What dimension_aligned does on AutoCAD MCP Pro
AI agents use dimension_aligned 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.
Why dimension_aligned is rated Medium
The tool's primary function is to add a dimension annotation to a drawing—a reversible modification that can be deleted or edited later. While it affects the CAD document, it does not execute arbitrary code, delete data irreversibly, or trigger external financial operations.
From the tool's definition Tool creates a new dimension object ('Create an aligned dimension') in the CAD drawing, which modifies the drawing structure by adding a dimension entity.
Attacks that exploit this kind of access
The rule that runs dimension_aligned safely
PolicyLayer is an MCP gateway: it sits between your AI agents and AutoCAD MCP Pro, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For dimension_aligned, this is the rule to start with:
dimension_aligned 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.
The button opens the PolicyLayer dashboard: create your workspace, connect AutoCAD MCP Pro, apply this rule, and every dimension_aligned call is checked against it from then on.
Questions about dimension_aligned
Create an aligned dimension that measures the true distance between two points. 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 dimension_aligned: 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.
dimension_aligned 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 dimension_aligned 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 dimension_aligned. 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.
dimension_aligned 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.
