Why execute_python needs a policy

The tool allows execution of arbitrary Python code in the Metashape environment. Given the server's capabilities to manipulate photogrammetry workflows, generate 3D models, and export data, an AI agent with access to execute_python could: (1) modify project data, (2) exfiltrate sensitive mapping or model data, (3) trigger unintended drone operations or external tool invocations, (4) corrupt projects or exported…

From the tool's definition Tool name 'execute_python' with no description indicates arbitrary Python code execution within Metashape.

POLICY

How to control execute_python

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

policy.json

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

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.

Create a free account and register Metashape 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 execute_python

What does the execute_python tool do? +

execute_python. It is categorised as a Execute tool in the Metashape 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 Metashape 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 Metashape 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 Metashape MCP Server MCP server (jenkinsm13/metashape-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Metashape MCP Server tool call.

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