MongoDB MCP

Overview

MongoDB MCP provides direct access to MongoDB databases, enabling AI agents to query, analyze, and manage MongoDB collections. Ideal for database debugging, data exploration, and building MongoDB-powered features.

Features

  • CRUD Operations: Insert, find, update, and delete documents
  • Aggregation Pipeline: Run complex aggregation queries
  • Schema Analysis: Explore collection structures and indexes
  • Database Management: List databases, collections, and documents
  • Query Building: Natural language to MongoDB query conversion

Installation

npx -y @modelcontextprotocol/server-mongodb mongodb://localhost:27017

Configuration

Add to your Claude Desktop config:

{
  "mcpServers": {
    "mongodb": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-mongodb", "mongodb://localhost:27017"]
    }
  }
}

For MongoDB Atlas:

{
  "mcpServers": {
    "mongodb": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-mongodb", "mongodb+srv://username:password@cluster.mongodb.net/"]
    }
  }
}
