supabase

supabase is an MCP server for Cursor from wesselgrift/sveltekit-spa. Its token cost is not measured, scanned A, original, MIT.

A hosted Supabase connection for an agent. Supabase provides hosted Postgres databases, authentication, and related project services, while this connection exposes project, table, SQL, and migration operations in read-only mode.

In plain words
What is it for?
Use it to inspect Supabase projects and tables, review SQL, and examine database migrations.
Why use it?
It gives the agent project and database context without requiring those details to be copied into the conversation. Read-only access also avoids changing the project through this connection.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Security

Grade A, and why

supabase scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
