What Playwright MCP does well

•Turns any coding agent (Claude Code, Cursor, Windsurf) into a browser-capable assistant - navigate, click, screenshot, and assert from your IDE
•Zero additional cost - MCP is an open protocol and Playwright MCP is free and open source
•Great for ad-hoc debugging - ask your agent to open the app, click around, and confirm a fix works before you commit
•Flexible and composable - combine with other MCP servers for file access, database queries, and API calls in a single prompt
•Browser MCP support is appearing across coding agents, so developers can inspect apps from their IDE

Where Playwright MCP falls short

—MCP gives your agent a browser, but you still decide what to test, write assertions, and wire it into CI yourself
—No persistence between sessions - every test is a one-shot prompt. There’s no test suite, no history, no regression tracking
—No CI integration - MCP runs in your local IDE session. Getting it into GitHub Actions means building custom scripts, managing headless browsers, and handling auth tokens yourself
—No PR awareness - MCP doesn’t know what changed in your code. You manually decide what to test on every PR
—No recordings or evidence - MCP takes screenshots if you ask, but there’s no automatic video recording, step trace, or audit trail
—No maintained suite - when your UI changes, previous prompts can stop working with no coverage history or PR signal

How Zerocheck differs

Push a PR, get the approved suite plus suggestions - Zerocheck runs approved tests, reads the diff, saves suggested tests for review, and posts results with a recording
Persistent test suite with regression tracking - every PR builds on a maintained suite, not one-off prompts that vanish after the session
GitHub App workflow with no custom scripts, headless browser config, or auth token plumbing
Automatic recordings and step traces on every test run
JSON run evidence generated from executed browser runs
Visual interaction with confidence checks - when Zerocheck cannot act confidently, the run fails with evidence instead of silently passing

FAQ

Can Playwright MCP replace E2E testing?

Playwright MCP is useful for ad-hoc browser automation during development. It runs in your IDE session with no persistent suite, CI integration, regression tracking, or recordings. Every test is a one-shot prompt that vanishes when the session ends. Zerocheck provides a maintained approved suite that runs on PRs, with recordings and evidence for executed runs.

Should I use Playwright MCP or Zerocheck?

Use both for different purposes. Playwright MCP is useful for ad-hoc debugging, one-off browser automation, and verifying a fix during development. Zerocheck is built for approved E2E coverage on PRs, production monitoring, and JSON run evidence.

How do I get Playwright MCP tests into CI?

MCP runs inside your coding agent’s session, not in a CI pipeline. Getting MCP-style browser automation into GitHub Actions means writing custom scripts, managing headless browser infrastructure, handling authentication, and building reporting yourself. Zerocheck installs as a GitHub App and posts results directly in your PR.

Does Playwright MCP generate test recordings?

Playwright MCP can take screenshots when you ask, but it does not produce video recordings, step traces, or evidence artifacts automatically. Zerocheck records executed browser runs with video, screenshots, and step-by-step trace that you can review in the PR comment or dashboard.

Is Playwright MCP free compared to Zerocheck?

Playwright MCP is free and open source. However, it requires your time on every PR: deciding what to test, writing the prompt, reviewing the result, and handling CI integration yourself. Zerocheck is a paid service that automates all of this. The tradeoff is your time and coverage consistency versus a subscription.

What happens to my Playwright MCP tests when the UI changes?

Playwright MCP prompts reference specific UI elements and page structures. When your UI changes, previous prompts may not work correctly, and there is no notification that this has happened. There is no self-healing mechanism. Zerocheck uses visual interaction and confidence checks. Low-confidence interactions fail with evidence instead of silently passing.
