Why measure_distance needs a policy

This tool reads/queries geometric data from the SolidWorks model by measuring the distance between two entities. It has no side effects, does not modify any data, and is purely a read/query operation.

POLICY

How to control measure_distance

PolicyLayer is an MCP gateway — it sits between your AI agents and SolidWorks MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for measure_distance:

policy.json

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

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 SolidWorks MCP Server — 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 measure_distance

What does the measure_distance tool do? +

Measure distance between two selected entities. It is categorised as a Read tool in the SolidWorks MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on measure_distance? +

Register the SolidWorks MCP Server MCP server in PolicyLayer and add a rule for 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 SolidWorks MCP Server. Nothing to install.

What risk level is measure_distance? +

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

Can I rate-limit measure_distance? +

Yes. Add a rate_limit block to the 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 measure_distance completely? +

Set action: deny in the PolicyLayer policy for 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 measure_distance? +

measure_distance is provided by the SolidWorks MCP Server MCP server (jianzhichun/solidworks-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every SolidWorks MCP Server tool call.

Start from SolidWorks MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
