E2E test runner using Chrome Pool (browserless/chrome) with parallel execution
If you already use Mtw E2e Runner, the mtw e2e runner mcp server is the piece that lets your assistant work with it directly. E2E test runner using Chrome Pool (browserless/chrome) with parallel execution.
The AI-native E2E test runner that writes, runs, and debugs tests for you.
The server ships on npm as skills, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
Action — Fieldsgoto — valueclick — selector or textwait — selector, text, gone, or value (ms)screenshot — value (filename)select — selector, valueclear — selectorpress — valuescroll — selector or value (px)hover — selectorevaluate — valuenavigate — valueConfiguration is passed through the environment: CHROME_POOL_URL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
This sits in the browser automation group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Mtw E2e Runner's toolset — Action, goto, click and 11 more — is a fair guide to whether it matches your workflow. It is maintained by fastslack; worth a glance at recent repository activity before you build anything load-bearing on it.
