MongoDB MCP Server vs Dbx

Two MCP servers from our database ranking, compared on live data - updated nightly, never sponsored.

Bottom line · 2026-08-25

MongoDB MCP Server records significantly more monthly package installs (450,845 vs 33,367); both are actively maintained, with commits inside the last month.

How they differ in kind

MongoDB MCP Server focuses on: A Model Context Protocol server for interacting with MongoDB Databases and MongoDB Atlas. Dbx focuses on: 90+ databases in 20 MB. Desktop, Docker, CLI, built-in AI assistant, and MCP Server. Environment-variable extraction: MongoDB MCP Server yielded 4 variables; Dbx yielded 2 variables. Implementation languages differ (TypeScript vs Rust).

Quick answers

Is MongoDB MCP Server better than Dbx?

Package installs favor MongoDB MCP Server: 450,845 monthly installs to 33,367. Dbx still ranks #4 of 151 maintained database servers. Data as of 2026-08-25; we haven't hands-on tested either.

Can I use MongoDB MCP Server and Dbx together?

Yes - MCP clients accept multiple servers in one config, so you can enable both database servers side by side. If their tools overlap, keep the one whose toolset fits to keep your agent's tool list lean.

What environment variables do their READMEs document?

MongoDB MCP Server: 4 environment variables extracted from the README setup; Dbx: 2 environment variables extracted from the README setup. Extraction does not rule out other authentication or configuration steps; check each project's current documentation.
