MCP Migration · alpayc bundle Diagnose and carry out the migration of an MCP server to the 2026-07-28 specification — the revision that made the transport stateless, formalized OAuth 2.1, and deprecated the logging, sampling, and roots capabilities. Use this skill whenever someone mentions migrating, upgrading, or checking an MCP server against the 2026-07-28 spec; asks whether their MCP server still works, is "ready", or will break; mentions the stateless transport model, Mcp-Session-Id, or OAuth 2.1 for MCP; or is debugging an MCP server that stopped working after a spec or SDK bump. Also use it when someone asks you to review or audit MCP server code for compatibility, even if they don't name the spec date.
