Create and extend MCP (Model Context Protocol) servers in Python using FastMCP and the official SDK. Covers tools, resources, prompts, STDIO vs HTTP transports, logging rules for STDIO, and production best practices. Use when building or modifying MCP servers in Python, adding tools/resources/prompts, debugging MCP servers, or choosing transport and client config.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# MCP Servers in Python Create and extend MCP servers in Python with FastMCP and the official MCP Python SDK. Based on [MCP Build a server](https://modelcontextprotocol.io/docs/develop/build-server) and [MCP Best Practices](https://mcp-best-practice.github.io/mcp-best-practice/best-practice/). ## When to Use - Building or extending MCP servers in Python - Adding tools, resources, or prompts - Debugging MCP server connection or tool discovery - Choosing transport (stdio vs streamable HTTP) - Configuring clients (Claude Desktop, Cursor) to run the server ## Core Concepts - **Tools**: Functions callable by the LLM (with user approval). Have explicit input/output and side-effect disclosure. - **Resources**: Readable data (files, API responses) the client fetches for context. URI-based. - **Prompts**: Pre-written templates for specific tasks; reduce prompt drift. - **Discovery**: Clients enumerate tools/resources/prompts and get schemas at connect time. - **Transports**: **stdio** for local, per-user processes; **streamable HTTP** for remote, shared services. ## FastMCP Quick Reference …

How to install
mdr add antoinebou12/uml-mcp/mcp-python@sha256:fc8b682b80c31fbeThe line at the top of this page pins the label git:20260925.e474cbe, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
