WHAT IT DOES

What upload_media_file does on GoHighLevel MCP Server

AI agents use upload_media_file to create or update resources in GoHighLevel MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your GoHighLevel MCP Server environment.

WHY IT NEEDS A POLICY

Why upload_media_file needs a policy

The tool creates new media files in a library but does not execute arbitrary code, delete data irreversibly, or move funds. File uploads are standard write operations that can be undone by deletion. The 25MB size limit provides a practical constraint and poses minimal blast radius for typical media content storage.

From the tool's definition Tool explicitly performs an upload action which creates or adds new data: 'Upload a file to the media library or add a hosted file URL'. This is a reversible create operation on the media library storage.
