run_avizo_python · Avizo MCP Server MCP: Risk & Policy

WHAT IT DOES

What run_avizo_python does on Avizo MCP Server

AI agents invoke run_avizo_python to trigger actions in Avizo 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.

WHY IT NEEDS A POLICY

Why run_avizo_python needs a policy

This tool directly executes Python scripts, which is a classic Execute category action. Python execution is unrestricted in scope — an AI agent could use this to perform any computation, access files, make network calls, or trigger side effects depending on script content. The high severity reflects the broad capabilities of Python execution and potential for unintended operations.

From the tool's definition Tool name 'run_avizo_python' and description 'Run a Python script using Avizo's bundled Python interpreter' — executes arbitrary Python code via Avizo's interpreter.
