design_iteration · Illustrator MCP Server MCP: Risk & Policy

WHAT IT DOES

What design_iteration does on Illustrator MCP Server

AI agents invoke design_iteration to trigger actions in Illustrator MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why design_iteration needs a policy

This tool executes design operations in Adobe Illustrator through ExtendScript execution. While the operations are reversible (design changes can be undone), the tool's ability to automatically fix issues and execute arbitrary design transformations qualifies it as Execute rather than Write. The blast radius is high because an AI agent could inadvertently modify complex design documents in unintended ways.

From the tool's definition The tool description states it 'Run[s] a complete design iteration' with options to 'auto-fix issues', which involves executing design operations within Adobe Illustrator.

What risk level is design_iteration? +

design_iteration is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit design_iteration? +

Yes. Add a rate_limit block to the design_iteration rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block design_iteration completely? +
