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).

What detect_silence does on Adobe Premiere Pro
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.
| Parameter | Type | Required | Description |
|---|---|---|---|
mediaPath | string | — | Direct filesystem path to the media file to analyze |
projectItemId | string | — | Project item ID to resolve to a media path instead of passing mediaPath directly |
noiseThresholdDb | number | — | Silence threshold in dBFS, e.g. -30 (default -30). Audio quieter than this is considered silent. |
minDurationSeconds | number | — | Minimum duration in seconds for a quiet stretch to be reported as silence (default 1.5) |
Parameters from the server's own tool schema.
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.

The rule that runs detect_silence safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Adobe Premiere Pro, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For detect_silence, this is the rule to start with:
detect_silence is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Adobe Premiere Pro, apply this rule, and every detect_silence call is checked against it from then on.
Questions about 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. It is categorised as a Read tool in the Adobe Premiere Pro MCP Server, which means it retrieves data without modifying state.
detect_silence accepts 4 parameters: mediaPath, projectItemId, noiseThresholdDb, minDurationSeconds. The full parameter table on this page comes from the server's own tool schema.
Register the Adobe Premiere Pro MCP server in PolicyLayer and add a rule for detect_silence: 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 Adobe Premiere Pro. Nothing to install.
detect_silence is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the detect_silence 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 detect_silence. 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.
detect_silence is provided by the Adobe Premiere Pro MCP server (adobe-premiere-pro-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
