execute_blender_code

THE RISK

High Risk

This tool falls under Execute because it runs code whose effects depend entirely on the arguments (the Python code provided). The ability to execute arbitrary code in Blender represents a critical severity risk because an AI agent could inadvertently or maliciously: modify files on disk, access the filesystem, exfiltrate data, corrupt the Blender project, install packages, or perform any operation that Blender's…

From the tool's definition Tool description states "Execute arbitrary Python code in Blender" with a parameter allowing any Python code to be passed.

HOW TO CONTROL EXECUTE_BLENDER_CODE

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

policy.json

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

execute_blender_code 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 Tripo 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

What does the execute_blender_code tool do? +

Execute arbitrary Python code in Blender. Parameters: - code: The Python code to execute. It is categorised as a Execute tool in the Tripo 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_blender_code? +

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

What risk level is execute_blender_code? +

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

Can I rate-limit execute_blender_code? +

Yes. Add a rate_limit block to the execute_blender_code 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_blender_code completely? +

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

execute_blender_code is provided by the Tripo MCP Server MCP server (vast-ai-research/tripo-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Tripo MCP Server tool call.
