Supabase Integration MCP

A Model Context Protocol server that connects agents to your Supabase project — safely.

Tools exposed

sql(query, params) — parameterized queries only
list_tables() / describe_table(name)
select / insert / update with RLS awareness
storage_list(bucket)

Security model

Parameterized SQL only — no string interpolation
Read-only mode — opt-in write access per tool
RLS-aware — respects row-level security policies
Reads SUPABASE_SERVICE_ROLE_KEY from the environment — never logs it
