Why analysis_measure_distance needs a policy

This tool performs a pure geometric calculation, computing the distance between two points. It reads/computes data with no side effects, no data modification, and no external operations triggered.

POLICY

How to control analysis_measure_distance

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 analysis_measure_distance:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "analysis_measure_distance": {}
  }
}

analysis_measure_distance is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register AutoCAD MCP Pro — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about analysis_measure_distance

What does the analysis_measure_distance tool do? +

Measure the Euclidean distance between two points. It is categorised as a Read tool in the AutoCAD MCP Pro MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on analysis_measure_distance? +

Register the AutoCAD MCP Pro MCP server in PolicyLayer and add a rule for analysis_measure_distance: 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.

What risk level is analysis_measure_distance? +

analysis_measure_distance is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit analysis_measure_distance? +

Yes. Add a rate_limit block to the analysis_measure_distance 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.

How do I block analysis_measure_distance completely? +

Set action: deny in the PolicyLayer policy for analysis_measure_distance. 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.

What MCP server provides analysis_measure_distance? +

analysis_measure_distance 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.

Enforce policy on every AutoCAD MCP Pro tool call.

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.
