MCP MongoDB Server is a versatile Model Context Protocol server designed to provide seamless access to MongoDB databases. This innovative server empowers large language models (LLMs) by enabling them to inspect collection schemas and perform various MongoDB operations efficiently.

Key Features

Read-Only Mode

• Safe Connections: Connect to MongoDB in read-only mode using the --read-only or -r flag to prevent any write operations (including updates, inserts, and index creation).
• Optimized Performance: Utilize MongoDB's secondary read preference for enhanced read performance, ensuring safety for production database connections.

Comprehensive Resource Management

• Access and list collections via standard mongodb:// URIs, with each collection offering detailed attributes: name, description, and schema.
• JSON format available for easy schema access.

Powerful Tools for MongoDB Operations

• Query: Execute MongoDB queries with optional execution plan analysis, specifying collection name, filter, projection, and limit, while receiving results or plan details.

  mcp-mongo-server query <collection_name> <filter> <projection>
  

• Aggregate: Perform complex data analysis with MongoDB aggregation pipelines, allowing for detailed input and analysis.

  mcp-mongo-server aggregate <collection_name> <pipeline_stages>
  

• Update: Efficiently update documents within a specified collection, with control over upsert and multi options.

  mcp-mongo-server update <collection_name> <filter> <update>
  

• ServerInfo: Retrieve comprehensive information and status of the connected MongoDB server.

• Insert: Add new documents into collections with specified write options.

• CreateIndex: Easily create indexes to optimize data retrieval.

• Count: Count documents that match a given query for analytical purposes.

Collection Analysis Prompts

Utilize the analyze_collection prompt to gain insights about schema, data types, and statistics related to the structure and contents of a specified collection.

Development Integration

With straightforward setup processes, developers can easily install dependencies, build, and run the server. The MCP MongoDB Server is compatible with various platforms and configurations, including integration with Claude Desktop.

Configuration Example for Claude Desktop

To configure the server to work with the Claude Desktop app, add the following configuration to the claude_desktop_config.json file:

{
  "mcpServers": {
    "mongodb": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-mongo-server",
        "mongodb://user:password@localhost/sample_namespace"
      ]
    }
  }
}

MCP MongoDB Server represents a powerful tool for those seeking to leverage the capabilities of MongoDB within the Model Context Protocol framework, offering extensive functionalities to enhance data accessibility and management.
