AI agents use track_add_stereo 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.
This tool creates new data (a stereo audio track) within the project in a reversible manner. It does not execute arbitrary code, delete data, move financial resources, or trigger destructive operations. The action is standard audio project modification that can be undone.
From the tool's definition Tool name 'track_add_stereo' and description 'Add a new stereo audio track to the project' indicate creation of a new audio track within the Audacity project.
Documented attack patterns abuse exactly the kind of access track_add_stereo 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 track_add_stereo:
{
"version": "1",
"default": "deny",
"tools": {
"track_add_stereo": {
"limits": [
{
"counter": "track_add_stereo_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}track_add_stereo 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.
Free to start. No card required.
Add a new stereo audio track to the project. 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 track_add_stereo: 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.
track_add_stereo 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 track_add_stereo 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 track_add_stereo. 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.
track_add_stereo 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.
