Diagram Element Creation With Schema Validated Properties

Draw.io Model Context Protocol (MCP) Server

Unique: Uses zod schema validation to enforce input correctness before WebSocket transmission, preventing invalid diagram operations from reaching the browser extension and reducing round-trip error handling

vs others: Schema validation at the server layer catches errors early and provides clear error messages to LLM clients; faster than trial-and-error approaches where invalid operations are sent to Draw.io and rejected
