About this demo
A dashboard gets clean, accurate descriptions. The upstream tables feeding it? Usually nothing—or something stale and inconsistent. Copying that context column by column is the work that never quite gets done. With the Atlan MCP, you don't copy anything. Set the right description once at the source, then let the agent traverse lineage, identify every connected upstream asset, and propagate it in a single pass. The agent shows its work before touching anything—confirming the source asset and surfacing exactly which upstream assets it intends to update, with your explicit approval before any write. You authorize the right description; it handles the lineage and the updates. The metadata stays consistent, the judgment stays yours. No more opening each asset, copying, pasting, and saving—repeated for every column. The same pattern scales to any asset that participates in lineage: tables, data products, and more. And it's not just descriptions—propagate tags, ownership, or glossary terms the same way.
