Why macro_start_recording needs a policy

This tool allows starting macro recording in SolidWorks, which captures and enables execution of scripted operations. While macro recording itself is reversible, it enables the creation of code that can perform Execute-category actions (running scripts, triggering external operations). The tool directly facilitates executable automation and falls into the Execute category.

From the tool's definition The tool 'macro_start_recording' initiates recording of a macro in SolidWorks. Macros are executable scripts that can automate arbitrary operations within the CAD application, including model modifications, file operations, and external actions.

POLICY

How to control macro_start_recording

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 macro_start_recording:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "macro_start_recording": {
      "limits": [
        {
          "counter": "macro_start_recording_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

macro_start_recording stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. 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 macro_start_recording

What does the macro_start_recording tool do? +

Start recording a new macro. It is categorised as a Execute tool in the SolidWorks MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on macro_start_recording? +

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

macro_start_recording is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit macro_start_recording? +

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

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

macro_start_recording 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.
