure Fast mode remains the default. Embedding and optional PyTorch models default to one compute thread. The team server retains three workspace workers to avoid repeated model loading.
Configurable internal LLMs Use Ollama, an OpenAI-compatible endpoint or Anthropic for internal text tasks; explicitly select a vision model for images.
Safer retrieval and answers Scoped context, model-aware vector search and privacy-safe write intents. The optional grounded reader checks supporting evidence and rejects contradictory claims; it is not the default answer path.
Installation and packaging fixes Wheel, source archive and Docker checks cover Linux, Windows and macOS; the source archive now includes test fixtures and installation support files.

Validation: 2,162 tests passed in the checkout; 2,145 passed from the source archive. Native wheel checks passed on Ubuntu, Windows and macOS; 12 browser scenarios passed across Chromium, Firefox and WebKit. The expanded CI matrix still requires execution. See the final verification report for skips, exact platforms and artifact hashes.

Performance limits: BGE is optional. On the measured Linux ARM64 setup, its one-thread p95 was about 2,179 ms, above the 200 ms target. Limiting threads reduces parallel CPU load; it does not eliminate CPU work. No top-10 ranking or new default answer-quality improvement is claimed. CPU measurements.

Full v14 release notes · Changelog and previous releases

Getting started with v14

Choose local or server mode

Mode Install and use
Local, one person Follow native or Docker installation, then Quick start. Memory and models run on your machine; the local MCP catalogue has 74 tools.
Server, multiple people Follow the setup below. Memory and models run on the server; clients need only Python and their token. The remote catalogue exposes eight core tools.

The server instructions work with the prepared v14 wheel on Linux, macOS and Windows. Run commands in a directory where you can create the data folder and token files.

Start a server without Docker

Install the candidate wheel in a dedicated environment. Linux/macOS:

python3 -m venv .venv
. .venv/bin/activate
python -m pip install ./dist/total_agent_memory-14.5.1-py3-none-any.whl

Windows PowerShell, using the environment directly without changing the execution policy:

py -3 -m venv .venv
.\.venv\Scripts\python.exe -m pip install .\dist\total_agent_memory-14.5.1-py3-none-any.whl
$env:PATH = "$PWD\.venv\Scripts;$env:PATH"

Then, on any of these systems:

tam-team --root ./team-data user-add vasya 'Vasya'
tam-team --root ./team-data user-add petya 'Petya'
tam-team --root ./team-data team-add engineering 'Engineering'
tam-team --root ./team-data member vasya engineering editor
tam-team --root ./team-data member petya engineering editor
tam-team --root ./team-data token-create vasya --client codex --out ./vasya.token
tam-team --root ./team-data token-create petya --client cursor --out ./petya.token
tam-team --root ./team-data serve --host 127.0.0.1 --port 3738

Open http://127.0.0.1:3738/ and sign in with the contents of your token file. Keep each token private; give Petya his own token, not Vasya's. For access from other machines, configure an HTTPS reverse proxy to the server's /mcp/ endpoint and web interface. Permissions, backup, restore and server configuration.

Start a server with Docker Compose

From this checkout, with port 3738 available:

docker compose -f docker-compose.team.yml build
docker compose -f docker-compose.team.yml run --rm team-memory python /app/src/team_memory/cli.py user-add vasya 'Vasya'
docker compose -f docker-compose.team.yml run --rm team-memory python /app/src/team_memory/cli.py token-create vasya --client codex --out /team-data/vasya.token
docker compose -f docker-compose.team.yml up -d
docker compose -f docker-compose.team.yml cp team-memory:/team-data/vasya.token ./vasya.token

The web interface is at http://127.0.0.1:3738/. The token copied to the host is a credential: restrict file access to its owner. To add Petya, a team and membership, use the same CLI subcommands shown above through docker compose -f docker-compose.team.yml run --rm team-memory python /app/src/team_memory/cli.py.

Compose keeps data and model caches in persistent volumes. Set TAM_TEAM_PORT, TAM_TEAM_MAX_WORKERS and LLM settings in .env as needed; see .env.example. Plan at least 4 GiB RAM for three warm MiniLM workers and measure your own workload. Docker server details.

Connect a remote IDE

Copy src/team_memory/remote.py to the client and supply its personal token file. This bridge uses only the Python standard library. For clients with an mcpServers configuration:

{
  "mcpServers": {
    "total-agent-memory": {
      "command": "python3",
      "args": ["/absolute/path/remote.py"],
      "env": {
        "TAM_REMOTE_URL": "https://YOUR_SERVER/mcp/",
        "TAM_REMOTE_TOKEN_FILE": "/absolute/path/vasya.token"
      }
    }
  }
}

Replace the paths and server address. On Windows use the path to python.exe and Windows file paths. Local testing may use http://127.0.0.1:3738/mcp/; remote connections require HTTPS. If the package is installed on the client, tam-remote is also available. Client configuration details.

Save, search and see who changed what

Ask your agent to call memory_scopes first to list available areas. These are example arguments for the remote memory_save tool:

{"content":"My investigation notes", "scope":{"kind":"personal"}, "tags":["release-v14"]}
{"content":"Engineering release checklist", "scope":{"kind":"team","team_id":"engineering"}, "tags":["release-v14"]}
{"content":"Company-wide onboarding guide", "scope":{"kind":"shared"}, "tags":["onboarding"]}
  • Personal: visible only to the token's owner; this is the default for saves.
  • Team: visible to members; reader can read, editor can also change records.
  • Shared: readable and editable by every authenticated user of this server.
  • Tags: organize topics. Access comes from scope and membership; reserved scope:, team: and user: tags are managed by the server.

Call memory_recall with {"query":"release checklist"} to search all accessible areas, or add a scope to narrow the search. Use memory_get and memory_history with the returned record's id and scope to inspect content, author and changes. memory_update requires those fields plus expected_revision, content and reason; use the new ID returned by the update for subsequent operations. The author is taken from the token automatically.

The remote tools are memory_scopes, memory_save, memory_recall, memory_get, memory_update, memory_delete, memory_history and memory_export. History and export are paginated. Full behavior and retry rules.

Configure internal models and CPU

Fast mode works without an LLM. To use a local model for optional internal tasks, set these environment variables (or .env for Compose):

MEMORY_LLM_ENABLED=true
MEMORY_LLM_PROVIDER=ollama
MEMORY_LLM_MODEL=YOUR_INSTALLED_MODEL
OLLAMA_URL=http://127.0.0.1:11434
MEMORY_EMBED_THREADS=1
MEMORY_TORCH_THREADS=1

For Docker, the Ollama address must be reachable from the container; the team profile defaults to http://host.docker.internal:11434. For another compatible server, select MEMORY_LLM_PROVIDER=openai-compatible and set MEMORY_LLM_API_BASE, MEMORY_LLM_MODEL and, if required, MEMORY_LLM_API_KEY. Compatibility means Chat Completions, with JSON Schema support for structured tasks. Set MEMORY_VISION_MODEL separately for images. Restart after changing environment settings. Provider settings and CPU limits.

Optional remote LLM providers receive the content used in those tasks. Keep Ollama local or set MEMORY_LLM_ENABLED=false if that content must stay on your own infrastructure.

Table of contents

The problem it solves

AI coding agents have amnesia. Every new Claude Code / Codex / Cursor session starts from zero. Yesterday's architectural decisions, bug fixes, stack choices, and hard-won lessons vanish the moment you close the terminal. You re-explain the same things, re-discover the same solutions, paste the same context into every new chat.

total-agent-memory gives the agent a persistent brain — on your machine, not in someone else's cloud.

