object_order · SVG Canvas MCP: Risk & Policy

WHAT IT DOES

What object_order does on SVG Canvas MCP

AI agents use object_order 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_order needs a policy

This tool modifies the stacking order (z-index/layering) of SVG objects, which is a reversible data modification operation. It does not execute arbitrary code, delete data irreversibly, or move money. The change can be undone by reordering again. This is a typical Write category operation on graphical elements within the SVG canvas context.

From the tool's definition Tool name 'object_order' and description '객체의 Z 순서를 변경합니다' (changes the Z order of objects) indicates modification of object layering properties in SVG graphics.

Verdict

object_order Rate-limited

object_order 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_order

What does the object_order tool do? +

객체의 Z 순서를 변경합니다. 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_order? +

Register the SVG Canvas MCP server in PolicyLayer and add a rule for object_order: 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_order? +

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

Can I rate-limit object_order? +

Yes. Add a rate_limit block to the object_order 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_order completely? +

Set action: deny in the PolicyLayer policy for object_order. 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_order? +

object_order 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.
