We auto-extract tools from the README. The maintainer can list them under a ## Tools heading to populate this section.

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

Frequently asked questions

1

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).

2

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"`.

3

Can I choose the output format for ERD?

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

4

Does query generation support Mongoose syntax?

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

5

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.
