WHAT IT DOES

What analyze_script does on Metis Public Health

AI agents invoke analyze_script to trigger actions in Metis Public Health. 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 analyze_script needs a policy

The name 'analyze_script' most likely involves running or processing a script. Even if it only performs static analysis, the word 'script' combined with 'analyze' in an MCP context raises the possibility of code execution. The empty description lowers confidence, but the most severe plausible interpretation is Execute. Severity is high given potential for arbitrary code execution if misused.

From the tool's definition Tool name 'analyze_script' suggests execution or analysis of a script; description is empty and uninformative.
