export_multi_device · Rawtherapee MCP: Risk & Policy

WHAT IT DOES

What export_multi_device does on Rawtherapee

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

WHY IT NEEDS A POLICY

Why export_multi_device needs a policy

Export operations create or write new files, making this a Write action rather than Read. The 'multi_device' qualifier suggests batch output across multiple formats/destinations, which increases the blast radius (high severity) if an agent misuses export parameters—potentially overwriting files or creating unintended outputs.

From the tool's definition Tool name 'export_multi_device' on a photo development server (RawTherapee CLI) suggests writing/exporting processed images to multiple outputs. Context: sibling tools include adjustment and application functions typical of a photo editor.
