# update_folder_slug

Source: https://modulify.ai/docs/mcp/folders/update-folder-slug

Changes the slug of one folder, the part of the dashboard URL that identifies it.

- Title: Change a folder web address
- Scope: `sites:write`
- Access: Makes changes

Any link someone saved to the old slug stops working immediately. A slug another folder in the workspace already holds is refused with `This folder URL already exists in this workspace!`, so check it with `check_folder_slug_available` first.

Unlike renaming, this does not need the **Edit folders** permission. See [Folders](https://modulify.ai/docs/projects/folders#rename-a-folder-or-change-its-url).
