Exomem MCP Server

Durable memory with sources, proof, history, and review for MCP-capable agents. exomem turns an owned Markdown/Obsidian vault into a local knowledge substrate for Codex, Claude Code, Cursor, chatbots, CLI agents, and any client that can call MCP tools. Your files stay plain, local, portable, and editable outside the server.

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

01 · Install Exomem

before you install - you'll need

EXOMEM_VAULT_PATH is optional or environment-specific per the README.

Claude Code

claude mcp add artexis10-exomem -- uvx exomem

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "artexis10-exomem": {
      "command": "uvx",
      "args": [
        "exomem"
      ]
    }
  }
}

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

Using another client? Same JSON, different key

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 AGPL-3.0 - declared in the repository

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

registry namespace io.github.Artexis10 is GitHub-verified and matches the repo owner

06 · Exomem FAQ

What is Exomem?

Is Exomem still maintained?

Yes - as of 2026-09-18, its last commit was 2026-09-16 and it shipped 10+ releases in the last 90 days. We re-verify nightly.

How do I install Exomem?

Run `uvx exomem`. The README documents one environment variable (EXOMEM_VAULT_PATH) to set first. EXOMEM_VAULT_PATH is optional or environment-specific per the README. You can also paste the ready-made client config above.

Does Exomem 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.
