MongoDB MCP Server — Hosted for Any AI Agent

mcp-mongodb — MongoDB Atlas MCP Server

Query collections, insert documents, and run aggregation pipelines on your MongoDB Atlas database from your AI agents.

MongoDB Atlas is the cloud-hosted version of MongoDB — the most popular document database, used by millions of developers to store flexible JSON-like documents at scale. This MCP server gives your AI agents full CRUD access plus aggregation pipeline support through the Atlas Data API: finding, inserting, updating, and deleting documents across any database and collection in your cluster — all through natural language.

Live endpoint: https://mcp.aerostack.dev/s/aerostack/mcp-mongodb

What You Can Do

• Query any collection in your MongoDB Atlas cluster with filters, sorting, and pagination to pull live data into agent workflows
• Insert, update, or delete documents to write results back to your database as part of automation pipelines
• Run aggregation pipelines to perform complex data transformations, grouping, and analytics directly on your cluster
• List databases and collections to explore your data model and discover available data sources
