Mnemograph MCP Server

A persistent, event-sourced knowledge graph for AI coding agents. Unlike simple key-value memory, Mnemograph captures entities, relations, and observations - enabling semantic search, tiered context retrieval, and git-based version control of your AI's memory. It runs locally over stdio via the published package.

People connecting memory tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Mnemograph

before you install - you'll need

MEMORY_PATH

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add tm42-mnemograph -- uvx mnemograph

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "tm42-mnemograph": {
      "command": "uvx",
      "args": [
        "mnemograph"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

02 · Evidence

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

registry namespace io.github.tm42 is GitHub-verified and matches the repo owner

03 · Who maintains Mnemograph

05 · Mnemograph FAQ

What is Mnemograph?

Is Mnemograph still maintained?

Yes - as of 2026-08-25, its last commit was 2026-02-14. We re-verify nightly.

How do I install Mnemograph?

Run `uvx mnemograph`. The README documents one environment variable (MEMORY_PATH) to set first. You can also paste the ready-made client config above.

Does Mnemograph 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.
