MOST DANGEROUS TOOLS

Critical Risk
Destructive · High track_remove This tool irreversibly deletes audio tracks, which cannot be undone by the tool itself (undo would be a separate operation in Audacity). Destructive · High edit_trim This tool irreversibly deletes all audio content outside the selected region. Destructive · High edit_delete This tool permanently removes audio content without saving it to the clipboard, making the deletion irreversible within the current editing context. Destructive · High edit_split_delete The tool permanently deletes selected audio content.

116 of AudacityMCP's 131 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

HOW TO CONTROL AUDACITYMCP

PolicyLayer is an MCP gateway — it sits between your AI agents and AudacityMCP, and nothing reaches the server without passing your rules. These are the rules we recommend:

Deny destructive operations
{
  "track_remove": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Blocked by default. Requires approval."
      }
    ]
  }
}

Destructive tools should never be available to autonomous agents without human approval.

Rate limit write operations
{
  "project_new": {
    "limits": [
      {
        "counter": "project_new_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations
{
  "analyze_contrast": {
    "limits": [
      {
        "counter": "analyze_contrast_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

  1. Create a free account and register AudacityMCP — nothing to install.
  2. Add these rules — paste them, or build them visually. Tune the limits to your setup.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Can an AI agent delete data through the Audacity MCP server? +

Yes. The AudacityMCP server exposes 4 destructive tools including track_remove, edit_delete, edit_split_delete. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.

How do I prevent bulk modifications through AudacityMCP? +

The AudacityMCP server has 72 write tools including project_new, track_mix_and_render_to_new, analyze_beat_finder. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach AudacityMCP.

How many tools does the Audacity MCP server expose? +

131 tools across 4 categories: Destructive, Execute, Read, Write. 15 are read-only. 116 can modify, create, or delete data.

How do I enforce a policy on AudacityMCP? +

Register the Audacity MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every AudacityMCP tool call.

Deterministic rules across all 131 AudacityMCP tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
