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`.

Adds support for the new StreamableHttp transport. I'm not aware of any
clients that implement it, but somebody's gotta make the start! Once
some clients support it, we can also advertise it in the README.
Motivation: Keeping the readme up to date is a manual effort - this
keeps it automatically up to date and prevents things like
https://github.com/microsoft/playwright-mcp/pull/214 and other
consistency errors in the future.
This PR updates the binary name in `package.json` from `mcp` to
`mcp-server-playwright` as requested in issue #33. The change makes the
binary name more specific, avoiding conflicts with other MCP servers and
improving usability for global installations.
Fixes#33
