To build an MCP server for LLM integration, follow agent-centric design principles and use specific implementation guides for Python (FastMCP) or Node/TypeScript to define external tools. This enables large language models to interact with external services via a standardized protocol.

The best way to design tools for an LLM API gateway is applying agent-centric design principles that optimize for LLM context and workflows. This approach ensures the Model Context Protocol server manages operations like user accounts and order processing effectively.

Yes, this MCP server development guide supports both Python and TypeScript. It provides detailed language-specific implementation instructions using FastMCP for Python and standard Node/TypeScript environments for building LLM-integrated external service tools.

To evaluate the effectiveness of your MCP server, use the provided evaluation framework to create robust evaluations. This tests how well your server enables LLMs to interact with external services and validates the overall tool design and protocol adherence.

You need to implement the Model Context Protocol when building an API gateway for an LLM that requires external service interaction. It provides the necessary protocol adherence for seamless LLM integration with tasks like retrieving product information or processing orders.
