gemini_analyze · Gemini Cli MCP: Risk & Policy

WHAT IT DOES

What gemini_analyze does on Gemini Cli

AI agents invoke gemini_analyze to trigger actions in Gemini Cli. 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 gemini_analyze needs a policy

This tool sends files or code to an external AI service (Gemini) for analysis, triggering an external operation whose effects depend on the content of the arguments. It reads local files/code and transmits them to a third-party service, which constitutes executing an external operation rather than a simple local read.
