AI agents use linetype_load to create or update resources in AutoCAD MCP Pro — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AutoCAD MCP Pro environment.
Based on the tool name alone, 'linetype_load' likely loads or imports a linetype definition into the current AutoCAD drawing, which is a Write operation (modifying drawing state by adding a resource). Confidence is low due to the empty description — it could also be a Read/lookup operation. Severity is medium as misuse could corrupt drawing linetypes.
From the tool's definition Tool name 'linetype_load' suggests loading a linetype resource into the drawing environment. Description is empty and uninformative.
Documented attack patterns abuse exactly the kind of access linetype_load gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and AutoCAD MCP Pro, and nothing reaches the server without passing your rules. This is the rule we recommend for linetype_load:
{
"version": "1",
"default": "deny",
"tools": {
"linetype_load": {
"limits": [
{
"counter": "linetype_load_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}linetype_load 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.

linetype_load. It is categorised as a Write tool in the AutoCAD MCP Pro MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the AutoCAD MCP Pro MCP server in PolicyLayer and add a rule for linetype_load: 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 Pro. Nothing to install.
linetype_load 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 linetype_load 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 linetype_load. 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.
linetype_load is provided by the AutoCAD MCP Pro MCP server (u-c4n/autocad-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from AutoCAD MCP Pro, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
