WHAT IT DOES

What execute_script_headless does on Blender Copilot MCP Server

AI agents invoke execute_script_headless to trigger actions in Blender Copilot 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_script_headless is rated High

This tool executes code with full Blender API access in headless mode. Without restrictive descriptions or whitelisting, an AI agent could execute arbitrary Python/Blender scripts affecting file systems, network calls, or rendering pipelines. Headless mode amplifies risk by enabling batch operations on multiple files or scenes.

From the tool's definition Tool name 'execute_script_headless' indicates execution of arbitrary scripts in a Blender headless (non-interactive) environment.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs execute_script_headless safely

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

execute_script_headless Rate-limited

execute_script_headless 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.

    }
  }
}

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

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