Every decision, solution, error, fact, file change, and session summary is:

  • Captured — explicitly via memory_save or implicitly via hooks on file edits / bash errors / session end
  • Linked — automatically extracted into a knowledge graph (entities, relations, temporal facts)
  • Searchable — 6-stage hybrid retrieval (BM25 + dense + graph + CrossEncoder + MMR + RRF fusion), 95.1% R@5 on public LongMemEval
  • Private by default — SQLite + FastEmbed + optional local Ollama. In server mode, memory stays on your server; external LLMs receive content only when configured and used.

60-second demo

You:     "remember we picked pgvector over ChromaDB because of multi-tenant RLS"
Claude:  ✓ memory_save(type=decision, content="Chose pgvector over ChromaDB",
                       context="WHY: single Postgres, per-tenant RLS")

[3 days later, different session, possibly different project directory:]

You:     "why did we pick pgvector again?"
Claude:  ✓ memory_recall(query="vector database choice")
         → "Chose pgvector over ChromaDB for multi-tenant RLS. Single DB
            instance, row-level security per tenant."

It's not just retrieval. It's procedural too:

You:     "migrate auth middleware to JWT-only session tokens"
Claude:  ✓ workflow_predict(task_description="migrate auth middleware...")
         → confidence 0.82, predicted steps:
             1. read src/auth/middleware.go + tests
             2. update session fixtures in tests/
             3. run migration 0042
             4. regenerate OpenAPI spec
           similar past: wf#118 (success), wf#93 (success)

Benchmarks — how it compares

Everything below is retrieval: does the memory surface the passage that contains the answer, in the top-K? That is the part this project owns — answer quality is bounded above by it, and it can be graded with no LLM in the loop, which makes the numbers deterministic, free, and reproducible on your machine.

Two things to read them honestly:

  • These are the default fast profile — FastEmbed, no reranker, no LLM anywhere in the path. That is what you get after install.sh, not a tuned configuration.
  • Every runner passes record_usage=False. Recall.search normally bumps recall_count, and the scorer adds recall_boost = min(0.3, recall_count × 0.05) — so before v13, each re-run against the same database scored higher than the last, partly measuring its own history. A clean run and a re-run are now byte-identical.

BEAM — Beyond a Million Tokens, ICLR 2026

BEAM is the benchmark that starts where context windows stop: conversations of 100K / 500K / 1M tokens (a separate 10M set goes further), probed across ten distinct memory abilities. Scored here against each probe's source_chat_ids.

Latency p50 17.7 ms. The shape is the useful part: contradiction resolution, temporal reasoning and knowledge update are effectively solved, while instruction_following and event_ordering are near-zero — those probes ask whether a stated instruction was followed or in what order things happened, and semantic similarity to the question does not find the message where the instruction was given. Retrieval is the wrong primitive there, and that is the roadmap item.

Recall decays gracefully — 13× the haystack costs 12.7 points of R@5, and the abilities that hold up (knowledge update, contradiction resolution) hold up at every scale. The two curves that do not decay gracefully are the interesting part, and they have separate causes.

Ingest — found and fixed. Throughput fell 5× across the three scales on identical code. The cause was ours: graph/auto_link.py runs on every save and constructed a fresh ConceptExtractor each time. The node-name cache lives on the instance, so it was thrown away immediately and the whole graph_nodes table was re-read per write — 1,000 saves triggered 1,000 full table reads (~139 million rows at the 139k nodes this ingest reaches). Fixed in v13.0.1; counting reads rather than timing makes the check load-independent, and it is now 1 read per 1,000 saves. The ingest column above was measured before that fix and is kept as the record of the problem.

Search — open. p50 grew 7× between 500K and 1M for 2× the data. Store._binary_search loads the binary vectors of every active record into numpy on each query, so search is linear in store size. That is a different problem from the ingest one and is not fixed; an ANN index over the binary vectors is the obvious answer and has not been built yet. Stated rather than buried, because 411 ms is a real number a user would feel.

LongMemEval — xiaowu0162/longmemeval-cleaned

470 questions across six question types, re-measured for v13 through the product: each question's haystack is ingested into a real Store and queried with Recall.search, the same path an agent takes.

Question type Count R@5 (recall_any)
knowledge-update 72 100.0%
multi-session 121 98.3%
single-session-user 64 95.3%
single-session-assistant 56 94.6%
temporal-reasoning 127 92.9%
single-session-preference 30 80.0%
total 470 95.1%

Also recall_all@5 85.7% (every required fragment, not just one), NDCG@5 88.9%, 27.6 ms per query.

This replaces the 96.2% we published before, and the difference matters more than the 1.1 points. Until v13 this runner used its own self-contained BM25 / RRF / MMR / CrossEncoder stack, so the number described an algorithm, not this software. --modes store drives the shipping path and is now the default. The old modes remain for ablations.

For reference on the same set, Mastra "Observational" reports 95.0% and Supermemory 85.4% — both cloud services.

On end-to-end accuracy numbers

Systems in this space usually publish LoCoMo accuracy — a generator answers from the retrieved context and an LLM judges it. We publish it too, with the two caveats that make it meaningful.

One LLM-judged run is a sample, not a measurement. Temperature 0 does not make the API deterministic and OpenAI documents seed as best-effort, so the runner takes --seed and we report three runs:

Category N mean min max spread
single-hop 282 0.366 0.358 0.372 0.014
temporal 321 0.426 0.424 0.427 0.003
multi-hop 96 0.292 0.281 0.302 0.021
open-domain 841 0.570 0.567 0.573 0.006
adversarial 446 0.904 0.899 0.908 0.009
overall (no adversarial) 1,540 0.486 ± 0.002 0.484 0.488 0.005
overall (all) 1,986 0.579 ± 0.002 0.578 0.582 0.004

gpt-4o generator, gpt-4o-mini judge, seeds 1/2/3. Retrieval was byte-identical across all three — only generation and judging vary.

The judge needed two guards, and they point opposite ways.

Refusals scored as correct answers. On ~100 of the 1,540 non-adversarial questions per run, the judge answered YES to "Not mentioned in the conversation." against golds like Sweden, June 2023, Single — F1 exactly 0.00. Almost certainly the adversarial rule bleeding across, since the judge is told to accept a refusal when the gold also indicates no information. Per category the inflation runs 3.2 pp (open-domain) to 14.3 pp (temporal).

Hallucinations scored as correct abstentions. 99.6% of LoCoMo's adversarial golds are the empty string. The judge accepts almost any fluent answer against an empty reference, so 27–30 invented answers per run scored correct — inflating the one category we used to lead on.

Both are rules rather than judgements — on categories 1–4 the gold is a fact, so a refusal cannot be right; with an empty gold, only a refusal can be — so both now run deterministically at judging time. Effect: no-adv 0.551 → 0.486, adversarial 0.966 → 0.904, all 0.645 → 0.579. The table above is corrected.

How noisy is the rest? Aligning all 1,986 questions across the three seeds:

share
generator's answer differed between seeds 12.5%
judge's verdict differed 5.1%
judge flipped on an identical answer 2.7%

The aggregate holds within ±0.005 because those flips roughly cancel, not because the instrument is precise. Quoting one run to three decimals — as we did before — is not supported by the data.

Not comparable to the 90%+ figures some competitors publish: different generators, judges, prompts and question subsets. And on this evidence, an unguarded LLM judge can be worth six points on its own. The retrieval numbers above remain our primary metric because they are checkable without an API key.

Do the retrieval numbers mean anything? — negative controls

A retrieval score with no floor under it is not a claim. Every LoCoMo run now scores three degenerate baselines on the same questions:

Baseline R@1 R@5 R@10
random — ten turns from the same conversation 0.001 0.012 0.023
first — the ten earliest turns 0.000 0.023 0.039
recency — the ten most recent turns 0.001 0.003 0.011
the pipeline 0.331 0.607 0.687

27× the best degenerate baseline. The controls run in the same pass as the metric, so the floor ships with the number rather than living in a script somebody stops running.

