Overview

HTTP File in your warehouse.
Ready for your agents.

HTTP File syncs CSV, JSON and other data files served from any HTTP or HTTPS URL. Weld's HTTP File connector is fully managed: it extracts data from HTTP File, 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 HTTP File.

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