consolidation-memory 0.13.5

Local-first persistent memory for AI agents - store, recall, and consolidate knowledge across sessions using FAISS, SQLite, and any LLM

consolidation-memory

Local-first persistent memory for coding agents.

consolidation-memory stores episodic events, consolidates them into structured knowledge, and exposes a trust-aware retrieval stack (temporal recall, contradiction tracking, claim provenance, and drift challenge workflows).

What It Is

• Episode storage with semantic dedup and FAISS indexing.
• Hybrid recall across episodes, knowledge topics, structured records, and claims.
• Claim graph with provenance (claim_sources) and lifecycle events (claim_events).
• Temporal queries (as_of) for both knowledge and claims.
• Drift detection that maps changed files to anchored claims and marks impacted claims challenged.
• Multi-scope persistence (namespace/project/app/agent/session columns) with compatibility defaults.
• Four access surfaces:
  • MCP server (consolidation-memory serve)
  • Python API (MemoryClient)
  • REST API (consolidation-memory serve --rest)
  • OpenAI-style tool schemas (consolidation_memory.schemas.openai_tools)

Install

pip install consolidation-memory[fastembed]

Common extras:

• consolidation-memory[rest] for FastAPI endpoints
• consolidation-memory[dashboard] for the Textual dashboard
• consolidation-memory[all,dev] for full local development

Quick Start

MCP Setup

{
  "mcpServers": {
    "consolidation_memory": {
      "command": "consolidation-memory",
      "args": ["--project", "default", "serve"]
    }
  }
}

MCP tools exposed by server.py:

• memory_store
• memory_recall
• memory_store_batch
• memory_search
• memory_claim_browse
• memory_claim_search
• memory_detect_drift
• memory_status
• memory_forget
• memory_export
• memory_correct
• memory_compact
• memory_consolidate
• memory_consolidation_log
• memory_decay_report
• memory_protect
• memory_timeline
• memory_contradictions
• memory_browse
• memory_read_topic

Python Example

from consolidation_memory import MemoryClient

with MemoryClient(auto_consolidate=False) as mem:
    mem.store(
        "User prefers short PR summaries with concrete file paths.",
        content_type="preference",
        tags=["workflow", "reviews"],
    )

    result = mem.recall(
        "how should I format PR summaries?",
        n_results=5,
        include_knowledge=True,
    )

    print(len(result.episodes), len(result.knowledge), len(result.records), len(result.claims))

REST API

Run:

pip install consolidation-memory[rest]
consolidation-memory serve --rest --host 127.0.0.1 --port 8080

For non-loopback binds (for example --host 0.0.0.0), set auth first:

export CONSOLIDATION_MEMORY_REST_AUTH_TOKEN="change-me"
consolidation-memory serve --rest --host 0.0.0.0 --port 8080

When auth is enabled, send Authorization: Bearer <token> on all endpoints except /health.

Endpoints:

• GET /health
• POST /memory/store
• POST /memory/store/batch
• POST /memory/recall
• POST /memory/search
• POST /memory/claims/browse
• POST /memory/claims/search
• POST /memory/detect-drift
• GET /memory/status
• DELETE /memory/episodes/{episode_id}
• POST /memory/consolidate
• POST /memory/correct
• POST /memory/export
• POST /memory/compact
• GET /memory/browse
• GET /memory/topics/{filename}
• POST /memory/timeline
• POST /memory/contradictions
• POST /memory/protect
• POST /memory/consolidation-log
• GET /memory/decay-report

OpenAI-Compatible Tools

Use:

• consolidation_memory.schemas.openai_tools
• consolidation_memory.schemas.dispatch_tool_call

This keeps tool definitions and dispatch behavior aligned with the same semantics used by MCP and REST.

Scope Model (Compatibility + Shared Use)

By default, existing single-project usage still works.

When a scope envelope is provided, records are persisted with explicit scope dimensions:

• namespace_*
• project_*
• app_client_*
• agent_*
• session_*

This allows selective sharing without mixing unrelated contexts.

Storage Layout

Data is under platformdirs.user_data_dir("consolidation_memory")/projects/<project>/.

memory.db
faiss_index.bin
faiss_id_map.json
faiss_tombstones.json
.faiss_reload
knowledge/
knowledge/versions/
consolidation_logs/
backups/

Configuration

Config file discovery:

1. CONSOLIDATION_MEMORY_CONFIG
2. Platform default config path
3. Built-in defaults

Every scalar field can be overridden with CONSOLIDATION_MEMORY_<FIELD_NAME>.

Examples:

CONSOLIDATION_MEMORY_PROJECT=work
CONSOLIDATION_MEMORY_EMBEDDING_BACKEND=fastembed
CONSOLIDATION_MEMORY_LLM_BACKEND=ollama
CONSOLIDATION_MEMORY_CONSOLIDATION_INTERVAL_HOURS=6
