MongoDB MCP Server vs Supabase
Two MCP servers from our database ranking, compared on live data - updated nightly, never sponsored.
Bottom line · 2026-08-25
monthly package install counts are comparable (450,845 vs 374,748); 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. Supabase focuses on: The Model Context Protocol (MCP) standardizes how Large Language Models (LLMs) talk to external services like Supabase. Supabase offers a remote endpoint; MongoDB MCP Server is local stdio. Environment-variable extraction: MongoDB MCP Server yielded 4 variables; Supabase yielded no variables extracted.
What each one does
MongoDB MCP Server
A Model Context Protocol server for interacting with MongoDB Databases and MongoDB Atlas. Its 40 documented tools cover atlas, collection, many, cluster. It runs locally over stdio via the published package.
From the project's README.
Supabase
The Model Context Protocol (MCP) standardizes how Large Language Models (LLMs) talk to external services like Supabase. It connects AI assistants directly with your Supabase project and allows them to perform tasks like managing tables, fetching config, and querying data. See the full list of tools.
From the project's README.

Which one, for what
Derived from the signals above, not hands-on testing.
Pick MongoDB MCP Server if…
- → its documented toolset fits - 40 tools including aggregate, aggregate-db
- → measured package adoption matters - 450,845 monthly installs
Pick Supabase if…
- → release velocity matters - 10+ releases in 90 days vs 3
- → you want a hosted endpoint instead of running a local process

Quick answers
Is MongoDB MCP Server better than Supabase?
The numbers don't separate them: 450,845 vs 374,748 monthly installs, and both committed within the last month. Choose on fit - execution model, extracted environment variables, endpoint authentication, and license are in the table above. Data as of 2026-08-25.
Can I use MongoDB MCP Server and Supabase 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; Supabase: no environment variables extracted from the README setup. Extraction does not rule out other authentication or configuration steps; check each project's current documentation.
