Perplexity

Full content control in Claude Desktop

Stop jumping between your browser and the editor to tweak site copy. You can now use `create_object` or `update_object` to push changes to your bucket without leaving your chat window. It handles your media library too. Just trigger `create_media` or `delete_media` to keep your assets synced while you talk through your project needs.

Query objects and revisions

Need to see what changed in your content model? Use `list_revisions` or `get_revision` to see the history of any specific record. This MCP server gives you a direct line to your data. You can call `list_objects` with custom queries to pull exactly what you need for your current task.

Manage your schema definitions

Building a new content structure is faster when you define it via chat. Use `create_object_type` to set up new schemas on the fly. If your requirements shift, you can modify existing types with `update_object_type`. It keeps your CMS layout in sync with your evolving code.
