Create a rectangle in AutoCAD with optional color and thickness
AI agents use create_rectangle to create or update resources in AutoCAD MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AutoCAD MCP Server environment.
The tool creates new objects (rectangles) in AutoCAD, modifying the drawing state. This is clearly Write category behavior: it creates data that can be subsequently modified or deleted. While the sibling tools include destructive operations (delete_all_entities, delete_entities_by_color), this specific tool only adds geometry.
From the tool's definition Tool name is 'create_rectangle' and description states 'Create a rectangle in AutoCAD' — this creates new geometric entities in the drawing, which is a reversible modification of the design file.
Documented attack patterns abuse exactly the kind of access create_rectangle gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and AutoCAD MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_rectangle:
{
"version": "1",
"default": "deny",
"tools": {
"create_rectangle": {
"limits": [
{
"counter": "create_rectangle_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_rectangle 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.

Create a rectangle in AutoCAD with optional color and thickness. It is categorised as a Write tool in the AutoCAD MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the AutoCAD MCP Server MCP server in PolicyLayer and add a rule for create_rectangle: 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 AutoCAD MCP Server. Nothing to install.
create_rectangle 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 create_rectangle 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 create_rectangle. 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.
create_rectangle is provided by the AutoCAD MCP Server MCP server (thepiruthvirajan/autocad-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
