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.

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

npm package @striderlabs/mcp-delta - the @striderlabs scope differs from the repo owner (markswendsen-code); confirm it's the project's official package
