Overview

MySQL, both ways.
As a source or your warehouse.

MySQL is an open-source relational database management system. Weld works with MySQL in both directions: replicate its tables into another warehouse, or use MySQL as the warehouse your other sources load into. Either way the data lands in a clean, documented schema that analysts can query with SQL or dbt, and agents can query over the Weld MCP server.

Weld MCP server

Ask your agent.
It can reach MySQL.

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