object_duplicate · SVG Canvas MCP: Risk & Policy

WHAT IT DOES

What object_duplicate does on SVG Canvas MCP

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

WHY IT NEEDS A POLICY

Why object_duplicate needs a policy

Duplicating an object is a reversible write operation that modifies the canvas state by adding new content. It does not execute external code, delete data irreversibly, or move money. The low severity reflects that the blast radius of accidental duplication in an SVG design tool is minimal—duplicates can be easily removed.

From the tool's definition The tool name 'object_duplicate' combined with the description 'duplicates an object' (translated from Korean: '객체를 복제합니다') indicates it creates a copy of an existing SVG object within the canvas.

What risk level is object_duplicate? +

object_duplicate is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit object_duplicate? +

Yes. Add a rate_limit block to the object_duplicate 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 object_duplicate completely? +
