This repository provides reference implementations and resources for the Model Context Protocol (MCP), enabling Large Language Models (LLMs) to securely access tools and data. It serves developers and researchers looking to integrate LLMs with external services, offering a vast ecosystem of pre-built servers for diverse applications.

How It Works

MCP servers act as bridges, translating LLM requests into specific API calls or actions for various services. Each server is implemented using either the TypeScript or Python MCP SDK, abstracting the complexity of interacting with external tools. This approach allows LLMs to leverage a wide range of functionalities, from database access and file operations to web scraping and cloud service management, in a standardized and secure manner.

Quick Start & Requirements

• TypeScript Servers: npx -y @modelcontextprotocol/server-<server-name>
• Python Servers: uvx mcp-server-<server-name> or pip install mcp-server-<server-name> followed by python -m mcp_server.<server-name>
• Dependencies: Varies by server; some may require specific SDKs, API keys, or local installations (e.g., database clients, cloud CLIs).
• Configuration: MCP servers are typically configured within an MCP client (e.g., Claude Desktop) via a JSON configuration file.

Highlighted Details

• Extensive Server Ecosystem: Features over 300 reference and third-party servers for databases, cloud services, APIs, file systems, and more.
• SDKs: Provides official SDKs in TypeScript and Python for building custom MCP servers.
• Community Driven: A large and active community contributes new servers and maintains existing ones.
• Security Focus: Emphasizes secure, controlled access to tools and data for LLMs.

Limitations & Caveats

Community-developed servers are explicitly marked as untested and to be used at the user's own risk. Some servers may require specific, potentially sensitive, API keys or credentials for operation.
