Analyze a WAV audio file to extract waveform amplitude data and detect peaks/transients. First call get-audio-info to retrieve the sourceFilePath, then pass it here. Returns normalized amplitude values (0-1) at evenly spaced time intervals plus an array of peak times where transients are detected.
AI agents call analyze-audio-waveform to retrieve information from After Effects MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs pure data retrieval and analysis of audio properties without side effects. It queries audio waveform characteristics and returns computed results (normalized amplitudes and peak detection) without creating, modifying, or deleting any assets or triggering external operations. This is characteristic of Read category tools.
From the tool's definition Tool description states it 'analyze[s]' and 'extract[s]' waveform data, 'retrieve[s]' sourceFilePath, and 'returns' amplitude values and peak times. No modification, deletion, execution of code, or financial operations are performed.
Documented attack patterns abuse exactly the kind of access analyze-audio-waveform gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and After Effects MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for analyze-audio-waveform:
{
"version": "1",
"default": "deny",
"tools": {
"analyze-audio-waveform": {}
}
}analyze-audio-waveform is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Analyze a WAV audio file to extract waveform amplitude data and detect peaks/transients. First call get-audio-info to retrieve the sourceFilePath, then pass it here. Returns normalized amplitude values (0-1) at evenly spaced time intervals plus an array of peak times where transients are detected. It is categorised as a Read tool in the After Effects MCP Server MCP Server, which means it retrieves data without modifying state.
Register the After Effects MCP Server MCP server in PolicyLayer and add a rule for analyze-audio-waveform: 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 After Effects MCP Server. Nothing to install.
analyze-audio-waveform 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 analyze-audio-waveform 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 analyze-audio-waveform. 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.
analyze-audio-waveform is provided by the After Effects MCP Server MCP server (thellamainator/after-effects-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from After Effects MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