On competitors' benchmark numbers. mem0 publishes 92.5 on LoCoMo and 94.4 on LongMemEval, from its managed platform with gpt-5 answering and judging. It also publishes the answers behind them, so they can be graded next to TAM's under one judge: on the same held-out questions the two systems tie on both benchmarks (head-to-head). Where a project has not published per-question answers, we do not compare against its number.

What you get

Eight capabilities nobody else ships

Capability Tool One-liner
🧠 Procedural memory workflow_predict / workflow_track "How did I solve this last time?" — predicts steps with confidence
🔗 Cross-project analogy analogize "Was there something like this in another repo?" — Jaccard + Dempster-Shafer
⚠️ Pre-edit risk warnings file_context Surfaces past errors / hot spots on the file you're about to edit
🛡 Self-improving rules learn_error + self_rules_context Bash failures → patterns → auto-consolidated behavioral rules at N≥3
🕰 Temporal facts kg_add_fact / kg_at Append-only KG with valid_from/valid_to — query what was true at any point
🎯 Task workflow phases classify_task / phase_transition Automatic L1-L4 complexity classification, state machine across van/plan/creative/build/reflect/archive
🧩 Structured decisions save_decision Options + criteria matrix + rationale + discarded → searchable decision records with per-criterion embeddings

Plus the basics done well

  • 6-stage hybrid retrieval (BM25 + dense + fuzzy + graph + CrossEncoder + MMR, RRF fusion) — 95.1% R@5 public
  • Multi-representation embeddings — each record embedded as raw + summary + keywords + questions + compressed
  • AST codebase ingest — tree-sitter across 9 languages (Python, TS/JS, Go, Rust, Java, C/C++, Ruby, C#)
  • Auto-reflection pipeline — memory_save → LaunchAgent file-watch → graph edges appear ~30 s later
  • rtk-style content filters — strip noise from pytest / cargo / git / docker logs while preserving URLs, paths, code
  • 3D WebGL knowledge graph viewer — 3,500+ nodes, 120,000+ edges, click-to-focus, filters
  • Hive plot & adjacency matrix — alternate graph views sorted by node type
  • A2A protocol — memory shared between multiple agents (backend + frontend + mobile in a team)
  • design-explore skill — drop-in Claude Code skill that walks L3-L4 tasks through options → criteria matrix → save_decision before code (see examples/skills/design-explore/SKILL.md)
  • <private>...</private> inline redaction in any saved content
  • Cloud LLM/embed providers with per-phase routing (OpenAI / Anthropic / OpenRouter / Together / Groq / Cohere / any OpenAI-compat)
  • activeContext.md Obsidian projection for human-readable session state
  • Phase-scoped rules (self_rules_context(phase="build")) — ~70% token reduction

Install

Quickstart — pick one

These are the published distribution channels. For the unpublished v14 candidate, use the wheel or source-based Compose instructions above.

Channel Command What it does
npx (Node) npx -y total-agent-memory connect claude-code Zero-install. Bootstraps a Python venv in ~/.tam/.venv via uv (or python3 fallback), pulls the PyPI server, wires the MCP entry into your IDE. Replace claude-code with codex / cursor / cline / continue / aider / windsurf / gemini-cli / opencode.
uvx (Python via uv) uvx total-agent-memory One-off run with no install. Best for trying without commitment.
pipx (Python isolated) pipx install total-agent-memory Installs the total-agent-memory, tam, tam-lookup, lookup-memory binaries on PATH in an isolated venv.
brew (macOS / Linuxbrew) brew install vbcherepanov/tap/total-memory Bottle-style install with tam and legacy claude-total-memory symlinks.
Docker (multi-arch) docker run -p 37737:37737 -v ~/.tam:/data ghcr.io/vbcherepanov/total-agent-memory:14.5.1 Containerized (linux/amd64 + linux/arm64). Dashboard on :37737.
Claude Code plugin /plugin marketplace add vbcherepanov/total-agent-memory
/plugin install total-agent-memory@vbcherepanov		 Installs the MCP server, the memory-protocol skill and all seven capture hooks in one step, from inside Claude Code. The bootstrap reuses an existing install if it finds one, so nothing is downloaded twice.
Manual clone git clone https://github.com/vbcherepanov/total-agent-memory ~/total-agent-memory && cd ~/total-agent-memory && ./install.sh --ide claude-code Full control. Lets you hack on the server, run benchmarks, and pick which background services to enable. Detailed walkthrough below.

All seven channels land at the same MCP server. The npx and ./install.sh paths additionally configure IDE-specific MCP entries and hooks. Other channels start the server bare — you wire the IDE afterwards (see docs/installation.md).

The reranker is an extra, not a dependency. A base install is 97 packages and ~113 MB of wheels: fastembed runs the embeddings through ONNX and no torch is resolved anywhere. The CrossEncoder / BGE reranker needs the torch stack, which on Linux drags in the whole nvidia-cu* set — 147 packages and ~3.1 GB — so it ships separately, and the default MEMORY_MODE=fast does not use it. Turn it on with MEMORY_MODE=deep (or MEMORY_RERANK_ENABLED=true) and install it:

pip install "total-agent-memory[rerank]"      # pip / uvx / pipx
pip install -r requirements-rerank.txt        # clone / Docker

Upgrade from v11.x? Whatever channel you pick will auto-migrate ~/.claude-memory/ → ~/.tam/ on first run and keep a symlink for backward compat. No manual data move required.

Detailed paths (manual / Docker / per-IDE)

Two manual paths. Same 74 tools, same dashboard, different deployment shapes.

IDE matrix (v10.5)

The same MCP server, same tools, same protocol — different installation locations and hook wiring per IDE. The installer (install.sh --ide <name>) automates all of it.

Platform matrix

OS Command Background services
macOS 10.15+ ./install.sh --ide claude-code LaunchAgents (launchctl)
Linux (Ubuntu 22.04+, Debian 12+, Fedora 38+) ./install.sh --ide claude-code systemd --user
WSL2 (Windows 11 + Ubuntu/Debian) ./install.sh --ide claude-code systemd --user — requires /etc/wsl.conf with [boot] systemd=true; otherwise falls back to shell-loop autostart
Windows 10/11 native .\install.ps1 -Ide claude-code Task Scheduler

Full per-platform walkthrough, WSL2 Windows-host-vs-WSL IDE nuances, the wsl -e MCP-command pattern, IDE coverage matrix, and uninstall/diagnostic flows: docs/installation.md.

Path A — native (macOS / Linux / WSL2)

git clone https://github.com/vbcherepanov/total-agent-memory.git ~/total-agent-memory
cd ~/total-agent-memory
bash install.sh --ide claude-code   # or: cursor | gemini-cli | opencode | codex

The installer:

  1. Clones + creates ~/total-agent-memory/.venv/
  2. Installs deps from requirements.txt and requirements-dev.txt
  3. Pre-downloads the FastEmbed multilingual MiniLM model
  4. Registers the MCP server via claude mcp add-json memory ... (stored in ~/.claude.json, the canonical store Claude Code actually reads)
  5. Copies all hooks (session-*, user-prompt-submit.sh, post-tool-use.sh, pre-edit.sh, on-bash-error.sh, etc.) into ~/.claude/hooks/ and registers them in ~/.claude/settings.json
  6. Grants permissions.allow for 20+ mcp__memory__* tools so hook-driven calls don't prompt for confirmation
  7. Installs background services for the current OS:
    • macOS — 4 LaunchAgents (reflection, orphan-backfill, check-updates, dashboard) under ~/Library/LaunchAgents/
    • Linux / WSL2 — 7 systemd --user units (*.service, *.timer, *.path) under ~/.config/systemd/user/; gracefully degrades if systemd --user is unavailable (WSL without /etc/wsl.conf)
  8. Applies all migrations to a fresh memory.db
  9. Starts the dashboard at http://127.0.0.1:37737

Restart Claude Code → /mcp → memory should show Connected with 74 tools.

