Overview

FTP in your warehouse.
Ready for your agents.

FTP Server (File Transfer Protocol Server) is a standardized tool for transferring and storing files, such as CSVs and other formats, across networks. Weld's FTP connector is fully managed: it extracts data from FTP, 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 FTP.

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