AI agents call voice_statistics to retrieve information from Voice Mode without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool queries and presents telemetry data about voice conversation performance metrics (response counts, success rates, turnaround times, provider usage). There is no indication that it modifies state, executes external operations, deletes data, or commits financial transactions.
From the tool's definition Tool name 'voice_statistics' and description 'Display live statistics dashboard' with 'Shows current session statistics' — this retrieves and displays existing performance metrics without modifying, executing operations, or side effects.
Documented attack patterns abuse exactly the kind of access voice_statistics gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Voice Mode, and nothing reaches the server without passing your rules. This is the rule we recommend for voice_statistics:
{
"version": "1",
"default": "deny",
"tools": {
"voice_statistics": {}
}
}voice_statistics is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Display live statistics dashboard for voice conversation performance. Shows current session statistics including: - Total responses and success rate - Average turnaround times (TTFA, TTS, STT) - Min/max performance metrics - Provider usage statistics - Recent interaction history Returns: Formatted text dashboard with real-time conversation statistics. It is categorised as a Read tool in the Voice Mode MCP Server, which means it retrieves data without modifying state.
Register the Voice Mode MCP server in PolicyLayer and add a rule for voice_statistics: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Voice Mode. Nothing to install.
voice_statistics is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the voice_statistics rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for voice_statistics. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
voice_statistics is provided by the Voice Mode MCP server (mbailey/voicemode). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Voice Mode, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
