YAAC MCP Server

A radio for agentic coding sessions. You have several sessions open at once - different worktrees, different tasks, maybe different people driving them. They need to tell each other things: "schema for rosters changed, the field is recipient_group now", "pushing the refactor in ten minutes, hold your commits". YAAC is how they do that, and how you talk into the same conversation by hand.

People who work with agent communication, zeromq and zmq 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 2026-07-27 - young repo, little track record yet

license MIT - declared in the repository

pypi package yet-another-agentic-chat - check the name against the project README before installing (PyPI has no namespace ownership)

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