WHAT IT DOES

What crm_media_upload does on 0nmcp

AI agents use crm_media_upload to create or update resources in 0nmcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your 0nmcp environment.

RISK

Why crm_media_upload is rated Medium

The tool creates or modifies data by uploading files to a CRM system's media library. It is reversible (files can typically be deleted), so it does not qualify as Destructive.

From the tool's definition Tool name contains 'upload' and description states 'Upload a file to the CRM media library.' This creates new data in the system that persists.
