Reviewer Notes

Supabase Edge Functions are well-documented with a solid REST API for deployment and management, making discovery good for agents. Account creation is possible via API, though email verification may require human intervention. Agent tooling is strong with good SDK support (supabase-js), structured JSON responses, and clear error handling. Reliability is solid with Deno's infrastructure backing it, though edge function execution timeouts (10 seconds) limit complex operations. The free tier provides sufficient quota for agents to experiment, but bandwidth costs at scale and lack of an MCP server are minor limitations for agent integration.
