consolidation-memory 0.12.1

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 AI agents. SQLite + FAISS, runs on a laptop, no cloud.

Agents store episodes (conversations, facts, solutions). A background thread periodically clusters related episodes and uses a local LLM to synthesize them into structured knowledge records. Old episodes get pruned. Knowledge compounds over time instead of degrading.

Install

pip install consolidation-memory[fastembed]
consolidation-memory init
consolidation-memory setup-claude  # Add memory instructions to CLAUDE.md

FastEmbed runs locally. No API keys needed. The setup-claude command adds instructions to your ~/.claude/CLAUDE.md so Claude Code proactively uses memory tools.

MCP Server

{
  "mcpServers": {
    "consolidation_memory": {
      "command": "consolidation-memory"
    }
  }
}

Tools: memory_store, memory_store_batch, memory_recall, memory_search, memory_status, memory_forget, memory_export, memory_correct, memory_compact, memory_consolidate, memory_browse, memory_read_topic, memory_timeline, memory_decay_report, memory_protect

Python API

from consolidation_memory import MemoryClient

with MemoryClient() as mem:
    mem.store("User prefers dark mode", content_type="preference", tags=["ui"])

    result = mem.recall("user interface preferences")
    for ep in result.episodes:
        print(ep["content"], ep["similarity"])

OpenAI Function Calling

Works with any OpenAI-compatible API (LM Studio, Ollama, OpenAI, Azure):

from consolidation_memory import MemoryClient
from consolidation_memory.schemas import openai_tools, dispatch_tool_call

mem = MemoryClient()
# Pass openai_tools to your chat completion, dispatch results with dispatch_tool_call()

REST API

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

POST /memory/store | POST /memory/store/batch | POST /memory/recall | POST /memory/search | GET /memory/status | DELETE /memory/episodes/{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 | GET /memory/decay-report | GET /health

How Consolidation Works

store episodes → SQLite + FAISS
                      ↓
        background thread (every 6h)
                      ↓
     hierarchical clustering by similarity
                      ↓
        LLM synthesizes knowledge records
        (facts, solutions, preferences, procedures)
                      ↓
     records feed back into recall, old episodes pruned

Episodes are grouped by semantic similarity using agglomerative clustering. Each cluster is matched against existing knowledge topics. The LLM either creates a new topic or merges into an existing one. Output is validated, versioned, and written as structured records with their own embeddings for independent search.

Three consecutive LLM failures trip a circuit breaker. Pruned episodes still count toward consolidation history.

Configuration

consolidation-memory init

Manual config

Platform	Path
Linux/macOS	~/.config/consolidation_memory/config.toml
Windows	%APPDATA%\consolidation_memory\config.toml
Override	CONSOLIDATION_MEMORY_CONFIG env var

[embedding]

[llm]
backend = "lmstudio"
api_base = "http://localhost:1234/v1"

Environment variable overrides

Every setting can be overridden with CONSOLIDATION_MEMORY_<FIELD_NAME>:

CONSOLIDATION_MEMORY_EMBEDDING_BACKEND=lmstudio
CONSOLIDATION_MEMORY_EMBEDDING_DIMENSION=768
CONSOLIDATION_MEMORY_LLM_BACKEND=openai
CONSOLIDATION_MEMORY_LLM_API_KEY=sk-...

CONSOLIDATION_MEMORY_CONSOLIDATION_AUTO_RUN=false

Priority: defaults < TOML < env vars < reset_config() (tests).

Multi-Project

Isolate memories per project:

consolidation-memory --project work status
CONSOLIDATION_MEMORY_PROJECT=work consolidation-memory serve

MCP config for multiple projects:

{
  "mcpServers": {
    "memory-work": {
      "command": "consolidation-memory",
      "env": { "CONSOLIDATION_MEMORY_PROJECT": "work" }
    },
    "memory-personal": {
      "command": "consolidation-memory",
      "env": { "CONSOLIDATION_MEMORY_PROJECT": "personal" }
    }
  }
}

Each project gets its own database, vector index, and knowledge files.

Cross-Client Memory

One consolidation-memory instance serves every MCP client on your machine. Claude Code, Cursor, Windsurf, VS Code + Continue — all share the same SQLite database and FAISS index. A fact stored from Cursor is recalled in Claude Code. No cloud sync needed.

This is the local-first alternative to cloud-based memory passports. Your data never leaves your machine.

Example configs for each client

Claude Code (claude_desktop_config.json):

{
  "mcpServers": {
    "consolidation_memory": {
      "command": "consolidation-memory"
    }
  }
}

Cursor (.cursor/mcp.json):

{
  "mcpServers": {
    "consolidation_memory": {
      "command": "consolidation-memory"
    }
  }
}

VS Code + Continue (.continue/config.json):

{
  "mcpServers": [
    {
      "name": "consolidation_memory",
      "command": "consolidation-memory"
    }
  ]
}

Generic MCP client (any client supporting stdio transport):

{
  "command": "consolidation-memory",
  "transport": "stdio"
}

All configs above point at the default data directory. To share memories across clients with a specific project:

{
  "command": "consolidation-memory",
  "env": { "CONSOLIDATION_MEMORY_PROJECT": "my-project" }
}

Every client using the same project name reads and writes to the same database.

Data Storage

All data stays local.

Platform	Path
Linux	~/.local/share/consolidation_memory/projects/<name>/
macOS	~/Library/Application Support/consolidation_memory/projects/<name>/
Windows	%LOCALAPPDATA%\consolidation_memory\projects\<name>\

Roadmap

• Hybrid search (BM25 + semantic fusion)
• Diff-aware merge validation for consolidation
• Query expansion for short/ambiguous recalls
• Recall result deduplication
• Entity extraction and relationship graph
• Entity-aware recall boosting
• First-party plugins (git history, project context, Obsidian export)