Path A — native (Windows 10/11)

git clone https://github.com/vbcherepanov/total-agent-memory.git $HOME\total-agent-memory
cd $HOME\total-agent-memory
powershell -ExecutionPolicy Bypass -File install.ps1 -Ide claude-code

Same 9 steps as Unix, but:

  • MCP config path is %USERPROFILE%\.claude\settings.json (or .cursor\mcp.json, etc.)
  • Hooks copied to %USERPROFILE%\.claude\hooks\ — .ps1 versions (auto-capture, memory-trigger, user-prompt-submit, post-tool-use, pre-edit, on-bash-error, session-start/end, on-stop, codex-notify)
  • Background services via Task Scheduler:
    • total-agent-memory-reflection — every 5 min (no native FileSystemWatcher equivalent)
    • total-agent-memory-orphan-backfill — daily 00:00 + 6h repetition
    • total-agent-memory-check-updates — weekly Mon 09:00
    • TotalAgentMemoryDashboard — AtLogon

Uninstall

All installers preserve ~/.tam/memory.db (legacy installs: ~/.claude-memory/memory.db) and your config files; only services + hook registrations are removed.

./install.sh --uninstall          # macOS/Linux/WSL2 — removes LaunchAgents OR systemd units
.\install.ps1 -Uninstall          # Windows — unregisters Scheduled Tasks + cleans settings.json

Diagnose

One-shot health check — prints ✓/✗ for each subsystem (OS detect, venv, MCP import, services, dashboard HTTP, Ollama, DB migrations):

bash scripts/diagnose.sh          # macOS / Linux / WSL2
.\scripts\diagnose.ps1            # Windows

Exit code 0 = all green, 1 = something broken.

Path B — Docker (everything containerized, cross-platform)

git clone https://github.com/vbcherepanov/total-agent-memory.git
cd total-agent-memory
bash install-docker.sh --with-compose

Brings up 5 services:

Service Role Exposed
mcp MCP server (HTTP transport) 127.0.0.1:3737/mcp
dashboard Web UI 127.0.0.1:37737
ollama Local LLM runtime 127.0.0.1:11434
reflection File-watch queue drainer internal
scheduler Ofelia cron (backfill + update check) internal

First run pulls qwen2.5-coder:7b (~4.7 GB) + nomic-embed-text (~275 MB) — 5–10 min cold start.

GPU note: Docker Desktop on macOS doesn't forward Metal. Native install is faster on Mac. On Linux with NVIDIA Container Toolkit, uncomment the deploy.resources.reservations.devices block in docker-compose.yml.

Verify (both paths)

memory_save(content="install works", type="fact")
memory_stats()

Open http://127.0.0.1:37737/ — dashboard, knowledge graph, token savings.

Quick start

v11 default is MEMORY_MODE=fast. No LLM, no Ollama, no network in the save/search/recall hot path. To restore v10.5 synchronous-LLM behaviour set export MEMORY_MODE=deep. Mode switching: LAUNCH.md § Tuning.

Once installed, in any Claude Code / Codex CLI / Cursor session:

1. Resume where you left off (auto on session start, but you can also invoke)

session_init(project="my-api")
→ {summary: "yesterday: migrated auth middleware to JWT",
   next_steps: ["update OpenAPI spec", "notify frontend team"],
   pitfalls: ["don't revert migration 0042 — dev DB already migrated"]}

2. Save a decision (agent does this automatically after hooks are registered)

memory_save(
  type="decision",
  content="Chose pgvector over ChromaDB for multi-tenant RLS",
  context="WHY: single Postgres instance, per-tenant row-level security",
  project="my-api",
  tags=["database", "multi-tenant"],
)

3. Recall across sessions / projects

memory_recall(query="vector database choice", project="my-api", limit=5)
→ RRF-fused results from 6 retrieval tiers

4. Predict approach before starting a task

workflow_predict(task_description="migrate auth middleware to JWT-only")
→ {confidence: 0.82, predicted_steps: [...], similar_past: [...]}

5. Check a file's risk before editing (auto via hook, also manual)

file_context(path="/Users/me/my-api/src/auth/middleware.go")
→ {risk_score: 0.71, warnings: ["last 3 edits caused test failures in ..."], hot_spots: [...]}

6. Get full stats

memory_stats()
→ {sessions: 515, knowledge: {active: 1859, ...}, storage_mb: 119.5, ...}

CLI: lookup-memory for sub-agents

New in v9. Bash-friendly memory search for sub-agent workflows where launching the full MCP server would be overkill (e.g. Bash(lookup-memory "fix slow Wave query") from inside a Claude Code agent prompt).

Two equivalent commands ship with the package (registered as [project.scripts] entries — installed automatically by ./install.sh or ./update.sh):

lookup-memory "Caroline researched"          # human-readable bullets
tam-lookup "Caroline researched"             # short canonical alias
ctm-lookup "Caroline researched"             # legacy alias (v11.x and earlier)

lookup-memory --project myproj --limit 5 "auth flow"
lookup-memory --type solution --tag reusable "fix bug"
lookup-memory --json "claude code hooks"     # structured stdout for piping

How it works: opens the same $TAM_MEMORY_DIR/memory.db (legacy: $CLAUDE_MEMORY_DIR/memory.db) the running MCP server uses → BM25 ranking via FTS5 → falls back to LIKE on older DBs. Zero deps beyond the package. No Ollama, no rag_chat.py, no ChromaDB required for the CLI path. Works on macOS, Linux, Windows.

$ lookup-memory --project locomo_0 --limit 2 "adoption"

2. [synthesized_fact|locomo_0] Melanie congratulates Caroline on her adoption.

Why three names? lookup-memory matches the legacy bash script that older docs and sub-agent prompts reference (~/claude-memory-server/ollama/lookup_memory.sh, legacy install path). tam-lookup is the new project-prefixed canonical form (v12+). ctm-lookup is the v11.x prefixed name, kept as a legacy alias. All three call into total_agent_memory.lookup:main (v11.x and earlier: claude_total_memory.lookup:main, still importable via deprecation shim).

Migration note: v7/v8 docs that pointed at ~/claude-memory-server/ollama/lookup_memory.sh should be updated — the bash version still works for users with a manual install, but ./install.sh / ./update.sh clients on v9+ now get lookup-memory (and tam-lookup) on PATH directly via the package's [project.scripts] entry.

Skills (3): memory_skill_get, memory_skill_update, file_context

Total: 74 tools. Each is documented below with input schema and example.

Every tool carries MCP behaviour annotations — 38 are marked readOnlyHint, and memory_delete / memory_forget / memory_update / kg_invalidate_fact plus the two rebuild tools are marked destructiveHint. Clients use these to decide what may run without a confirmation prompt. Tools that answer in JSON also return it as structuredContent, so you do not have to parse the text.

Token-efficient 3-layer workflow

When you only know the topic but not which records matter, use progressive disclosure:

  1. Index — memory_recall(query="auth refactor", mode="index", limit=20) → ~2 KB of {id, title, score, type, project, created_at} per hit. No content, no cognitive expansion.
  2. Timeline — memory_recall(query="auth refactor", mode="timeline", limit=5, neighbors=2) → top-K hits padded with ±neighbours from the same session, sorted chronologically.
  3. Fetch — memory_get(ids=[3622, 3606]) → full content for ONLY the IDs you chose (max 50 per call, detail="summary" truncates to 150 chars).

