What asc_upload_app_event_screenshot does on Appstoreconnect Mcp
AI agents use asc_upload_app_event_screenshot to create or update resources in Appstoreconnect Mcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Appstoreconnect Mcp environment.
Why asc_upload_app_event_screenshot is rated Medium
