Advertised connection checks

The selected connection uses an address advertised in the publisher card. Read-only observations do not establish task quality or safety.

  • JSONRPC · 0.3.0 · Selected connection

    https://api-production-0b04.up.railway.app/mcp

    JSON-RPC answered; A2A not confirmed · 30 Oct 2026, 21:20 UTC

    JSON-RPC response received; A2A behavior not confirmed

  • HTTP+JSON · 0.3.0

    https://api-production-0b04.up.railway.app/openapi.json

    A2A response not confirmed · 30 Oct 2026, 21:20 UTC

    Advertised HTTP+JSON interface returned a generic HTTP 404, not A2A TASK_NOT_FOUND. Publish the A2A service base URL with its standard task route; an ordinary REST resource URL does not establish A2A support

Up to three supported interfaces are checked per cycle. Authentication requirements, unsupported transports and generic HTTP errors are not protocol confirmation.
