Supabase vs Dbx
Two MCP servers from our database ranking, compared on live data - updated nightly, never sponsored.
Bottom line · 2026-09-18
Supabase records significantly more monthly package installs (462,519 vs 36,211); both are actively maintained, with commits inside the last month.
How they differ in kind
Supabase focuses on: The Model Context Protocol (MCP) standardizes how Large Language Models (LLMs) talk to external services like Supabase. Dbx focuses on: 90+ databases in 25 MB. Desktop, Docker, CLI, built-in AI assistant, and MCP Server. Supabase offers a remote endpoint; Dbx is local stdio. Environment-variable extraction: Supabase yielded no variables extracted; Dbx yielded 2 variables. Implementation languages differ (TypeScript vs Rust).
What each one does
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.
Dbx
90+ databases in 25 MB. Desktop, Docker, CLI, built-in AI assistant, and MCP Server. It runs locally over stdio via the published package.

Which one, for what
Derived from the signals above, not hands-on testing.
Pick Supabase if…
- → you want the more widely installed option - 462,519 monthly installs vs 36,211
- → you want a hosted endpoint instead of running a local process
Pick Dbx if…
- → you prefer a Rust codebase to extend or audit
- → category standing - #3 of 168 maintained database servers

Quick answers
Is Supabase better than Dbx?
Package installs favor Supabase: 462,519 monthly installs to 36,211. Dbx still ranks #3 of 168 maintained database servers. Data as of 2026-09-18; we haven't hands-on tested either.
Can I use Supabase 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?
Supabase: no 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.
