fastmcp

📋 Overview:

This webpage is the GitHub repository page for "fastmcp," a TypeScript framework designed for building Model Context Protocol (MCP) servers. The page provides details about the framework's features, installation, core concepts (tools, resources, prompts), authentication, sessions, and how to run and test a server using `mcp-cli` and `MCP Inspector`. It also showcases projects using FastMCP and acknowledges contributions.

⭐ Key Points:

• FastMCP is a TypeScript framework for building MCP servers.


• It offers features such as tool, resource, and prompt definition, authentication, sessions, image content handling, logging, error handling, and SSE support.


• The framework supports both testing via a CLI tool and debugging through the MCP Inspector web UI.


• FastMCP is inspired by a Python implementation and adopts code from LiteMCP.


🔍 Main Findings:

• FastMCP allows servers to expose executable functions (tools) that can be invoked by clients.


• Resources can be defined to make various types of data (files, images, logs) available to clients.


• Prompts enable the creation of reusable prompt templates for standardized LLM interactions.


• The framework supports custom authentication functions and maintains client session data.


📊 Details:

• Installation is done via npm: `npm install fastmcp`.


• SSE (Server-Sent Events) is supported for real-time communication with clients.


• Tools can report progress updates to the client.


• Resource templates are supported, allowing for dynamic resource URIs with auto-completion for arguments.


• Clients can configure logging levels.


• Servers are tested using the fastmcp dev command.

🎯 Conclusion:
The webpage serves as a comprehensive guide to the FastMCP framework, highlighting its capabilities and providing instructions for its use in building and testing MCP servers. It aims to attract developers interested in creating MCP-compatible services using TypeScript.
