resize_node · MCP Figma MCP: Risk & Policy

WHAT IT DOES

What resize_node does on MCP Figma

AI agents use resize_node 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 resize_node needs a policy

Resizing a node modifies design properties but is fully reversible—the original size can be restored. This is a Write operation (modifies data reversibly) rather than Execute (which would be for running arbitrary commands). Severity is medium because misuse could corrupt design work or waste time, but changes are easily undone and don't affect data outside Figma or cause permanent loss.

From the tool's definition Tool name 'resize_node' and description 'Resize a node in Figma' indicate modification of design element properties.

Verdict

resize_node Rate-limited

resize_node 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.
