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

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

npm package @hol-org/hashnet-mcp - the @hol-org scope differs from the repo owner (hashgraph-online); confirm it's the project's official package

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