WHAT IT DOES

What tool_generate_speech does on Open Google Image Generator MCP

AI agents invoke tool_generate_speech to trigger actions in Open Google Image Generator MCP. 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 tool_generate_speech needs a policy

This tool triggers an external AI service (Gemini TTS) to synthesize audio and writes a WAV file to disk. It involves both an external API call and file system write, making Execute the most appropriate category. The blast radius is medium — it consumes cloud API credits and writes files to the local filesystem, but does not delete data or move money.

From the tool's definition Convert text to speech using Gemini TTS. Returns a WAV file path in outputs/.
