description: Guide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services

whether in Python (FastMCP) or Node/TypeScript (MCP SDK).

This document provides Python-specific best practices and examples for implementing MCP servers using the MCP Python SDK. It covers server setup

- [ ] Tools enable complete workflows

* This server provides tools to interact with Example API

const data = await apiRequest(params.limit

content: [{ type: text

textContent = JSON.stringify(output

│ └── constants.ts # Shared constants (API_URL

- **DO NOT use**: Old deprecated APIs such as `server.tool()`

content: [{ type: text

After inspecting the content

<question>Look for pull requests that modified files in the /api directory and were merged between January 1 and January 31

- Goal: identify specific content (e.g.

After understanding the API and tools

- Look at old content (e.g.

return { content: [{ type: text

- Store API keys in environment variables

- **Python**: `{service}_mcp` (e.g.

Prioritize comprehensive API coverage. List endpoints to implement

- [🐍 Python Guide](./reference/python_mcp_server.md) - Module organization

- **Language**: TypeScript (high-quality SDK support and good compatibility in many execution environments e.g. MCPB. Plus AI models are good at generating TypeScript code

Review the service's API documentation to identify key endpoints

Balance comprehensive API endpoint coverage with specialized workflow tools. Workflow tools can be more convenient for specific tasks
