  This is so good. I've been using it with Claude Code with great success.I just leave an instruction in CLAUDE.md to validate changes with Playwright. It automatically starts a dev server (wrote a little MCP server to do that), navigates to the page with the changes it just made, and validates that its changes worked. If there is anything unexpected, it self-corrects.It's like working with a really great mid-level engineer.What a time to be alive.

  It uses ariaSnapshot, which is an accessible representation of the DOM used by screen readers and accessibility validation tools as well as playwright testing.However, even with that, it will quickly exhaust the model context if you navigate to something like Gmail. I just verified this with cursor.I've been playing around with a much better textual representation of the page that's much more compact:https://github.com/lxe/chrome-mcp/blob/master/src/runtime-te...This uses your own chrome session and doesn't require a huge context size.I might refactor this to use the aria interface available to the CDP, which I wasn't aware of at the time.

  I’m going to see if I can use this in combination with our JIRA MCP to read a bug ticket’s “steps to reproduce” to see if it translate those steps to actually reproduce those actions.I don’t understand the hate against MCP. It is truly exciting to see the Cambrian explosion of “connectors” coming out.This is going to be the “App Store” for models in a way that OpenAI’s custom GPTs never was.

  It seems this new tool from Microsoft is a competitor to https://github.com/executeautomation/mcp-playwrightThe Microsoft one seems simpler, whereas the other one has more tools.

  Submitted acouple times, would love to hear more.Note also, there's a Fetch-MCP which is playwright based, supports batch. Would be interesting to compare. https://github.com/jae-jae/fetch-mcp https://news.ycombinator.com/item?id=43419713 (64 points, 6 days ago, 14 comments)

  I want an MCP for capybara so LLMs can write my Rails system tests and debug them when they don't work.

  I don't know playwright, but how is this different than puppeteer?The issue I'm noticing with puppeteer is that it isn't always successful to immediately get the right javascript to complete a simple task such as accepting a cookie consent banner, for example.

  Great release! But i'm wondering why they didn't just support the original Playwright APIs instead of the subset of actions.

  "code --add-mcp"Vscode comes with a built in MCP client ?

  Is this for test automation? or for using Playwright as "Operator" in an Agent?

  Interestingly it transforms the page into markdown for navigation.
