# list_changes

Read the change feed: every write in this workspace, with who made it and which fields changed. To catch up, page forward: pass the returned `next_cursor` back as `after`. To see what happened recently, pass `latest: true` for the newest changes first.

Send it to `https://api.tandemcrm.app/mcp` (streamable HTTP). Most people never write this by hand: their agent picks the tool from its description.
