Local Memory MCP
Persistent local memory for Claude, Cursor, Codex
21 MCP tools, SQLite + FTS5 + Knowledge Graph. No cloud, no API keys. One command: npx @studiomeyer/local-memory-mcp.
What it solves
Your assistant forgets everything the moment the chat window closes. Every new session starts with you re-explaining the same project, the same decisions, the same people. local-memory-mcp keeps that context in a single SQLite file on your own machine, so the next session begins where the last one ended. Nothing leaves your computer, and there is no account to create.
How it works
Search is hybrid. SQLite FTS5 with BM25 ranking is fused with on-device vector cosine through Reciprocal Rank Fusion, which bridges vocabulary gaps: a search for send also finds publish. It works across German, English, Spanish and a hundred other languages because the embedding model is multilingual and runs locally. If the vector extension cannot load on your machine, search quietly falls back to keyword-only and nothing breaks, you just lose the semantic half. On top of that sit a knowledge graph of entities and relations, a duplicate gatekeeper, bi-temporal queries that answer what you knew on a given date, and a contradiction scanner that needs no language model at all.
When to use it
Take this one if you work on a single machine and want your memory to stay there. It installs with one npx line in Claude Code, or as a double-click bundle in Claude Desktop for Linux, macOS and Windows. No API keys, no signup, no paid tier: 25 tools, MIT licensed, free forever.
When not to use it
It does not sync across devices and it does not serve several agents at once. If you need either, the hosted StudioMeyer Memory is the sibling built for that, with 56 tools and cross-encoder reranking on the same ideas. Switching later costs nothing: the export produces an envelope that imports straight into the hosted tier, so your whole memory comes with you.
