MCP Reference Servers
Reference MCP server implementations for learning, not production use
The modelcontextprotocol/servers repository holds reference implementations of MCP servers, such as filesystem, Git, fetch, and memory, maintained by the MCP project to demonstrate protocol features. They are examples and starting points rather than production-ready integrations.
Key features
- Filesystem, Git, and fetch servers
- Memory and sequential-thinking servers
- TypeScript and Python examples
- Points to the MCP Registry for production servers
