Overview

What is Mongo Mcp?

Mongo Mcp is a Model Context Protocol (MCP) service that provides a comprehensive set of tools for Large Language Models (LLMs) to interact with MongoDB databases. It supports complete CRUD operations, administrative tasks, and advanced features like aggregation and index management. It is designed for developers who want to enable AI assistants to manage and query MongoDB instances through a standardized MCP interface.

How to use Mongo Mcp?

Run the server directly with uvx run mongo-mcp (requires Python 3.10+, a running MongoDB, and the uv package manager). Configure connection via environment variables such as MONGODB_URI (default mongodb://localhost:27017). The server uses stdio transport, so it integrates with any MCP client that supports that transport, e.g., Cursor by adding a JSON configuration to .cursor/mcp.json.

Key features of Mongo Mcp

  • Full database and collection management tools
  • Document CRUD with batch operations
  • Index management including text and compound indexes
  • Aggregation pipeline and distinct value queries
  • Monitoring and admin tools (server status, replica set)
  • Configurable connection pooling, timeouts, and security

Use cases of Mongo Mcp

  • Using an LLM-powered code editor to query and update MongoDB collections
  • Automating database administration tasks through natural language prompts
  • Building AI assistants that can create, drop, or rename databases and collections
  • Enabling LLMs to run aggregation pipelines and analyze data in MongoDB

Frequently asked questions

1

What dependencies does Mongo Mcp require?

Python 3.10 or above, a running MongoDB database service, and it is recommended to use [uv](https://github.com/astral-sh/uv) to run the program.

2

How do I connect to a MongoDB instance?

Set the `MONGODB_URI` environment variable to your MongoDB connection string (default `mongodb://localhost:27017`). You can optionally set `MONGODB_DEFAULT_DB` for the default database.

3

Is there any security or TLS support?

Yes. You can enable TLS by setting `MONGODB_TLS_ENABLED` to `true`, and configure authentication via `MONGODB_AUTH_SOURCE`, `MONGODB_AUTH_MECHANISM`, etc.

4

Can I enable dangerous administrative operations?

Yes. Set `ENABLE_DANGEROUS_OPERATIONS` to `true` (default `false`). Administrative operations are enabled by default (`ENABLE_ADMIN_OPERATIONS` defaults to `true`).

5

What transport method does the server use?

The server uses the stdio transport method, making it suitable for integration with MCP clients that support this transport method, such as Cursor.
