Analyze audio output for a duration to detect sound vs silence and frequencies (see browser_docs)
AI agents call browser_get_audio_analysis to retrieve information from Browser MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and analyzes audio data from the browser without side effects. It does not execute code, modify page state, delete data, or cause external operations. Audio analysis is a passive inspection mechanism, making it a Read operation with low severity as misuse would only reveal information about audio output, posing minimal risk.
From the tool's definition Tool performs audio analysis to detect sound vs silence and frequencies. The action is observational and non-modifying—it analyzes existing audio output without creating, modifying, deleting, or executing code.
Attacks that exploit this kind of access
Analyze audio output for a duration to detect sound vs silence and frequencies (see browser_docs). It is categorised as a Read tool in the Browser MCP Server MCP Server, which means it retrieves data without modifying state.

browser_get_audio_analysis 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 browser_get_audio_analysis 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 browser_get_audio_analysis. 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.
