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

```json

  "jsonrpc": "2.0",

## Why browser_stop_video is rated High

This tool executes a browser action (stopping video) whose effects depend on the current browser state and what video is playing. It is not a read operation (no data retrieval), not a write operation in the traditional sense (not creating/modifying persistent data), and not destructive (the action is reversible by playing video again).

From the tool's own definition: "Tool name 'browser_stop_video' indicates it performs an action that stops video playback in a browser context. The Playwright server description confirms this tool enables browser automation and interaction with web content."

## Use case

AI agents invoke browser_stop_video to trigger actions in Playwright MCP. 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)
