    Returns connection instructions: how to set the upstream MCP server (X-Prism-Upstream header or ?upstream= query param), the query-param config keys for header-less clients, how destinations and the borrowed-token model work, and example client configs. Start here if you are an agent discovering Prism for the first time.

    Description, as the server wrote it
    Returns Prism's service identity and runtime state: version, transport, public URL, capture default, and the number of MCP sessions currently being traced. Use this to confirm which Prism deployment you are talking to and whether it is healthy before configuring an upstream.

    Why it is in this group

    • The name "prism_ping" says "ping": a word for reading.
    Description, as the server wrote it
    Returns {"pong": true, "time": <unix seconds>} plus an optional echo of the 'echo' argument. Use to verify connectivity through the gateway before pointing it at an upstream MCP server.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
