📋 Overview

This MCP server implementation provides a robust interface for interacting with MongoDB databases through the Model Context Protocol. It supports operations on databases, collections, and documents with proper async/await patterns and error handling.

✨ Features

• 🔄 Full MongoDB CRUD operations support
• 🔐 Secure connection handling with MongoDB Atlas
• 🚦 Async/await patterns for optimal performance
• 🛡️ Comprehensive error handling
• 📦 Docker support for easy deployment
• 🔍 Query execution with proper type hints

🚀 Quick Start

Using uvx (Python)

# Run directly with uvx
uvx mongodb-mcp-bridge

# With SSE transport for remote connections
uvx mongodb-mcp-bridge --transport=sse

Using npx (Node.js)

# Run directly with npx
npx mongodb-mcp-bridge

# With SSE transport for remote connections
npx mongodb-mcp-bridge --transport=sse

Environment Variables

Set these environment variables before running the server:

# Required
MONGODB_URI="your_mongodb_connection_string"

# Optional
MONGODB_DB="default_database_name"
MCP_PORT="6274"  # Default port for MCP Inspector

Using Docker 🐳

# Build the Docker image
docker build -t mongodb-mcp-server .

# Run the container
docker run -e MONGODB_URI="your_mongodb_uri" -p 6274:6274 mongodb-mcp-server

🔗 IDE Integration

VS Code Setup

Add this to your VS Code settings.json:

{
  "mcp": {
    "inputs": [
      {
        "type": "promptString",
        "id": "mongodbUri",
        "description": "MongoDB Connection URI"
      }
    ],
    "servers": {
      "mongodb": {
        "command": "uvx",
        "args": ["mongodb-mcp-bridge", "--transport=sse"],
        "env": {
          "MONGODB_URI": "$(mongodbUri)"
        }
      }
    }
  }
}

Cursor/Windsurf Setup

For Cursor or Windsurf, configure the MCP server with:

{
  "mcp": {
    "servers": {
      "mongodb": {
        "url": "http://localhost:6274"
      }
    }
  }
}

📚 Available Tools

1. ping

   • Quick connection test to verify MongoDB connectivity

2. list_databases

   • List all available databases in the MongoDB instance

3. find_documents

   • Query documents in a collection with filtering options
   • Parameters:
     • database: Database name
     • collection: Collection name
     • query: MongoDB query object (optional)
     • limit: Maximum number of documents to return (default: 10)

🔍 Example Usage

Using the MCP Inspector (http://127.0.0.1:6274):

// List all databases
{
    "tool": "list_databases"
}

// Find documents in a collection
{
    "tool": "find_documents",
    "database": "your_database",
    "collection": "your_collection",
    "query": {"status": "active"},
    "limit": 5
}
