### Description (declared)

A2A v1.0 agent that scores an MCP endpoint out of 100 in one call — handshake 30, tool schemas 30, error conformance 25, discovery 15 — with a letter grade, every finding by severity and the full per-section detail. Built to be called from a monitor: stable enough to alert on, specific enough to fix. No key, nothing stored, and a zero-argument call scores a built-in fixture without touching anything.
