WHAT IT DOES

What create_frame does on Claude Talk to Figma MCP

WHY IT NEEDS A POLICY

Why create_frame needs a policy

This tool creates design content (frames) in Figma without permanently destroying data or executing arbitrary code. Frames are standard Figma objects that can be edited, moved, or deleted by users. The action is reversible and has no destructive, financial, or code-execution implications. It is therefore Write-category (creates/modifies data reversibly).

From the tool's definition create_frame—creates a new frame in Figma. The tool name and description explicitly indicate it generates new design elements that can be modified or deleted reversibly.
