How do I build an MCP server for LLM integration with external APIs?▼

You can build an MCP server using either Python with the FastMCP framework or Node/TypeScript with the official MCP SDK. This guide covers research, implementation, testing, and evaluation phases for both frameworks.

What is the best way to design tools for an MCP server?▼

The best way to design MCP server tools is to ensure they are clear, discoverable, and actionable. This guide emphasizes proper API coverage, tool naming conventions, context management, and actionable error messages for LLMs.

Can I use FastMCP and the TypeScript SDK to create Model Context Protocol servers?▼

Yes, you can use FastMCP for Python development or the TypeScript SDK for Node environments. Both frameworks are fully supported for creating robust Model Context Protocol servers that interact with external services.

How do I test and evaluate an MCP server after implementation?▼

You evaluate an MCP server by creating rigorous evaluations to test its effectiveness. This guide provides an evaluation framework to verify API coverage, tool naming, context management, and actionable error messages.

Does the MCP SDK support managing GitHub issues and pull requests via LLMs?▼

Yes, the MCP SDK supports integrating external services like GitHub. The guide specifically uses building an MCP server to manage GitHub issues and pull requests as a core use case example.
