Building an MCP server involves using the TypeScript or Python SDKs to define tools, enforce strict Zod or Pydantic schemas, and configure stdio or streamable HTTP transports for LLM interaction.

The best way to structure tool registration is to enforce strict input/output schemas, apply clear tool annotations, implement pagination, and use comprehensive error handling to ensure production readiness for LLM interactions.

Yes, you can use streamable HTTP transport instead of stdio. The MCP server framework supports both local stdio and remote streamable HTTP transports to enable LLMs to interact with external services via well-structured tools.

Yes, the MCP server framework supports both Zod and Pydantic for input validation. It enforces strict input and output schemas using these libraries to ensure robust tool registration and API client interactions.

Stdio transport for MCP servers is limited to local communication scenarios, whereas remote streamable HTTP transport is required for external service interactions, though both require robust error handling and strict schema enforcement.
