Compartment MCP Server

Encrypted, fully offline memory for AI agents. One vault on your own computer, read and written by Claude Code, Claude Desktop, Hermes Agent, OpenClaw, Cursor, Codex and any other MCP client. No API key, no account, no network, no telemetry. It runs locally over stdio via the published package.

People who work with encryption, vector database and agent memory and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

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

repo age created 2026-07-20 - young repo, little track record yet

license Apache-2.0 - declared in the repository

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

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

Latest releases

v4.10.0 · 2026-09-16

Newer memories now outrank older ones, and a memory ages by how much of the vault has been written since it rather than by the calendar: two weeks old means almost nothing in a quiet vault and a great deal in a busy one.

v4.9.6 · 2026-09-06

A RAM release. Every agent's MCP server used to carry its own copy of the encoder, and the encoder never gave memory back. Now the model runs once per machine, and the encoder stays small whatever it is asked to embed.…

v4.9.5 · 2026-09-03

A docs-and-packaging release: Compartment is now a Gemini CLI extension, and the README carries one-click install buttons for every client that has them. · Gemini CLI extension · gemini-extension.json at the repository…
