This page showcases various Model Context Protocol (MCP) servers that demonstrate the protocol’s capabilities and versatility. These servers enable Large Language Models (LLMs) to securely access tools and data sources.

​
Reference implementations

These official reference servers demonstrate core MCP features and SDK usage:

​
Current reference servers

  • Everything - Reference / test server with prompts, resources, and tools
  • Fetch - Web content fetching and conversion for efficient LLM usage
  • Filesystem - Secure file operations with configurable access controls
  • Git - Tools to read, search, and manipulate Git repositories
  • Memory - Knowledge graph-based persistent memory system
  • Sequential Thinking - Dynamic and reflective problem-solving through thought sequences
  • Time - Time and timezone conversion capabilities

Getting started

​
Using reference servers

TypeScript-based servers can be used directly with npx: 
npx -y @modelcontextprotocol/server-memory
Python-based servers can be used with uvx (recommended) or pip: 
# Using uvx uvx mcp-server-git  # Using pip pip install mcp-server-git python -m mcp_server_git

​
Configuring with Claude

To use an MCP server with Claude, add it to your configuration: 
{  "mcpServers": {  "memory": {  "command": "npx",  "args": ["-y", "@modelcontextprotocol/server-memory"]  },  "filesystem": {  "command": "npx",  "args": [  "-y",  "@modelcontextprotocol/server-filesystem",  "/path/to/allowed/files"  ]  },  "github": {  "command": "npx",  "args": ["-y", "@modelcontextprotocol/server-github"],  "env": {  "GITHUB_PERSONAL_ACCESS_TOKEN": "<YOUR_TOKEN>"  }  }  } }
