Overview

FastMCP: Build MCP Servers with Python

FastMCP is a high-level Python framework for building Model Context Protocol (MCP) servers - a standardized way to provide context and tools to Large Language Models (LLMs).

Key Features

• Pythonic Interface: Create tools and expose resources with simple decorators
• Minimal Boilerplate: Build functional MCP servers with just a few lines of code
• Complete Protocol Support: Aims to implement the full MCP specification
• Built-in Development Tools: Includes CLI for testing and deployment

Core Capabilities

• Resources: Expose data to LLMs (similar to GET endpoints)
• Tools: Enable LLMs to execute actions (similar to POST endpoints)
• Prompts: Define reusable templates for LLM interactions
• Image Handling: Built-in support for image processing and management

Target Audience

Developers building LLM-powered applications, particularly those working with Claude or other MCP-compatible models. Ideal for teams wanting to quickly expose functionality to LLMs without dealing with low-level protocol details.

Note: Currently under active development alongside the MCP specification.
