Mongo Mcp

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.

• Enabling LLMs to run aggregation pipelines and analyze data in MongoDB

FAQ from Mongo Mcp

What dependencies does Mongo Mcp require?

Python 3.10 or above, a running MongoDB database service, and it is recommended to use uv to run the program.

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.

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.

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

What transport method does the server use?
