Overview

CircleCI in your warehouse.
Ready for your agents.

CircleCI is a continuous integration and delivery (CI/CD) platform that automates software testing, building, and deployment, helping development teams release code faster and more reliably. Weld's CircleCI connector is fully managed: it extracts data from CircleCI, 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 CircleCI.

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