Add three new MCP tools for recording browser automation:
- browser_start_recording: Enable video recording with configurable size/filename
- browser_stop_recording: Stop recording and return video file paths
- browser_recording_status: Check recording status and configuration
Key features:
- Automatic video saving when pages/contexts close
- Configurable video size and output directory
- Enhanced LLM guidance with clear workflow instructions
- Integration with existing browser context management
Videos are saved as .webm files in {outputDir}/videos/ directory.

* HTTPS server launched and the relay server is created before MCP
server. This way we can pass CDP endpoint to its constructor.
* MCP HTTP transport is added to precreated HTTP server.
* A bunch of renames to fix style issues.
Instructions:
1. `git clone https://github.com/mxschmitt/playwright-mcp && git
checkout extension-drafft`
2. `npm ci && npm run build`
3. `chrome://extensions` in your normal Chrome, "load unpacked" and
select the extension folder.
4. `node cli.js --port=4242 --extension` - The URL it prints at the end
you can put into the extension popup.
5.
Put either this into Claude Desktop (it does not support SSE yet hence
wrapping it or just put the URL into Cursor/VSCode)
```json
{
"mcpServers": {
"playwright": {
"command": "bash",
"args": [
"-c",
"source $HOME/.nvm/nvm.sh && nvm use --silent 22 && npx supergateway --streamableHttp http://127.0.0.1:4242/mcp"
]
}
}
}
```
Things like `Take a snapshot of my browser.` should now work in your
Prompt Chat.
----
- SSE only for now, since we already have a http server with a port
there
- Upstream "page tests" can be executed over this CDP relay via
https://github.com/microsoft/playwright/pull/36286
- Limitations for now are everything what happens outside of the tab its
session is shared with -> `window.open` / `target=_blank`.
