Overview

Apache Iceberg, both ways.
As a source or your warehouse.

Apache Iceberg is an open table format for large analytic datasets, letting multiple engines read and write the same tables on object storage. Weld works with Apache Iceberg in both directions: replicate its tables into another warehouse, or use Apache Iceberg 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 Apache Iceberg.

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