AI agents use draw_text 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.
This tool creates a new text object in an AutoCAD drawing. It is a Write operation as it adds/modifies drawing content reversibly (text can be deleted or edited afterward). No code execution, financial transaction, or irreversible destruction is involved. Severity is medium because misuse could corrupt or clutter technical drawings, but effects are reversible.
From the tool's definition 绘制单行文字 (Draw single-line text) — creates a new text entity in the AutoCAD drawing at specified coordinates with defined properties
Documented attack patterns abuse exactly the kind of access draw_text 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 draw_text:
{
"version": "1",
"default": "deny",
"tools": {
"draw_text": {
"limits": [
{
"counter": "draw_text_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}draw_text 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.

Register the AutoCAD MCP Server MCP server in PolicyLayer and add a rule for draw_text: 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.
draw_text 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_text 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_text. 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_text is provided by the AutoCAD MCP Server MCP server (zh19980811/easy-mcp-autocad). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
