Building a Type-Safe MCP Server in TypeScript for Enterprise Data Access
TechTarget, Tuesday, August 19th, 2025
Production MCP servers require workflow-based design, schema validation, and integration testing beyond basic API wrapping.
Building a production-ready MCP server means treating it as an integration service rather than a simple API wrapper.
The article recommends Zod schemas for unified input validation and TypeScript types, read-only defaults with explicit mutation controls, and workflow-based tools instead of mirroring low-level GraphQL operations.
Security considerations include rate limiting per intent and mitigating prompt injection through narrow schemas. Real integration testing against production backends proved essential, since mocked tests cannot verify that generated requests actually work with live APIs and resolvers.
