MCP Reference Servers

What it does

This repository holds reference implementations of MCP servers. They show how the protocol works and cover basic jobs such as file access, Git, fetching web pages and a simple knowledge-graph memory.

Why it is useful

• Small, readable servers: a good place to learn MCP.
• Useful building blocks that you can run as they are.

How to use it

Each server has its own folder and command, for example:

npx -y @modelcontextprotocol/server-memory
uvx mcp-server-git

Watch out for

• They are references, not hardened products. To find more servers, use the official MCP Registry.
