set_layout_mode · Talk to Figma MCP: Risk & Policy

WHAT IT DOES

What set_layout_mode does on Talk to Figma MCP

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

WHY IT NEEDS A POLICY

Why set_layout_mode needs a policy

This tool modifies design properties (layout mode and wrap behavior) in Figma, which is a Write operation—it creates or modifies data reversibly without deleting or destroying anything. The change can be undone by setting different layout parameters. Severity is medium because misconfiguration of layout properties could disrupt a design's structure, but the effect is contained to a single frame and fully reversible.

From the tool's definition Tool name 'set_layout_mode' combined with description 'Set the layout mode and wrap behavior of a frame in Figma' indicates modification of frame properties. This is a reversible change to design metadata.

Verdict

set_layout_mode Rate-limited

set_layout_mode stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

How do I block set_layout_mode completely? +

Set action: deny in the PolicyLayer policy for set_layout_mode. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides set_layout_mode? +
