Overview

What is MongoDB MCP Server?

A Model Context Protocol (MCP) server for MongoDB databases. It analyzes database collection structures and generates queries using AI, providing two main tools: ERD generation and natural‑language query generation.

How to use MongoDB MCP Server?

Install dependencies (npm install), build (npm run build), then run the server with node dist/index.js "mongodb://localhost:27017". For use with Claude Desktop, configure the MCP server in claude_desktop_config.json pointing to the built index.js and a MongoDB URI.

Key features of MongoDB MCP Server

Generates ERD diagrams (Mermaid or JSON format)
Creates MongoDB queries from natural language descriptions
Analyzes actual database structure for accurate queries
Supports both raw MongoDB and Mongoose query syntax
Optional explanations for generated queries

Use cases of MongoDB MCP Server

Quickly visualize database schema by generating ERD from collections
Let AI write MongoDB queries from plain‑language requests
Explore an unfamiliar database with auto‑generated ERD
Speed up development by prototyping queries without manual MongoDB syntax

FAQ from MongoDB MCP Server

What tools are available in MongoDB MCP Server?

Two tools: generateErd (produces ERD from database collections) and generateQuery (generates MongoDB/Mongoose queries from a natural‑language description).

How do I connect the server to my MongoDB instance?

Pass the MongoDB connection string as a command‑line argument when starting the server, e.g., node dist/index.js "mongodb://localhost:27017".

Can I choose the output format for ERD?

Yes, the format parameter accepts "mermaid" (default) or "json".

Does query generation support Mongoose syntax?

Yes, the type parameter can be set to "mongoose" (default is "mongodb").

What runtime environment is required?

Node.js with npm. The server is built and run locally; a running MongoDB instance must be accessible at the provided URI.
