Placeholders to fill from your own secret store: ${api_key}. The registry never accepts secret values.
Quality – / 100 not scored Not scored: fewer than three checks apply, usually because no remote answered a credential-free probe or the server is a local package.
protocol n/a · weight 25
n/a protocol.modern, protocol.stateless, protocol.transport, protocol.list_ttlno remote answered a protocol handshake (not probed yet, unreachable, or local-only)

Tool changes No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.
Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.
Trust 96 / 100 +repository +dns-namespace +website +reachable +uptime-100% +updated-10d-ago
Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed. How it is computed.
Dependencies Dependency graphs from deps.dev; advisories from OSV.dev, including the GitHub Advisory Database and the PyPI Advisory Database; all CC BY 4.0. The graph is what a clean install of this version resolves today; nothing was installed or run. How it is checked.
Tools (0) No tools observed. Tools appear once a credential-free probe can list them.
