WHAT IT DOES

What add_clip_effect does on Media-Editor-MCP

WHY IT NEEDS A POLICY

Why add_clip_effect needs a policy

The tool creates or modifies video editing elements (effects on clips) reversibly within a draft project. This is consistent with Write category—changes can be undone in the editor. Severity is medium because misuse could corrupt or deface a project, but effects are applied to individual clips and are not destructive or financial.

From the tool's definition Tool name 'add_clip_effect' indicates modification of video clip properties. Description is empty, limiting precision. Sibling tools like 'add_animation', 'add_filter', 'add_audio', 'add_text' all perform reversible modifications to media drafts.
