Supabase

Developer Tools

Supabase's official MCP server for database management, Edge Functions, branching, and project administration.

Provides full Supabase platform access including SQL execution, migration management, database branching (create/merge/rebase/reset), Edge Function deployment, project lifecycle (create/pause/restore), TypeScript type generation, log retrieval, security advisory checks, and documentation search.

Adding Supabase provisions three things in your zone: an upstream resource pointing at https://mcp.supabase.com/mcp (kept inside Keycard), a Keycard MCP Gateway URL - the downstream resource - that you install in Cursor, Claude Code, or any MCP client, and a provider for token exchange with Supabase’s OAuth issuer.

When your AI client makes a tool call, it sends a Keycard-issued access token to the gateway URL. Keycard’s STS exchanges that token for an upstream Supabase token, the gateway calls the upstream MCP, and the response is proxied back. Your zone’s identity provider, access policies, and audit log apply to every call - the upstream credential never leaves Keycard. Each call is recorded in the audit log with the user identity, the resource accessed, and the policy decision.
