Playwright MCP Server
by Microsoft
Microsoft's Playwright MCP server gives an agent a controllable browser using accessibility-tree snapshots rather than screenshots, so it can reliably navigate pages, fill forms, click elements, and verify results. Handy for end-to-end testing, scraping structured data, and reproducing browser bugs.
Works with
The Model Context Protocol (MCP).
When to use it
- Writing or debugging end-to-end tests with agent help
- Extracting data from pages that need interaction
- Verifying a UI change actually works, not just compiles
When not to
- High-volume scraping of sites whose terms forbid it
What it does
- Navigate pages and interact with elements deterministically
- Fill and submit forms; extract structured content
- Reproduce and verify end-to-end flows
How to install

npx
Requires: Node.js
Add to your MCP config
The server manages its own browser via Playwright.

Playwright downloads a Chromium build on first use; allow it or point to an existing install.

How to prompt it
Copy-paste prompts written to exercise this plugin, with what to expect.
Verify a signup flow
You changed the signup form and want to confirm it still works.
Open http://localhost:3000/signup, fill the form with a test email and password, submit, and tell me what page you land on and any validation errors.
What to expect: The agent drives the browser through the flow and reports the resulting URL and any errors, so you know the change works before shipping.
- Ask it to snapshot the accessibility tree if an element isn't being found.
Tips for getting the most out of it
- It uses accessibility snapshots, so semantic, labeled UI is easier for the agent to drive — a nudge toward accessible markup.
- Run against a local dev server to keep test data contained.

Frequently asked questions
Screenshots or DOM?+
It primarily uses the accessibility tree, which is faster and more reliable than vision-based screenshot clicking, though it can capture images too.