Typical saving: 80-90 %% fewer tokens vs memory_recall(detail="full", limit=20) when you end up using 2-3 of the 20 hits.

Update

cd ~/total-agent-memory   # legacy clones: ~/claude-memory-server
./update.sh

7 stages:

  1. Pre-flight — disk check + DB snapshot (keeps last 7)
  2. Source pull (git) or SHA-256-verified tarball
  3. Deps — pip install -r requirements.txt -r requirements-dev.txt (only if hash changed)
  4. Full pytest suite — aborts with snapshot if red
  5. Schema migrations — python src/tools/version_status.py
  6. LaunchAgent reload — reflection + backfill + update-check
  7. MCP reconnect notification — in-app /mcp → memory → Reconnect

Manual equivalent:

cd ~/total-agent-memory   # legacy clones: ~/claude-memory-server
git pull
.venv/bin/pip install -r requirements.txt -r requirements-dev.txt
.venv/bin/python src/tools/version_status.py
.venv/bin/python -m pytest tests/
# in Claude Code: /mcp → memory → Reconnect

Upgrading from v8.x to v9.0

v9 is backward compatible. Existing v8 calls and DB schema work unchanged — v9 is an infra release that adds pluggable backends, a public CLI for sub-agents, and LoCoMo benchmark wiring. Nothing is forcibly enabled.

One-command upgrade

cd ~/total-agent-memory && ./update.sh   # legacy clones: ~/claude-memory-server
# pulls v9 src, installs new entry-points (tam, tam-lookup, lookup-memory; legacy: ctm-lookup),
# keeps existing memory.db untouched.

After upgrade, verify the new CLI is on PATH:

lookup-memory --limit 1 "any-query-from-your-history"

What's new (no action required)

  • lookup-memory / tam-lookup / ctm-lookup (legacy) CLI now installed alongside total-agent-memory MCP server (registered as [project.scripts] so ./install.sh and ./update.sh put them on PATH automatically). Sub-agent prompts that reference the legacy ~/claude-memory-server/ollama/lookup_memory.sh script keep working; new prompts should prefer the package-installed name.
  • Embedding backends stay on fastembed by default. Switch via V9_EMBED_BACKEND=openai-3-large (set MEMORY_EMBED_API_KEY) — costs ~$0.10/5k rows for re-embed, expected R@5 lift on conversational data.
  • Reranker backend stays on ce-marco by default. V9_RERANKER_BACKEND=bge-v2-m3 (or off) switches at runtime.
  • Subject-aware retrieval is opt-in via --subject-aware in benchmarks/locomo_bench_llm.py. Future: surface as MCP tool flag.
  • No migrations. Schema unchanged from v8.

What requires manual action

  • Re-embed (only if switching embedding model, otherwise skip): 
    python -m scripts.reembed --backend openai-3-large --confirm
  • Old bash sub-agent prompts that hardcode ~/claude-memory-server/ollama/lookup_memory.sh "query" will keep working. To ride the new package install, replace with lookup-memory "query".

Breaking changes

None. All v8 MCP tools, env vars, hooks, and DB tables behave identically.

Upgrading from v7.x to v8.0

v8.0 is backward compatible — your existing v7 installation keeps working unchanged. All new features are opt-in via MCP tool calls or env vars.

One-command upgrade

cd ~/total-agent-memory && ./update.sh   # legacy clones: ~/claude-memory-server
# Applies migrations 011-013 idempotently, restarts LaunchAgents, updates dependencies

Then restart Claude Code: /mcp restart memory.

What changes automatically

  • Migrations 011–013 apply on MCP startup (privacy_counters, task_phases, intents). Zero-downtime, idempotent.
  • Existing memory_save calls keep working — they now additionally strip <private>...</private> sections if present.
  • Existing memory_recall calls keep working — default mode is still "search". New mode="index" is opt-in.
  • Existing session_end calls keep working — auto_compress=False by default. Pass auto_compress=True to opt in.
  • Existing self_rules_context calls keep working — default returns all rules (no phase filter).

What requires manual setup

1. Cloud providers (only if you want to replace/augment Ollama):

export MEMORY_LLM_PROVIDER=openai       # or "anthropic"
export MEMORY_LLM_API_KEY=sk-...
export MEMORY_LLM_MODEL=gpt-4o-mini     # or "claude-haiku-4-5"

See Cloud providers for OpenRouter / per-phase routing / Cohere examples.

2. Install additional hooks (for UserPromptSubmit capture + citation):

./install.sh --ide claude-code   # re-run installer; it now registers user-prompt-submit.sh hook

The hook is additive — existing hooks keep working.

3. activeContext.md Obsidian integration (if you want markdown projection):

export MEMORY_ACTIVECONTEXT_VAULT=~/Documents/project/Projects   # default
# Disable: export MEMORY_ACTIVECONTEXT_DISABLE=1

Each session_end writes <vault>/<project>/activeContext.md.

Breaking changes

None. All v7 MCP tool signatures are preserved. New parameters are optional with safe defaults.

Embedding dimension note

If you switch to a cloud embedding provider (MEMORY_EMBED_PROVIDER=openai/cohere), the server will refuse to start if existing DB embeddings have a different dimension than the new provider returns. This is deliberate — it prevents silent data corruption.

Either:

  • Keep MEMORY_EMBED_PROVIDER=fastembed (default 384d) and only change the LLM provider, OR
  • Re-embed the DB: python src/tools/reembed.py --provider openai --model text-embedding-3-small

New MCP tools in v8.0

Quick reference — see full docs in MCP tools reference:

Tool Purpose
classify_task(description) Returns {level 1-4, suggested_phases, estimated_tokens}
task_create(task_id, description) Starts state machine in "van" phase
phase_transition(task_id, new_phase, artifacts?) Moves task through van/plan/creative/build/reflect/archive
task_phases_list(task_id) Chronological phase history
save_decision(title, options, criteria_matrix, selected, rationale, ...) Structured decision with per-criterion indexing
memory_get(ids, detail) Batched full-content fetch for IDs from memory_recall(mode="index")
save_intent / list_intents / search_intents UserPromptSubmit-captured prompts
rule_set_phase(rule_id, phase) Tag a rule for phase-scoped loading

Extended tools:

  • memory_recall(mode="index"|"timeline", decisions_only=False, ...) — 3-layer token-efficient workflow
  • session_end(auto_compress=True, transcript=None, ...) — LLM-generated summary
  • self_rules_context(phase="build"|"plan"|...) — phase filter
  • save_knowledge(...) — now strips <private>...</private> sections automatically

Rollback plan

v8.0 doesn't remove any v7 functionality. If you hit an issue, you can:

  1. Set env var to revert behaviour:

    export MEMORY_LLM_PROVIDER=ollama           # revert to local LLM
export MEMORY_EMBED_PROVIDER=fastembed      # revert to local embeddings
export MEMORY_ACTIVECONTEXT_DISABLE=1       # disable markdown projection
export MEMORY_POST_TOOL_CAPTURE=0           # disable opt-in capture (default anyway)

  2. Migrations 011/012/013 are additive (no DROP / ALTER on existing tables), so DB downgrade is not destructive — old code continues reading older tables.

  3. Worst case: git checkout v7.0.0 && ./update.sh --skip-migrations.

Ollama setup (optional but recommended)

Without Ollama: works fully — raw content is saved, retrieval via BM25 + FastEmbed dense embeddings.

