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 · container (OCI image) - can be sandboxed away from your filesystem

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

license MIT - declared in the repository

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

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