Find beats in the selected audio and add labels at beat positions.
AI agents use analyze_beat_finder to create or update resources in AudacityMCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AudacityMCP environment.
The tool analyzes audio (Read) but also writes beat labels to the project at detected positions, making it a Write operation. Labels are reversible modifications to the project. Severity is medium because an AI agent adding incorrect beat labels could disrupt project organization, but the action is reversible.
From the tool's definition add labels at beat positions
Documented attack patterns abuse exactly the kind of access analyze_beat_finder gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and AudacityMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for analyze_beat_finder:
{
"version": "1",
"default": "deny",
"tools": {
"analyze_beat_finder": {
"limits": [
{
"counter": "analyze_beat_finder_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}analyze_beat_finder stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Find beats in the selected audio and add labels at beat positions. It is categorised as a Write tool in the AudacityMCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Audacity MCP server in PolicyLayer and add a rule for analyze_beat_finder: 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 AudacityMCP. Nothing to install.
analyze_beat_finder is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the analyze_beat_finder 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 analyze_beat_finder. 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.
analyze_beat_finder is provided by the Audacity MCP server (xdarkzx/audacity-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
