path_curveto · SVG Canvas MCP: Risk & Policy

WHAT IT DOES

What path_curveto does on SVG Canvas MCP

AI agents use path_curveto 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_curveto needs a policy

This tool creates or modifies SVG path elements by adding curve segments. It is reversible (paths can be edited or cleared) and produces only graphical output without side effects like code execution, data deletion, or financial impact. The action is additive and confined to the SVG canvas context, making it a Write-category tool with low severity due to limited blast radius if misused by an AI agent.

From the tool's definition Tool name 'path_curveto' and description 'adds a Bézier curve to the current path' indicates modification of SVG path data.

path_curveto Rate-limited

path_curveto 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.

FAQ

Questions about path_curveto

What does the path_curveto tool do? +

현재 패스에 베지어 곡선을 추가합니다. 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 path_curveto? +

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

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

Can I rate-limit path_curveto? +

Yes. Add a rate_limit block to the path_curveto 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 path_curveto completely? +

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

path_curveto 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.
