  Agent Disco publishes an MCP descriptor at /.well-known/mcp.json (protocolVersion 2025-03-26, three tools
  with inputSchema) but ships NO MCP server: the descriptor's own note says the tools "are currently exposed
  over plain HTTP at https://agentdisco.io/api/v1" and that "a native JSON-RPC MCP endpoint is on the
  roadmap". /mcp and /.well-known/mcp return 404 and the official MCP registry has no entry for agentdisco
  (searched 2026-09-19). The tool list below is the provider's own, copied from the descriptor - not derived
  by API Evangelist - but status stays candidate because nothing an MCP client can connect to exists. Each
  tool is bound to its backing REST operation in agentdisco-io-tool-crosswalk.yml.

  note: >-
    No tools/list probe was possible because no JSON-RPC endpoint is advertised or discoverable; the
    descriptor is a capability advertisement that bridges to the REST API.
