Overview

AWS Lambda in your warehouse.
Ready for your agents.

Weld's AWS Lambda connector enables seamless data syncing by triggering serverless functions to move and transform data to your destination efficiently. Weld's AWS Lambda connector is fully managed: it extracts data from AWS Lambda, 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 AWS Lambda.

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