Fixed
- MCP server now conforms to JSON-RPC 2.0: notifications (messages without an
id) never receive a response. Previously,notifications/initialized— which Claude Code sends after every handshake — triggered a spuriousMethod not founderror frame, causing strict MCP clients to mark the server failed on/mcpreconnect after the initial connection.
