Overview

Supabase in your warehouse.
Ready for your agents.

Supabase is an open-source backend as a service (BaaS) platform that provides developers with scalable and secure APIs and databases. Weld's Supabase connector is fully managed: it extracts data from Supabase, loads it into your warehouse, and keeps it in sync. The data lands in a clean, documented schema with agent context attached, so analysts can query it with SQL or dbt, and agents can query it over the Weld MCP server without guessing at tables or joins.

Weld MCP server

Ask your agent.
It can reach Supabase.

Connect Claude, Cursor, ChatGPT or your own agent to Weld over MCP. It finds the Supabase tables Weld has synced and queries your warehouse.
