FastMCP Development Guide

This skill provides comprehensive guidance for building Model Context Protocol (MCP) servers and clients using FastMCP, a fast and Pythonic framework.

Core Concepts

FastMCP simplifies building MCP servers that allow LLMs to interact with your data and services:

• Tools: Functions that LLMs can call to perform actions
• Resources: Data that LLMs can read (files, APIs, databases)
• Prompts: Reusable prompt templates with arguments
• Context: Access to logging, progress reporting, and LLM sampling
• Composition: Combine multiple servers via import/mount/proxy

Installation

pip install fastmcp
