draw_path · SVG Canvas MCP: Risk & Policy

WHAT IT DOES

What draw_path does on SVG Canvas MCP

AI agents use draw_path 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 draw_path needs a policy

The tool creates new SVG path elements or modifies existing paths within the canvas. This is a reversible write operation—paths can be edited or deleted without permanent data loss. It does not execute code, delete data irreversibly, or trigger external operations. While it manipulates the SVG document, the changes are confined to graphic design operations and can be undone or overwritten.

From the tool's definition Tool name is 'draw_path' and description indicates it 'draws paths directly with SVG path data (d attribute)'. This creates or modifies SVG graphic content.

Verdict

draw_path Rate-limited

draw_path 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.
