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 no standard license detected - usage rights unclear; check the repo before commercial use
pypi package mcpsafetywarden - check the name against the project README before installing (PyPI has no namespace ownership)
registry namespace io.github.gautamvarmadatla is GitHub-verified and matches the repo owner
