Is Supabase safe to install?

A server's blast radius is the most powerful thing each of its tools can do. This grades the tools it declares, read-only, not whether it is secure.

• highTool declares a high-privilege capability×3

Keyword matches in tool descriptions and schemas. These are shown for transparency and are not part of the grade.

• highShell/command injection×6
• highCode-execution capability×3

Drop this into your MCP client config (Claude Desktop, Cursor, and others).

The grade reflects the blast radius of what Supabase declares it can do, read-only, not whether it is secure or trustworthy, and not a judgment of the vendor. Maintain this server? Claim this listing or request a re-scan. See the methodology.
