object_scale · SVG Canvas MCP: Risk & Policy

WHAT IT DOES

What object_scale does on SVG Canvas MCP

AI agents use object_scale 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_scale needs a policy

This tool modifies the scale/size of an existing SVG canvas object. It is a reversible write operation (the object can be rescaled again), with low blast radius as it only affects graphical elements within an SVG document.

From the tool's definition 객체 크기를 조절합니다 (Adjusts/scales object size) - modifies an existing SVG object's dimensions

Verdict

object_scale Rate-limited

object_scale 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches SVG Canvas MCP, so you can run agents against it safely.

FAQ

Questions about object_scale

What does the object_scale tool do? +

객체 크기를 조절합니다. It is categorised as a Write tool in the SVG Canvas MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on object_scale? +

Register the SVG Canvas MCP server in PolicyLayer and add a rule for object_scale: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches SVG Canvas MCP. Nothing to install.

What risk level is object_scale? +

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

Can I rate-limit object_scale? +

Yes. Add a rate_limit block to the object_scale 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_scale completely? +

Set action: deny in the PolicyLayer policy for object_scale. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides object_scale? +

object_scale is provided by the SVG Canvas MCP server (kim62210/svg-canvas-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
