path_close · SVG Canvas MCP: Risk & Policy

WHAT IT DOES

What path_close does on SVG Canvas MCP

AI agents use path_close 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_close needs a policy

This tool creates or modifies SVG path data in a reversible manner. It does not execute arbitrary code, delete data irreversibly, or perform financial operations. It fits the Write category as it modifies the canvas state. Severity is low because closing a path has minimal blast radius - it only affects the current path geometry and can be easily undone by opening the path again or using undo operations.

From the tool's definition Tool name 'path_close' and description indicate it modifies an open path by closing it (connecting to start point). This is a reversible operation on SVG path data - the path can be reopened or modified.

Verdict

path_close Rate-limited

path_close 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.
