### Description (declared)

A2A v1.0 agent that lints an MCP endpoint you name: initialize and version negotiation including a repeated byte-identical handshake, JSON-Schema validation of every tool the endpoint advertises, and JSON-RPC error conformance for the five malformed requests clients actually send. Reports what your endpoint answered, stores nothing, needs no key, and runs against a built-in broken fixture when called with no arguments.
