Building robust AI tools that effectively integrate with external services can be complex and time-consuming. This skill provides a comprehensive guide and best practices to streamline the development of high-quality Model Context Protocol (MCP) servers, ensuring LLMs can interact with your services seamlessly.
I want to build a new MCP server in Python. Guide me through the initial planning and research phase.

MCP servers act as intermediaries that expose your external services as tools for LLMs. Design involves planning the service integration, defining tool schemas with explicit input validation (Pydantic or Zod), writing descriptive metadata, and handling errors and pagination. This skill covers end-to-end design for both Python FastMCP and Node/TypeScript MCP SDK implementations.
Both approaches follow the same core principles but use language-specific frameworks: Python uses FastMCP for rapid development with Pydantic validation, while Node/TypeScript uses the MCP SDK with Zod schemas. This skill provides tailored best practices for each, including tool naming, input validation, multi-format responses, and transport options like stdio, SSE, and HTTP.
Use the evaluation harness included in this skill to create and run tests that verify your tools work effectively with LLMs. Evaluation covers functional requirements (tool naming, input schemas, descriptive metadata), technical requirements (error handling, pagination, character limits), and real-world workflow integration across both Python and TypeScript implementations.
Yes. MCP servers connect internal APIs to AI assistants by exposing API functionalities as LLM-accessible tools. Plan your server to handle API integration, input validation, error management, and pagination. The skill guides you through designing, building, and evaluating an MCP server for your specific use case, such as integrating a CRM with an AI assistant.
Production tools require explicit input schemas (Pydantic for Python, Zod for TypeScript), comprehensive error handling, and clear descriptive metadata. This skill covers validation patterns, error recovery strategies, pagination controls for large datasets, character-limited outputs, and transport-specific considerations to ensure robust LLM-service integration.
No. This skill provides separate best-practice guides for either Python or TypeScript implementations. Choose FastMCP for Python-based development or the MCP SDK for Node/TypeScript. Core concepts like tool design, API integration, and evaluation apply to both, so you can focus on your preferred language.
