voice_chat · Voice-AGI MCP Server MCP: Risk & Policy

WHAT IT DOES

What voice_chat does on Voice-AGI MCP Server

AI agents invoke voice_chat to trigger actions in Voice-AGI 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 voice_chat needs a policy

The tool facilitates a stateful, multi-turn voice conversation that can trigger tool execution, memory management, and research operations. Since it can invoke other tools and external operations depending on conversational inputs, it falls under Execute.

From the tool's definition 'Stateful voice conversation with context retention' combined with server description stating it 'enables users to execute tools, manage memory, and conduct research through natural multi-turn dialogue'
