Summary

Supabase introduced a feature enabling applications to run their own Model Context Protocol server. Customers sign in using their existing credentials so tool calls execute under their identity, enforcing Row Level Security policies. Developers can install the block and let external AI clients interact directly with application data and workflows.

What changed

  • Added an MCP Server block that copies an Edge Function into supabase/functions/mcp for handling requests and authentication.
  • Used Supabase Auth to handle OAuth flows and carry user identity into every tool call.
  • Enabled Row Level Security enforcement by supplying handlers with the signed-in user's Supabase client.
  • Integrated support for MCP Apps to display app UI components inside chat interfaces like ChatGPT.

Availability

Founder takeaway

If you build on Supabase, install the new MCP server block to let users run your app actions directly from clients like Claude and ChatGPT while preserving your RLS security policies.
