Describe a user flow in English. Playwright MCP runs it as a real browser test, no test code required.
Add Playwright MCP to Claude Desktop — browsers are set up automatically.
Claude confirms Playwright is installed and a Chromium binary is available.
Test our signup flow: go to https://myapp.com/register, fill in the form with test@example.com, click submit, and verify we see a confirmation message.
Claude narrates each action as it runs and reports pass/fail at each step.
If anything fails, dump the DOM around the failure and the network request that broke.
DOM snippet + the failing request/response. Claude proposes a likely cause.
Take screenshots of each step and create a test report.
A folder of PNGs and a Markdown report you can paste into a PR description or QA log.
Automated browser testing without writing a single line of test code — best for one-off flow checks and regression sanity passes.
Most regressions are caught manually because writing a real test costs more than the bug itself. Playwright MCP makes the cost negligible: describe the flow once, run it whenever you want, save the result if you want to keep it.
This isn’t a replacement for a real test suite. It’s a replacement for “let me click around real quick to make sure that still works.”
