The MCP revision dated 2026-07-28 is the largest breaking change in the protocol's history — stateless transport, OAuth 2.1, deprecated capabilities. mcp-migration-check points at a running endpoint (or scans a repo) and reports, with a letter grade and per-finding fixes, exactly what breaks. Deterministic — no LLM, no API key, nothing stored.

Four surfaces over one rule engine: web demo · CLI (npx mcp-migration-check <url>) · GitHub Action · agent skill. Ships with an ecosystem report covering 13,350 probed endpoints from the official MCP registry.
