# A component you build once updates every artifact that uses it

2026-09-30 | new | artifacts, agents | https://www.gatlas.ai/changelog/2026-09-30-reusable-components

Your agent saves a chart as a component and changes it in every artifact at once.

Over the Model Context Protocol (MCP), the way your agent connects to Gatlas, your agent can save a chart or a table as a component with `create_component` and place it in any artifact. It needs a Read/write connection. Change it once with `edit_component` and every artifact that places it updates; an edit that would break one is refused. Components, under Artifacts in the sidebar, shows each one and where it is used.
