AI agents call point_from_snap to retrieve information from AutoCAD MCP Pro without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Based on the name alone, 'point_from_snap' likely reads/queries a snap point coordinate from the CAD drawing, which is a read operation. However, the empty description lowers confidence. In AutoCAD contexts, snapping typically retrieves geometry data without side effects. Severity is low as misuse would at most return incorrect coordinates.
From the tool's definition Tool name 'point_from_snap' suggests snapping to a point in the CAD environment; description is empty and uninformative.
Documented attack patterns abuse exactly the kind of access point_from_snap 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 point_from_snap:
{
"version": "1",
"default": "deny",
"tools": {
"point_from_snap": {}
}
}point_from_snap is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

point_from_snap. It is categorised as a Read tool in the AutoCAD MCP Pro MCP Server, which means it retrieves data without modifying state.
Register the AutoCAD MCP Pro MCP server in PolicyLayer and add a rule for point_from_snap: 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.
point_from_snap is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the point_from_snap 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 point_from_snap. 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.
point_from_snap 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.