With Ollama: you also get LLM-generated summaries, keywords, question-forms, compressed representations, and deep enrichment (entities, intent, topics).

brew install ollama     # or: curl -fsSL https://ollama.com/install.sh | sh
ollama serve &
ollama pull qwen2.5-coder:7b        # default — best quality/speed on M-series
ollama pull nomic-embed-text        # optional, alternative embedder

Cloud providers (optional)

Use OpenAI, Anthropic, or any OpenAI-compat endpoint (OpenRouter, Together, Groq, DeepSeek, LM Studio, llama.cpp) instead of local Ollama.

OpenAI:

export MEMORY_LLM_PROVIDER=openai
export MEMORY_LLM_API_KEY=sk-...
export MEMORY_LLM_MODEL=gpt-4o-mini

Anthropic:

export MEMORY_LLM_PROVIDER=anthropic
export MEMORY_LLM_API_KEY=sk-ant-...
export MEMORY_LLM_MODEL=claude-haiku-4-5

OpenRouter (100+ models via one endpoint):

export MEMORY_LLM_PROVIDER=openai
export MEMORY_LLM_API_BASE=https://openrouter.ai/api/v1
export MEMORY_LLM_API_KEY=sk-or-...
export MEMORY_LLM_MODEL=anthropic/claude-haiku-4.5

Per-phase routing (cheap model for bulk, quality for compression):

export MEMORY_TRIPLE_PROVIDER=openai
export MEMORY_TRIPLE_MODEL=gpt-4o-mini
export MEMORY_ENRICH_PROVIDER=anthropic
export MEMORY_ENRICH_MODEL=claude-haiku-4-5

Embeddings (dimension must match existing DB or re-embed required):

export MEMORY_EMBED_PROVIDER=openai
export MEMORY_EMBED_MODEL=text-embedding-3-small  # 1536d
# or Cohere:
export MEMORY_EMBED_PROVIDER=cohere
export MEMORY_EMBED_API_KEY=...

Model choice

Model Size Use case
qwen2.5-coder:7b 4.7 GB default — best quality/speed ratio
qwen2.5-coder:32b 19 GB highest quality, needs 32 GB+ RAM
llama3.1:8b 4.9 GB general-purpose alternative
phi3:mini 2.3 GB low-RAM machines

Configuration

Environment variables (all optional):

v11.0 — Memory mode + multi-embedding-space

Variable Default Purpose
MEMORY_MODE fast ultrafast|fast|balanced|deep. Selects hot-path profile. See Performance tuning.
MEMORY_USE_LLM_IN_HOT_PATH false Master switch for sync LLM stages in save_knowledge / Recall.search. MEMORY_MODE=deep flips this to true.
MEMORY_ALLOW_OLLAMA_IN_HOT_PATH false Re-enables the silent FastEmbed → Ollama fallback ladder when FastEmbed is unavailable.
MEMORY_NEGATIVE_RETRIEVAL true memory_answer runs the contradiction-seeking second search (one inversion call + one batched scoring call over at most 5×5 pairs). false skips it.
MEMORY_CONTRADICTION_POLICY resolve What memory_answer does when that search finds a hard contradiction. resolve hands both sides, with their recording dates, to the reader, which answers with the latest value and names the one it replaced. abstain answers Not enough information without reading (the 14.1.0 behaviour).
MEMORY_CONTRADICTION_SCORER llm Who scores the (supporting, opposing) pairs of that search. llm uses the reasoning provider. jev sends every pair as one noul question in a single request to TypeSafe's System One API (model Jev); needs TYPESAFE_API_KEY. If the scorer fails, the pass reports no contradiction and the answer proceeds.
TYPESAFE_API_KEY unset Key for MEMORY_CONTRADICTION_SCORER=jev. Empty keys and keys with control characters are rejected before any request, without echoing the key.
TYPESAFE_BASE_URL / TYPESAFE_DEFAULT_MODEL https://api.typesafe.ai / jev-latest Endpoint and model for the Jev scorer (self-hosted servers speaking /v1/systemone work too).
MEMORY_RERANK_ENABLED false Honour caller's rerank=true. When false, CrossEncoder rerank is hard-disabled even if a tool call requests it.
MEMORY_ENRICHMENT_ENABLED false Run the async enrichment worker. Default-ON in balanced / deep.
MEMORY_TEXT_EMBED_MODEL sentence-transformers/paraphrase-multilingual-MiniLM-L12-v2 Model for embedding_space=text (every record that is not code, log or config). For an English-only store, BAAI/bge-base-en-v1.5 retrieves better (LoCoMo evidence in context 81.8% → 86.2%) but handles other languages poorly. Changing it on an existing store needs python src/reembed.py --fastembed. FASTEMBED_MODEL and MEMORY_EMBED_MODEL, the older names, still win when set.
MEMORY_CROSS_RERANK auto Local cross-encoder over the 50 fused candidates of memory_recall. auto re-ranks once the model has loaded in the background, on waits for it, off keeps the fused order.
MEMORY_CROSS_RERANK_MODEL Xenova/ms-marco-MiniLM-L-6-v2 English-only models are skipped for queries written mostly outside the Latin script; jinaai/jina-reranker-v2-base-multilingual covers other languages.
MEMORY_CROSS_RERANK_CONTEXT 400 Characters of the previous and next turn of the same session the cross-encoder also reads with each candidate, so an answer like "It was about acceptance" is found for "What was the poetry reading about?". 0 scores each record alone.
MEMORY_CONTEXT_RESOLVE_DATES on In memory_recall(mode="context"), follow relative date phrases with the date they denote, counted from the record's leading timestamp or its created_at: "last Thursday [Thu 14 December 2023]", "last week [the week before Sun 17 December 2023]". English and Russian phrases. off returns the records as stored.
MEMORY_CODE_EMBED_MODEL empty → falls back to TEXT model Model for embedding_space=code. The row still records space=code so a future swap is config-only.
MEMORY_LOG_EMBED_MODEL empty → TEXT Model for embedding_space=log.
MEMORY_CONFIG_EMBED_MODEL empty → TEXT Model for embedding_space=config.
MEMORY_DEFAULT_EMBEDDING_SPACE text Space for unclassified content.

v10 + earlier

Variable Default Purpose
MEMORY_DB ~/.tam/memory.db (legacy installs: ~/.claude-memory/memory.db) SQLite location
MEMORY_LLM_ENABLED auto auto|true|false|force — LLM enrichment toggle
MEMORY_LLM_MODEL qwen2.5-coder:7b Ollama model for enrichment
MEMORY_LLM_PROBE_TTL_SEC 60 Cache TTL for Ollama availability probe
MEMORY_LLM_TIMEOUT_SEC 60 Global fallback timeout for Ollama requests (s)
MEMORY_TRIPLE_TIMEOUT_SEC 30 Timeout for deep triple extraction (s)
MEMORY_ENRICH_TIMEOUT_SEC 45 Timeout for deep enrichment (s)
MEMORY_REPR_TIMEOUT_SEC 60 Timeout for representation generation (s)
MEMORY_TRIPLE_MAX_PREDICT 2048 num_predict cap for triple extraction
OLLAMA_URL http://localhost:11434 Ollama endpoint
MEMORY_EMBED_MODE fastembed fastembed|sentence-transformers|ollama
DASHBOARD_PORT 37737 HTTP dashboard port
MEMORY_MCP_PORT 3737 HTTP MCP transport port (Docker path)
MEMORY_ASYNC_ENRICHMENT false v10.1 — move quality gate / contradiction / entity dedup / episodic / wiki to a background worker. See Performance tuning
MEMORY_ENRICH_TICK_SEC 0.1 Worker tick interval (clamp 0.01..5)
MEMORY_ENRICH_BATCH 5 Rows claimed per tick (clamp 1..50)
MEMORY_ENRICH_MAX_ATTEMPTS 3 Retries before flipping a row to failed
MEMORY_ENRICH_STALE_AFTER_SEC 60 Seconds before a processing row is reclaimed (worker crash recovery)

CPU-only / WSL hosts: if Ollama keeps timing out, lower MEMORY_TRIPLE_MAX_PREDICT before raising timeouts. install-codex.sh writes conservative defaults automatically. For 30-40s save latency on WSL2 → set MEMORY_ASYNC_ENRICHMENT=true — see below.

