Smoke tests that
run themselves.
VibeCheck MCP connects your AI coding agent to a real Playwright browser. Describe a flow in plain English — the agent clicks through your app by itself, validates the result, and every run is recorded: video, console, network, every step. Failures arrive as ready-made, shareable bug reports.
Free API key · Works on localhost & VPN staging · No Playwright code to write
How it works
Prompt → browser → recording.
Two minutes of setup. Then your agent tests anything you can reach — localhost included.
Add the MCP server
One command in Claude Code (or a JSON snippet for Cursor, Windsurf, VS Code). Grab a free vck_ API key from Settings → API Keys.
Describe the test
Plain English, no Playwright code: “Go to /checkout, add a product, verify the total updates — record it and send me the link.”
“Go to /checkout, apply SAVE20, verify the total drops 20%. Record it.”
Get the recording
The agent drives a visible Chromium on your machine, validates the flow, and replies with a shareable track — pass or fail.
Agent-driven QA
You describe the flow. The agent does the rest.
No test scripts, no selectors, no CI setup. Your coding agent already understands your app — VibeCheck MCP gives it a real Playwright browser and records everything it does. Run smoke tests after every change, before every deploy, or whenever a PM asks “is checkout still working?”
- Plain-English tasks — the agent translates them into real clicks
- Visible Chromium on your machine: localhost and VPN staging work
- Validates results and reports pass or fail, with proof
- Every run is a track: video, console, network, action timeline
- A failed run is already a bug report — share the link, or let AI Fix open the PR
› Go to staging.myapp.com/cart, apply coupon SAVE20 and check the total drops 20%. Record it and send me the link.

Frequently asked questions
Agent Recording lets AI coding agents like Claude Code, Cursor and Windsurf drive a real browser on your machine via the VibeCheck MCP server. You describe a flow in plain English; the agent performs it with Playwright while VibeCheck records the whole session — video, console logs, network requests and a labeled action timeline — and returns a shareable track link.
Your agent writes the code.
