style_stroke · SVG Canvas MCP: Risk & Policy

WHAT IT DOES

What style_stroke does on SVG Canvas MCP

AI agents use style_stroke 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 style_stroke needs a policy

This tool creates or modifies SVG stroke style attributes (e.g., stroke color, width, dash pattern) on objects. Such changes are reversible—stroke properties can be updated again or removed. There is no data deletion, code execution, financial impact, or external operation triggering. The blast radius is minimal: misuse affects only the visual styling of SVG graphics within the canvas.

From the tool's definition Tool name 'style_stroke' and description indicate modification of SVG object stroke styling properties. The Korean description translates to 'Sets the line style of an object,' which is a non-destructive modification operation.

Verdict

style_stroke Rate-limited

style_stroke 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.
