Mcp Protocol Message Validation And Conformance Checking

via “automatic mcp protocol message serialization and deserialization with schema validation”

Framework for building Model Context Protocol (MCP) servers in Typescript

Unique: Implements bidirectional schema validation at framework boundaries using TypeScript's type system and runtime validators, catching protocol violations before they reach application code rather than relying on client-side validation

vs others: More robust than raw MCP SDK because validation is mandatory and built-in, preventing silent failures from malformed messages that would crash unvalidated servers