Full config: see total_agent_memory/config.py.

Performance tuning

v11.0 fast-mode hot path (default)

When MEMORY_MODE=fast (default):

metric p50 p95 p99
save_fast 6.2 8.9 11.4
save_fast cached 0.3 0.4 1.4
search_fast 3.4 4.7 6.0
cached_search 3.1 3.4 3.6

llm_calls=0, network_calls=0. Reproduce: ./bin/memory-bench. Regression gate: ./bin/memory-perf-gate. Architecture rationale and per-stage audit: docs/v11/audit.md. Raw bench artifact: docs/v11/benchmark.md.

If your numbers do not match the table, run ./bin/memory-bench --warmup first — cold FastEmbed import dominates the first call.

Legacy: v10.5 deep-mode memory_save latency

The synchronous v10 hot path runs five LLM-bound stages inline so a drop verdict can block the INSERT and a contradiction supersede commits in the same transaction. On macOS with a warm Ollama that's ~340 ms median; on a WSL2 box without GPU/CoreML each LLM round-trip can stretch the same call into 30–40 seconds.

v10.1 ships an opt-in inbox/outbox worker that moves the heavy stages out of band:

sync   : privacy → canonical_tags → INSERT → embed → enqueue → return
worker : quality_gate → entity_dedup_audit → contradiction → episodic → wiki

Enable it in your env:

export MEMORY_ASYNC_ENRICHMENT=true
# Optional knobs (defaults shown):
export MEMORY_ENRICH_TICK_SEC=0.1
export MEMORY_ENRICH_BATCH=5
export MEMORY_ENRICH_MAX_ATTEMPTS=3
export MEMORY_ENRICH_STALE_AFTER_SEC=60

Restart the MCP server. A background daemon thread now consumes enrichment_queue; you can watch it on the dashboard panel ⚡ v10.1 enrichment worker.

Bench v10.5 (10-record corpus × 2 rounds, with LLM stages on)

memory_save latency:

min p50 p95 p99 max mean
sync (default) 17.5 ms 25.3 ms 2150.5 ms 2179.0 ms 2186.1 ms 348.0 ms
async (MEMORY_ASYNC_ENRICHMENT=true) 18.1 ms 22.3 ms 26.7 ms 27.4 ms 27.5 ms 22.7 ms

memory_recall latency: p50 ≈ 3-5 ms in both modes (steady state), with cold-cache p95 outliers on the first warmup hit.

p95 collapses 80× with async (2150 ms → 27 ms). On WSL2 with a slow Ollama, the same shape holds — sync p95 of 30-40 s becomes async p95 of ~300-1000 ms (LLM moves out of the hot path entirely).

Reproduce: ./.venv/bin/python benchmarks/v10_5_latency.py --rounds 2 --with-llm. Full report: benchmarks/v10_5_results.md.

Trade-off — soft drop semantic

When async is on, a quality_gate drop no longer prevents the INSERT (we already committed in the sync path). Instead the row is marked status='quality_dropped' after the worker scores it. memory_recall ignores that status (idx_knowledge_status_quality is added in migration 020). Audit history stays in quality_gate_log so nothing is lost.

If you need strict pre-INSERT gating (e.g. compliance), keep the default sync path.

Crash recovery

Rows stuck in processing longer than MEMORY_ENRICH_STALE_AFTER_SEC (default 60 s) are flipped back to pending automatically — covers worker process kills mid-stage. The pre-existing write_intents outbox still covers a crash before INSERT.

Roadmap

Shipped in v13.0.0 (2026-08-27)

  • ✅ MCP SDK 2.x compatibility — the blocker: every install created after mcp 2.0 shipped was dead on arrival. Tools register through either SDK era; dependency bounded >=1.9,<3.
  • ✅ Protocol revision 2026-07-28 — stateless era served end-to-end (tools/list / server/discover / tools/call with no handshake), legacy handshake era from the same process, structuredContent on JSON-answering tools, behaviour annotations on all 74.
  • ✅ Claude Code plugin — /plugin install total-agent-memory@vbcherepanov wires the MCP server, the skill and seven hooks in one step.
  • ✅ Reproducible benchmarks — record_usage=False stops runs from measuring their own history; category labels in the LoCoMo runner corrected.
  • ✅ BEAM (ICLR 2026) added to the suite at 100K / 500K / 1M.
  • ✅ tree-sitter-language-pack is now an actual dependency — AST ingest had been silently degrading to whole-file chunks for every user.
  • ✅ Enrichment worker owns its sqlite connection — long ingests no longer die on cannot start a transaction within a transaction.

Shipped in v11.0 (2026-04-27) — production memory engine

  • ✅ Default MEMORY_MODE=fast — zero LLM, zero Ollama, zero network in save/search/recall hot path. Set MEMORY_MODE=deep to restore v10.5 behaviour.
  • ✅ Memory Core / AI Layer split — src/memory_core/* is deterministic; src/ai_layer/* owns every LLM-bound code path. Enforced by tests/test_no_llm_hot_path.py.
  • ✅ 4 modes: ultrafast / fast / balanced / deep. Single env flag.
  • ✅ Multi-embedding-space contract — every vector row records provider / model / dimension / space / content_type / language. Spaces: text / code / log / config. Single Chroma backend; per-space model swap is config-only.
  • ✅ Embed fallback ladder gated — silent Ollama fallback in Store.embed requires MEMORY_ALLOW_OLLAMA_IN_HOT_PATH=true.
  • ✅ New MCP tools: memory_save_fast, memory_search_fast, memory_explain_search, memory_warmup, memory_perf_report, memory_rebuild_fts, memory_rebuild_embeddings, memory_eval_locomo, memory_eval_recall, memory_eval_temporal, memory_eval_entity_consistency, memory_eval_contradictions, memory_eval_long_context.
  • ✅ Migrations 021 (embedding_spaces) + 022 (embedding_cache_v11) — idempotent on next start.
  • ✅ Benchmark suite: bin/memory-bench (artifact docs/v11/benchmark.md) + bin/memory-perf-gate for CI.

Shipped in v10.5 (2026-04-27)

  • ✅ Universal memory-protocol skill — single canonical SKILL.md + 4 references (tool cheatsheet for all MCP tools, workflow recipes for 15 common situations, hooks reference, per-IDE setup) + 4 templates (Claude Code settings.json, Codex config.toml, Cursor .mdc, Cline .md). Same content for every IDE; only the wiring differs.
  • ✅ install.sh --ide extended to 9 IDEs: claude-code, codex, cursor, cline, continue, aider, windsurf, gemini-cli, opencode. New helpers: register_mcp_cline / continue / aider / windsurf + _json_merge_mcp_nested for the dotted-key case (cline.mcpServers).
  • ✅ Cross-platform hardening — all bash scripts pass bash -n under macOS bash 3.2 (default). Replaced ${var,,} lowercase bashism in update.sh with tr '[:upper:]' '[:lower:]'. Verified with shellcheck.
  • ✅ Sub-agent memory protocol — universal header for any sub-agent (php-pro, golang-pro, vue-expert, etc.) with mandatory memory_recall before / memory_save after. Full template in skills/memory-protocol/references/subagent-protocol.md.
  • ✅ v10.5 latency benchmark — benchmarks/v10_5_latency.py with apples-to-apples sync vs async comparison. Demonstrates 80× p95 reduction (2150 ms → 27 ms) when async is enabled with LLM stages on.

