Speak text using TTS
AI agents call voice_speak to retrieve information from Voice-AGI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs text-to-speech synthesis, which is an output/rendering operation. It reads text and produces audio output with no persistent side effects, no data modification, and no external system changes. Classified as Read (output generation) at low severity since misuse is limited to generating unwanted audio output.
From the tool's definition 'Speak text using TTS' — converts text to speech output; no data is created, modified, or deleted
