Cpersona MCP Server

Persistent memory for AI agents, over MCP. One SQLite file you own. No LLM in the loop. Honest when recall degrades. It runs locally over stdio via the published package.

People who work with memory, rag and semantic search and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

Set CPERSONA_DB_PATH, EMBEDDING_MODE, EMBEDDING_HTTP_URL, EMBEDDING_PROVIDER before connecting.

Claude Code

claude mcp add cloto-dev-cpersona -- uvx cpersona

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {

      "command": "uvx",
      "args": [
        "cpersona"
      ]

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

pypi package cpersona - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.Cloto-dev is GitHub-verified and matches the repo owner

05 · Cpersona FAQ

What is Cpersona?

Persistent memory for AI agents, over MCP. One SQLite file you own. No LLM in the loop. Honest when recall degrades. It runs locally over stdio via the published package.

Is Cpersona still maintained?

Yes - as of 2026-09-18, its last commit was 2026-09-18. We re-verify nightly.

How do I install Cpersona?

Run `uvx cpersona`. The README documents 4 environment variables (CPERSONA_DB_PATH, EMBEDDING_MODE, EMBEDDING_HTTP_URL…) to set first. Set CPERSONA_DB_PATH, EMBEDDING_MODE, EMBEDDING_HTTP_URL, EMBEDDING_PROVIDER before connecting. You can also paste the ready-made client config above.

Does Cpersona run locally?

Yes - it's a stdio server: it runs on your machine (via uvx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