Shipped in v10.1 (2026-04-27)

  • ✅ Async enrichment worker — opt-in MEMORY_ASYNC_ENRICHMENT=true moves quality gate / entity dedup / contradiction detector / episodic linking / wiki refresh to a background thread. Drops max save latency 5.4× on macOS, 60–100× on WSL2. See Performance tuning.
  • ✅ enrichment_queue table with stale-processing recovery (rows stuck >60 s in processing flip back to pending).
  • ✅ Dashboard panel for worker health: depth, throughput/min, p50/p95 ms per task, oldest pending age, recent failures.
  • ✅ _binary_search ValueError fix — np.argpartition requires kth STRICTLY < N; tiny test projects (pool ≤ 50) used to silently break contradiction_log.
  • ✅ coref_resolver RU→EN translation fix — prompt explicitly pins output language (Do NOT translate).

Shipped in v10.0 (2026-04-27)

  • ✅ 10 Beever-Atlas-inspired features in one push: quality gate (Beever 6-Month Test), canonical tag vocabulary, importance boost in recall, opt-in coref resolution, contradiction auto-detection with supersede, write-intent outbox + reconciler, embedding-based entity dedup, episodic save events in the graph, smart query router (relational vs lexical), per-project Markdown wiki digest.
  • ✅ 5 SQLite migrations (015–019) applied automatically on restart.
  • ✅ 11 new env knobs, all with safe fail-open defaults.
  • ✅ Tests: 971 → 1124 (+153).

Shipped in v9.0 (2026-04-25)

  • ✅ lookup-memory / tam-lookup / ctm-lookup (legacy) CLI — bash entry-point for sub-agents, registered as [project.scripts] and installed by ./install.sh / ./update.sh (replaces manual ~/claude-memory-server/ollama/lookup_memory.sh)
  • ✅ Pluggable embedding backends: openai-3-small, openai-3-large (3072d), bge-m3, e5-large, locomo-tuned-minilm (fine-tuned on user data)
  • ✅ Pluggable reranker backends: ce-marco, bge-v2-m3, bge-large, off (env V9_RERANKER_BACKEND, hot-swap)
  • ✅ Subject-aware retrieval — LLM extracts (subject, action) from question → SQL graph lookup → DIRECT FACTS prepended to context (LoCoMo cat 1/2 lift)
  • ✅ Judge-weighted ensemble — category-aware scoring rubric + abstain logic for LoCoMo-style adversarial gold
  • ✅ Fine-tune embedding pipeline (scripts/finetune_embedding.py) — mine triplets from your data, train on top of MiniLM via sentence-transformers
  • ✅ Few-shot pair mining (scripts/mine_locomo_fewshot.py) — augment per-category prompts with held-in (Q,A) pairs
  • ✅ Schema-specific graph extractor (closed canonical predicate vocabulary, optional)
  • ✅ SSL fix for macOS Python.org installs — urllib requests now use certifi by default
  • ✅ HTTP retry with exponential backoff for embedding providers (5xx/timeout)
  • ✅ LoCoMo benchmark integration (benchmarks/locomo_bench_llm.py with 14 ablation flags)

Shipped in v8.0 (2026-04-19)

  • ✅ Task workflow phases (L1-L4 classifier + 6-phase state machine)
  • ✅ Structured save_decision with criteria matrix + multi-representation criterion indexing
  • ✅ Cloud LLM/embed providers (OpenAI, Anthropic, Cohere, any OpenAI-compat)
  • ✅ session_end(auto_compress=True) via LLM provider
  • ✅ Progressive disclosure: memory_recall(mode="index") + memory_get(ids)
  • ✅ activeContext.md Obsidian live-doc projection
  • ✅ Phase-scoped rules via tag filter
  • ✅ <private>...</private> inline redaction
  • ✅ HTTP citation endpoints /api/knowledge/{id} + /api/session/{id}
  • ✅ UserPromptSubmit + PostToolUse (opt-in) capture hooks
  • ✅ Unified install.sh --ide {claude-code|cursor|gemini-cli|opencode|codex}

Next — what the v13 numbers say to fix

The benchmarks point at specific gaps rather than a general "make retrieval better", so the roadmap names them:

  • instruction_following R@5 = 0.075, event_ordering = 0.150 (BEAM). These probes ask whether a stated instruction was followed or in what order things happened. Semantic similarity to the question does not find the message where the instruction was given — retrieval is the wrong primitive. Needs a directive index (statements of the form "always/never/from now on") and ordering-aware traversal over the episodic graph.
  • multi-hop R@5 = 0.413 (LoCoMo). Weakest category, and the one where the leaders win. Query decomposition without putting an LLM back in the hot path is the open design question.
  • single_session_preference R@5 = 0.80 (LongMemEval), preference_following = 0.282 (BEAM). The same weakness from two directions: preferences are stated once, in passing, and never restated.
  • BEAM-10M. The 1M scale runs today; 10M is the interesting claim.
  • Search is linear in store size. BEAM 1M measured p50 411 ms against 58 ms at 500K — Store._binary_search loads every active record's binary vector into numpy per query. An ANN index over those vectors is the obvious answer. This is the largest open performance item.
  • Profile the write path — done in v13.0.1: auto_link constructed a ConceptExtractor per save and threw away its node cache, re-reading the whole graph_nodes table on every write.

Planned

  • GitHub Actions: install smoke tests + a nightly retrieval gate, so a regression in R@5 fails CI the way bin/memory-perf-gate already fails on latency.
  • has_llm() per-phase provider caching.

Under research

  • "Endless mode" — continuous session without hard boundaries (virtual sessions by idle >N hours)
  • MLX local LLM integration
  • Speculative decoding for local path (+1.5-1.8× LLM speed)

🎧 $100 — a weekend A major feature: e.g. the preference-tracking module that closes the 80% gap on LongMemEval
💎 $500+ — a sprint A release cycle: new subsystem + migrations + docs + benchmark artifact

Non-monetary ways to help (equally appreciated)

  • ⭐ Star the repo — GitHub discovery runs on this
  • 🐦 Share benchmarks on X / HN / Reddit — reach matters more than donations
  • 🐛 Open issues with repro cases — bug reports are pure gold
  • 📝 Write a blog post about how you use it
  • 🔧 Submit a PR — fixes, new tools, new integrations
  • 🌍 Translate the README — first docs in RU / DE / JA / ZH very welcome
  • 💬 Tell your team — peer recommendations convert 10× better than marketing

Commercial / consulting

  • Building something that would benefit from a custom integration, on-prem deployment, or team-shared memory? Email vbcherepanov@gmail.com — open to contract work and partnerships.
  • AI / dev-tools company whose roadmap overlaps? Same email — happy to talk.

Philosophy

MIT forever. No commercial-license switch, no VC money, no dark patterns. The memory layer belongs to the developers using it, not to a SaaS vendor.

Local-first is the product. If you want a cloud memory service, mem0 and Supermemory are great. If you want your data on your disk, untouched by anyone else — this.

Honest benchmarks. Every number on this page is reproducible from the artifacts in evals/ and the scripts in benchmarks/. If you can't reproduce a claim, open an issue — it's a bug.

Contributing

  • Open an issue before a large PR — saves everyone time.
  • pytest tests/ must stay green. Add tests for new tools.
  • Update evals/scenarios/*.json if you change retrieval behavior.
  • Docs-only / typo PRs welcome without discussion.
