Thread Keeper MCP Server

Multi-agent shared brain across Claude Code/Desktop, Codex, Antigravity CLI (agy), Copilot, and VS Code. Cross-session memory, self-improving skill loops, and inter-agent signaling - one local MCP server turns parallel agent instances into a coordinated multi-agent system instead of N isolated chats.

People connecting memory tools to 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

license MIT - declared in the repository

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

registry namespace io.github.po4erk91 is GitHub-verified and matches the repo owner

What is Thread Keeper?

Is Thread Keeper still maintained?

Yes - as of 2026-08-25, its last commit was 2026-08-24 and it shipped 10+ releases in the last 90 days. We re-verify nightly.

How do I install Thread Keeper?

Run `uvx threadkeeper`. The README documents one environment variable (THREADKEEPER_MEMORY_EGRESS) to set first. Set THREADKEEPER_MEMORY_EGRESS before connecting. You can also paste the ready-made client config above.

Does Thread Keeper 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.
