A Model Context Protocol (MCP) server that enables LLMs to interact directly with MongoDB databases. Query collections, inspect schemas, and manage data seamlessly through natural language.
## ✨ Features
- 🔍 Collection schema inspection
- 📊 Document querying and filtering
- 📈 Index management
- 📝 Document operations (insert, update, delete)

## 🚀 Quick Start
To get started, find your mongodb connection url and add this configuration to your Claude Desktop config file:
**MacOS**: `~/Library/Application\ Support/Claude/claude_desktop_config.json`
**Windows**: `%APPDATA%/Claude/claude_desktop_config.json`
```json
{
"mcpServers": {
"mongodb": {
"command": "npx",
"args": [
"mongo-mcp",
"mongodb://<username>:<password>@<host>:<port>/<database>?authSource=admin"
]
}
}
}
```
### Installing via Smithery
To install MongoDB MCP Server for Claude Desktop automatically via [Smithery](https://smithery.ai/server/mongo-mcp):
```bash
npx -y @smithery/cli install mongo-mcp --client claude
```
### Prerequisites
- Node.js 18+
- npx
- Docker and Docker Compose (for local sandbox testing only)
- MCP Client (Claude Desktop App for example)
### Test Sandbox Setup
If you don't have a mongo db server to connect to and want to create a sample sandbox, follow these steps
1. Start MongoDB using Docker Compose:
```bash
docker-compose up -d
```
2. Seed the database with test data:
```bash
npm run seed
```
### Configure Claude Desktop
Add this configuration to your Claude Desktop config file:
**MacOS**: `~/Library/Application\ Support/Claude/claude_desktop_config.json`
**Windows**: `%APPDATA%/Claude/claude_desktop_config.json`
#### Local Development Mode:
```json
{
"mcpServers": {
"mongodb": {
"command": "node",
"args": [
"dist/index.js",
"mongodb://root:example@localhost:27017/test?authSource=admin"
]
}
}
}
```
### Test Sandbox Data Structure
The seed script creates three collections with sample data:
#### Users
- Personal info (name, email, age)
- Nested address with coordinates
- Arrays of interests
- Membership dates
#### Products
- Product details (name, SKU, category)
- Nested specifications
- Price and inventory info
- Tags and ratings
#### Orders
- Order details with items
- User references
- Shipping and payment info
- Status tracking
## 🎯 Example Prompts
Try these prompts with Claude to explore the functionality:
### Basic Operations
```plaintext
"What collections are available in the database?"
"Show me the schema for the users collection"
"Find all users in San Francisco"
```
### Advanced Queries
```plaintext
"Find all electronics products that are in stock and cost less than $1000"
"Show me all orders from the user john@example.com"
"List the products with ratings above 4.5"
```
### Index Management
```plaintext
"What indexes exist on the users collection?"
"Create an index on the products collection for the 'category' field"
"List all indexes across all collections"
```
### Document Operations
```plaintext
"Insert a new product with name 'Gaming Laptop' in the products collection"
"Update the status of order with ID X to 'shipped'"
"Find and delete all products that are out of stock"
```
## 📝 Available Tools
