mcp-mongo-server

This MCP server connects your AI assistant to MongoDB. Run queries, inspect collections, check indexes, and explore your data without switching to Compass or the shell. Point it at a connection string and go.

Community-maintained. Setup requires your MongoDB connection string in the config. Works with local instances, Atlas, and self-hosted deployments. No additional API keys beyond your existing database credentials.

Install this if MongoDB is your primary database and you want your assistant to query it directly. Saves time on ad-hoc data exploration and debugging. The catch: community project with a single maintainer. Write operations exist, so be careful with permissions on production databases.
