AI agents use draw_rectangles to create or update resources in 🪄 ImageSorcery MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your 🪄 ImageSorcery MCP environment.
Drawing rectangles onto an image is a write/modification operation — it creates or alters visual content. Sibling tools (draw_arrows, draw_circles, draw_lines, draw_texts) all follow the same pattern of annotating/modifying images, which is reversible in principle (original can be retained). Empty description lowers confidence.
From the tool's definition Tool name 'draw_rectangles' implies drawing/adding rectangle shapes to an image, which modifies image data. Description is empty, so classification is based on name alone.
Documented attack patterns abuse exactly the kind of access draw_rectangles gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and 🪄 ImageSorcery MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for draw_rectangles:
{
"version": "1",
"default": "deny",
"tools": {
"draw_rectangles": {
"limits": [
{
"counter": "draw_rectangles_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}draw_rectangles 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.

draw_rectangles. It is categorised as a Write tool in the 🪄 ImageSorcery MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the 🪄 ImageSorcery MCP server in PolicyLayer and add a rule for draw_rectangles: 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 🪄 ImageSorcery MCP. Nothing to install.
draw_rectangles is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the draw_rectangles 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.
Set action: deny in the PolicyLayer policy for draw_rectangles. 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.
draw_rectangles is provided by the 🪄 ImageSorcery MCP server (sunriseapps/imagesorcery-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
