Why get_mass_properties needs a policy

This tool retrieves computed properties (mass, center of gravity, moments of inertia, etc.) from an already-loaded CAD model in SolidWorks. It performs no side effects, does not modify the model, does not execute arbitrary code, and does not delete or move data. It is a pure query operation, consistent with the Read category (search, list, get, fetch).

From the tool's definition Tool name 'get_mass_properties' and description 'Get mass properties of the current model' indicate a retrieval operation that queries existing model data without modification or execution of external processes.

POLICY

How to control get_mass_properties

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 get_mass_properties:

policy.json

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

get_mass_properties 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 get_mass_properties

What does the get_mass_properties tool do? +

Get mass properties of the current model. 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 get_mass_properties? +

Register the SolidWorks MCP Server MCP server in PolicyLayer and add a rule for get_mass_properties: 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 get_mass_properties? +

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

Can I rate-limit get_mass_properties? +

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

Set action: deny in the PolicyLayer policy for get_mass_properties. 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 get_mass_properties? +

get_mass_properties 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.
