🗄️ MongoDB MCP Server for LLMS

A Model Context Protocol (MCP) server that enables LLMs to interact directly with MongoDB databases. Query collections, inspect schemas, and manage data seamlessly through natural language.

📚 What is Model Context Protocol (MCP)?

The Model Context Protocol (MCP) is an open standard developed by Anthropic that creates a universal way for AI systems to connect with external data sources and tools. MCP establishes a standardized communication channel between:

• MCP Clients: AI assistants like Claude that consume data (e.g., Claude Desktop, Cursor.ai)
• MCP Servers: Services that expose data and functionality (like this MongoDB server)

Key benefits of MCP:

• Universal Access: Provides a single protocol for AI assistants to query data from various sources
• Standardized Connections: Handles authentication, usage policies, and data formats consistently
• Sustainable Ecosystem: Promotes reusable connectors that work across multiple LLM clients

✨ Features

• 🔍 Collection schema inspection
• 📊 Document querying and filtering
• 📈 Index management
• 📝 Document operations (insert, update, delete)
• 🔒 Secure database access through connection strings
• 📋 Comprehensive error handling and validation

📋 Prerequisites

Before you begin, ensure you have:

• Node.js (v18 or higher)
• MongoDB instance (local or remote)
• An MCP client like Claude Desktop or Cursor.ai

You can verify your Node.js installation by running:

node --version  # Should show v18.0.0 or higher

🚀 Quick Start

To get started, find your MongoDB connection URL and add this configuration to your Claude Desktop config file:

MacOS: ~/Library/Application\ Support/Claude/claude_desktop_config.json
Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "mongodb": {
      "command": "npx",
      "args": [
        "mongo-mcp",
        "mongodb://:@:/?authSource=admin"
      ]
    }
  }
}
