path_cancel · SVG Canvas MCP: Risk & Policy

WHAT IT DOES

What path_cancel does on SVG Canvas MCP

AI agents use path_cancel 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 path_cancel needs a policy

This tool cancels/discards the current path being built in an SVG canvas context. It modifies the state of the drawing session by discarding in-progress work, which is a reversible write/state-change operation. It doesn't delete persisted data, execute code, or have financial implications. Severity is low since it only affects an in-progress drawing operation.

Verdict

path_cancel Rate-limited

path_cancel 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.
