MCP WireCheck — AgentToolbox
Need to inspect MCP discovery on your workers.dev endpoint?
Check MCP discovery and tools/list on your public workers.dev endpoint.
Choose for anonymous discovery and tools/list on a public workers.dev endpoint you own or are authorized to inspect. Use the bounded compatibility matrix; it never calls a tool or certifies security.
Success: At least one decisive compatible/incompatible wire-shape verdict. Authentication, blocking, unsupported versions and unknown outcomes alone are nonchargeable. No tools/call; not conformance or security certification.
Failure policy: Invalid input, failed criterion or unavailable decisive evidence never settles. Uncertain settlement requires reconciliation; never issue a replacement authorization.
