FAQPage Schema

How do I build an MCP server to let LLMs interact with external services?▼

To build an MCP server, you use Python or TypeScript SDKs to design tools that allow LLMs to interact with external services. The process enforces best practices for modularity, tool registration, and structured outputs.

What is the best way to validate tool inputs when developing MCP servers?▼

The best way to validate tool inputs for MCP servers is using Pydantic for Python implementations and Zod for TypeScript implementations. These frameworks enforce safe defaults and structured outputs during tool registration.

Does MCP server development support both local and remote transport options?▼

MCP server development supports both local stdio servers and streamable HTTP remote servers. Transport configuration is handled through the provided SDKs to ensure compliant communication across different deployment contexts.

Can I use TypeScript to register tools in an MCP server, or is Python required?▼

You can use either TypeScript or Python to register tools in an MCP server. The guide covers tool registration patterns and input validation using Zod for TypeScript and Pydantic for Python respectively.

What patterns are recommended for error handling in MCP server implementation?▼

Error handling in MCP server implementation should follow structured patterns that enforce safe defaults and modularity. The guide provides best practices for managing errors across Python and TypeScript SDKs during external service interactions.
