# detect_silence

Analyzes a media file's audio for silent stretches using ffmpeg's silencedetect filter, run locally via child_process -- NOT via Premiere's scripting API, which has no audio-level/RMS reading capability at all (confirmed: every audio tool in this codebase only writes levels, never reads them). Requires ffmpeg on PATH; returns an explicit error if it is not found rather than failing silently. This is DETECTION ONLY -- it does not cut or modify anything. Use the returned intervals with split_clip/ripple_delete/razor_timeline_at_time if you want to remove the silence.

## Facts

- Tool: `detect_silence`
- Server: Adobe Premiere Pro (`adobe-premiere-pro-mcp`) — https://policylayer.com/tools/adobe-premiere-pro-mcp.md
- Install: `npx -y adobe-premiere-pro-mcp`
- Homepage: https://www.npmjs.com/package/adobe-premiere-pro-mcp
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 4
- Recommended policy verdict: Allowed

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `mediaPath` | string | no | Direct filesystem path to the media file to analyze |
| `projectItemId` | string | no | Project item ID to resolve to a media path instead of passing mediaPath directly |
| `noiseThresholdDb` | number | no | Silence threshold in dBFS, e.g. -30 (default -30). Audio quieter than this is considered silent. |
| `minDurationSeconds` | number | no | Minimum duration in seconds for a quiet stretch to be reported as silence (default 1.5) |

Parameters from the server's own tool schema.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "detect_silence",
    "arguments": {}
  }
}
```

## Why detect_silence is rated Low

Even though detect_silence only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Risk signals: Bulk/mass operation — affects multiple targets

## Use case

AI agents call detect_silence to retrieve information from Adobe Premiere Pro without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Adobe Premiere Pro:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "detect_silence": {}
  }
}
```
