How to Use the Cosmic MCP in Claude

Q: Can I safely delete CMS objects using Cosmic inside Claude Desktop?

Yes, but use caution. Your agent can run wipecmsobject to drop live document rows, which wipes them out permanently. Always verify the target ID in your chat before letting the tool run.

Q: How does Claude Desktop handle media asset cleanup with Cosmic?

The agent runs wipemediaasset to trigger disk removals on your storage bucket. It checks the asset ID first to make sure you aren't deleting a file that is currently active.

Perplexity

Mutate Cosmic CMS content directly from Claude Desktop.

Your agent runs `patch_cms_object` to swap out values on the fly, or spins up fresh drafts using `create_cms_object` right inside your chat box. This MCP Server hooks directly into your local Claude Desktop config file. You write back to your production CMS without leaving your workspace.

Inspect and pull media assets in Claude Desktop.

Your agent runs `get_media_asset` and `list_uploaded_media` to locate assets and check their properties in real time. Claude Desktop uses these tools to inspect your media library arrays. You get the exact file metadata you need to drop straight into your code or content updates.

Audit schema rules and bucket structures.

Your agent pulls the exact rules driving your fields using `get_schema_details` and `list_schema_types`. It uses `list_bucket_objects` to map out your headless routing spaces. You can debug schema mismatches in Claude Desktop before you push any broken payloads.
