Building an MCP server requires guiding through research, planning, implementation, testing, and evaluation phases. This process supports Python (FastMCP) and Node/TypeScript (MCP SDK) frameworks to ensure reliable LLM interaction with external APIs.

The best way to implement Model Context Protocol servers in Python is using the FastMCP framework. It enforces best practices for tool design, response formatting, pagination, and security while enabling LLMs to reliably query external services and APIs.

Yes, you can use the TypeScript SDK to create an MCP server. The development framework supports both Node/TypeScript (MCP SDK) and Python (FastMCP) for implementing tools, enforcing naming conventions, and creating evaluations for effective LLM usage.

MCP server development explicitly supports pagination and security best practices. The implementation phase enforces naming conventions, response formatting, and security protocols to ensure robust and reliable interactions between LLMs and external APIs.

To evaluate an MCP server and ensure an LLM can use it effectively, you create specific evaluations during the development cycle. This evaluation phase tests the implemented tools for search and retrieval, verifying reliable interaction between the LLM and the server.
