WHAT IT DOES

What execute_python does on FreeCAD Robust MCP Server

AI agents invoke execute_python to trigger actions in FreeCAD Robust MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why execute_python is rated High

Executing arbitrary Python code is inherently an Execute action with critical severity. An AI agent could use this to run malicious scripts, modify files, exfiltrate data, or compromise the host system. The empty description reduces confidence slightly, but the tool name and server context (which explicitly mentions 'macro development' and 'debugging') make the intent clear.

From the tool's definition Tool name 'execute_python' indicates direct execution of Python code. Combined with server context (FreeCAD macro development and debugging), this tool permits arbitrary Python code execution within the FreeCAD environment.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs execute_python safely

PolicyLayer is an MCP gateway: it sits between your AI agents and FreeCAD Robust MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For execute_python, this is the rule to start with:

execute_python Rate-limited

execute_python 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.

View as policy code

policy.json

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

RATE-LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect FreeCAD Robust MCP Server, apply this rule, and every execute_python call is checked against it from then on.

FAQ

Questions about execute_python

What does the execute_python tool do? +

execute_python is a execute tool on the FreeCAD Robust MCP Server MCP server. It is categorised as a Execute tool in the FreeCAD Robust 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 execute_python? +

Register the FreeCAD Robust MCP Server MCP server in PolicyLayer and add a rule for execute_python: 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 FreeCAD Robust MCP Server. Nothing to install.

What risk level is execute_python? +

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

Can I rate-limit execute_python? +

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

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

execute_python is provided by the FreeCAD Robust MCP Server MCP server (spkane/freecad-addon-robust-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
