Overview

SFTP in your warehouse.
Ready for your agents.

SFTP (Secure File Transfer Protocol) is a protocol used for transferring files over a network and provides file access, transfer, and management. Weld's SFTP connector is fully managed: it extracts data from SFTP, 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 SFTP.

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