What signature algorithms does this server support?

The Passage Protocol supports Ed25519 and P-256 (ECDSA) signatures for cryptographic verification of departure and admission records. Both are industry-standard algorithms suitable for agent authentication and audit logging.

How do I install and run this MCP server?

Install via npm with `npx @cellar-door/mcp-server@0.1.7`. The server communicates over stdio transport, so configure your MCP client to spawn the process and pipe messages through standard input/output.

What are departure and admission records used for?

Departure records log when an AI agent leaves or completes a task; admission records log when an agent enters or starts a session. Together they create a verifiable, signed audit trail of agent lifecycle events.

Can I query records by time range or agent identity?

The registry metadata indicates support for querying departure and admission records, though specific query parameters should be confirmed in the server's API documentation or by testing with your MCP client.

Is this server suitable for compliance and audit requirements?

Yes—cryptographic signatures (Ed25519/P-256) and structured record-keeping make this suitable for compliance scenarios where you need non-repudiation and verifiable agent activity logs.
