WHAT IT DOES

What set_padding does on MCP Figma

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

WHY IT NEEDS A POLICY

Why set_padding needs a policy

This tool creates or modifies design data (padding values) within Figma frames, which is reversible and does not delete content or execute arbitrary code. It falls under Write category. Severity is medium because padding changes affect design layouts and could disrupt user work, but changes are easily undone via undo/redo in Figma.

From the tool's definition Tool description states 'Set padding values for an auto-layout frame in Figma' — directly modifies frame properties.
