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

```json
{
  "jsonrpc": "2.0",

## Why create_lipsync is rated High

This tool triggers an external AI video generation operation — it processes an existing video and audio to produce a new lip-synced video. This is an Execute action: it invokes an external computational service whose output depends on the inputs (video, audio/TTS). It is not purely a Write (no simple data record is created) and not Destructive or Financial.

From the tool's own definition: "Create a lip-sync video by synchronizing mouth movements with audio. Supports both text-to-speech (TTS) with various voice options or custom audio upload."

## Use case

AI agents invoke create_lipsync to trigger actions in MCP Kling. 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.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches MCP Kling:
