Placeholders to fill from your own secret store: ${DATABASE_URL}, ${MCP_API_KEY}, ${OPENAI_API_KEY}, ${TWILIO_AUTH_TOKEN}. The registry never accepts secret values.

This is a local package: the command runs on your machine.

Quality – / 100not scored

Not scored: fewer than three checks apply, usually because no remote answered a credential-free probe or the server is a local package.

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.
