How to control effect_high_pass_filter ↓

AI agents invoke effect_high_pass_filter to trigger actions in AudacityMCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

High Risk

The description is empty, so classification relies on name and server context. A high-pass filter is an audio effect that modifies audio data by attenuating frequencies below a cutoff point. In Audacity's context, applying an effect modifies the audio in the project, making it a Write/Execute operation.

From the tool's definition Tool name 'effect_high_pass_filter' and server context of audio editing/processing in Audacity

Documented attack patterns abuse exactly the kind of access effect_high_pass_filter 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 effect_high_pass_filter:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "effect_high_pass_filter": {
      "limits": [
        {
          "counter": "effect_high_pass_filter_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

effect_high_pass_filter stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

  1. Create a free account and register AudacityMCP — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

What does the effect_high_pass_filter tool do? +

effect_high_pass_filter. It is categorised as a Execute tool in the AudacityMCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on effect_high_pass_filter? +

Register the Audacity MCP server in PolicyLayer and add a rule for effect_high_pass_filter: 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.

What risk level is effect_high_pass_filter? +

effect_high_pass_filter is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit effect_high_pass_filter? +

Yes. Add a rate_limit block to the effect_high_pass_filter 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.

How do I block effect_high_pass_filter completely? +

Set action: deny in the PolicyLayer policy for effect_high_pass_filter. 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.

What MCP server provides effect_high_pass_filter? +

effect_high_pass_filter 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.

Enforce policy on every AudacityMCP tool call.
