MCP Servers — RAG & Memory

This repository contains reference implementations of Model Context Protocol (MCP) servers, demonstrating how to give LLMs secure, controlled access to tools and data sources. It is intended for developers building their own MCP servers, serving as educational examples rather than production-ready solutions.

✨ Key features

Reference servers for MCP features and SDKs
Includes servers for filesystem, git, memory, time, and more
Supports multiple SDKs: Python, TypeScript, Go, etc.
Easy to run with npx or uvx
Configurable with MCP clients like Claude Desktop

🎯 Use cases

Learning how to implement MCP servers
Providing LLMs with file system access
Enabling LLMs to read and manipulate Git repositories
Adding persistent memory via knowledge graphs
Fetching and converting web content for LLM use

📦 Installation

🧰 Requirements: Requires Node.js (for npx) or Python with uv/pip, and an MCP client for integration.

To use TypeScript-based servers, run with npx:

npx -y @modelcontextprotocol/server-memory

For Python-based servers, use uvx or pip:

With uvx

uvx mcp-server-git

With pip

pip install mcp-server-git
python -m mcp_server_git

Install uv/uvx from here and pip from here.

🚀 Usage

Configure an MCP client, e.g., Claude Desktop, to use a server:

{
  "mcpServers": {
    "memory": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-memory"]
    }
  }
}

On Windows, wrap npx with cmd /c:

{
  "mcpServers": {
    "memory": {
      "command": "cmd",
      "args": ["/c", "npx", "-y", "@modelcontextprotocol/server-memory"]
    }
  }
}

⚠️ Good to know

The servers are reference implementations for educational purposes, not production-ready; developers must evaluate security requirements for their own use cases.

❓ FAQ

Are these servers production-ready?

No, they are reference implementations meant to demonstrate MCP features and SDK usage, not for production use.

How do I run a TypeScript-based server?

Use npx, for example: npx -y @modelcontextprotocol/server-memory

How do I run a Python-based server?

Use uvx or pip, for example: uvx mcp-server-git or pip install mcp-server-git && python -m mcp_server_git

Where can I find more MCP servers?

Browse the MCP Registry at https://registry.modelcontextprotocol.io/ for published servers.
