02 · Evidence

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 2026-08-24 - young repo, little track record yet

license no standard license detected - usage rights unclear; check the repo before commercial use

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

registry namespace io.github.Hannay001 is GitHub-verified and matches the repo owner
