Playwright MCP uses a session and prevents proper cache clearing. How many times did Claude tell me "Perfect Deployment!" only to open the console and see a row of errors? It's all about control and caching. Claude does just fine writing its own Playwright scripts. I can't see any use for the MCP at this point. Tell me if I'm wrong.
I have successfully integrated this playwright mcp -Microsoft one ( adding tools ) to Claude code . We can now add a prompt and pass it in Claude code headless cli .. however the browser navigation is quite slow .. for example it takes more than 4 seconds for Claude code to login using username and password..
How did you speed up the process ..? I am using WSL2
Thanks in advance

I’ve been messing around with the new Playwright MCP inside Claude Code and it’s honestly wild.
It doesn’t just simulate tests or spit out scripts — it actually opens a live Chromium browser that you can watch while it runs your flow.
I set it up to test my full onboarding process:
signup → verification → dashboard → first action.
Claude runs the flow step by step, clicks through everything, fills the forms, waits for network calls, takes screenshots if something breaks. You literally see the browser moving like an invisible QA engineer.
No config, no npm, no local setup. You just say what you want to test and it does it.
You can even ask it to export the script if you want to run the same test locally later, but honestly the built-in one is enough for quick checks.
Watching it run was kind of surreal — it caught two console errors and one broken redirect that I hadn’t noticed before.
This combo basically turns Claude Code into a test runner with eyes.
If you’re building web stuff, try enabling the Playwright MCP in Claude Code.
It’s the first time I’ve seen an AI actually use a browser in front of me and do proper end-to-end testing.
Just saw a YT video about using playwright mcp. All the behaviors described (screenshots, etc) are available to CC without installing or using MCP, so I’m just curious, is there value to using the MCP over simply asking Claude to “use playwright to visit blah and screenshot the results, review the error and fix”
Hey folks,
Following up on my earlier post I’ve been documenting everything I learned about Claude Code — massive thanks to everyone who shared feedback and ideas. It’s been super helpful.
Just pushed a round of new updates focused on making MCP server setup seamless:
Step-by-step installation guides for popular servers — Playwright, Memory, Sequential Thinking, and more
A consolidated troubleshooting guide for common issues across all MCP integrations
Short, focused use-case breakdowns
The goal here was to make getting started with MCP servers as frictionless as possible — from install to real usage. Each guide includes working config examples and fixes for the most common setup pitfalls.
📘 Repo: Claude Code — Everything You Need to Know
If you’re looking to extend Claude Code with MCP servers, these additions should help you make better decisions while saving tokens and cost.
Feedback and contributions always welcome.
I’ve been using a few MCPs in my setup lately, mainly Context 7, Supabase, and Playwright.
I'm just curious in knowing what others here are finding useful. Which MCPs have actually become part of your daily workflow with Claude Code? I don’t want to miss out on any good ones others are using.
Also, is there anything that you feel is still missing as in an MCP you wish existed for a repetitive or annoying task?
No matter what I try, Claude code cannot access the Microsoft Playwright MCP. I'm searching for troubleshooting tips, but can't find anything. Is there anyone using it?
[EDIT] Solved, "claude mcp add playwright -- npx "@playwright/mcp@latest" worked.

It seems that using Playwright or Puppeteer MCPs actually gives Claude Code “eyes” and “hands,” making it much easier to close the loop of coding → testing → validating → refactoring. However, the token consumption is massive, and after just one or two tests, the chat gets compacted. I tried delegating this to a subagent, but the results weren’t great. Do you have any tips for handling this? I’m also considering testing the browser-use MCP (https://github.com/browser-use/browser-use) - maybe I’ll give it a shot later today. Thanks!
Just wondering what MCP servers you guys integrated and feel like has dramatically changed your success. Also, what other methodologies do you work with to achieve good results? Conversely what has been a disappointment and you've decided not to work with anymore?
I am just trying to get a sense of the tools or hacks I am missing and collectively good for everyone to assess too :-)
im not a coder or anything, just playing around for my own fun, so sorry if its a stupid question
but im trying to move and use cc on windows rather than wsl, any mcp im trying to install, is failing to connect
installasion command for example: claude mcp add playwright npx u/playwright/mcp@latest
any idea why? is there a problem with mcps support on windows for now?
Are there any cool "MCPs" or a specific workflow you use to make it even better?
I have never heard of or used Playwrite until I just had issues with my Nextjs project using Tailwind 4 but CC was doing version 3 related implementations.
Suddenly Claude Code installed Playwrite & instead of just checking the code it literally looks at your site through tests to confirm: Hey the problem this dude has been saying is a problem, guess what it doesn't work!!!
Here's a link to it: https://playwright.dev/
Sorry if I sound new, but I'm not I've been study & coding for years I just never heard of this especially to use with Claude Code.
Is everyone using this already??
Drop something that has changed your life
I am doing a website migration from one CMS to the other, and have started using Claude to automate a lot of it.
However, I'm looking for a browser agent that lets Claude explore a website I give it.
Any recommendations? I largely just need content. I know Playwright is widely recommended but not too sure if its overkill, since it eats up a lot of tokens.
Three months ago I switched from Cursor to Claude Code CLI. Thought I'd share what my setup looks like now and get some feedback on what I might be missing.
Context: I'm a non-CS background dev (sales background, learned to code 2 years ago) building B2B software in a heavily regulated space (EU manufacturing, GDPR). So my setup is probably overkill for most people, but maybe useful for others in similar situations.
The Setup
Core:
- Claude Code CLI in terminal (tried the IDE plugins, prefer the raw CLI)
- Max subscription (worth it for the headroom on complex tasks)
- Windows 11 + PowerShell (yes, really)#
MCP Servers (4 active):
| Server | Why I use it |
|---|---|
| filesystem | Safer file operations than raw bash |
| git | Quick rollbacks when the agent breaks things |
| sequential-thinking | Forces step-by-step reasoning on complex refactors |
| playwright | E2E test automation |
Browser Automation:
- Google Antigravity for visual testing
- Claude for Chrome (can control it from CLI now, game changer)
Custom Skills I Wrote
This is where it gets interesting. Claude Code lets you define custom skills that auto-activate based on context. Here's what I built:
| Skill | Trigger | What is does |
|---|---|---|
| code-quality-gate | Before any deploy | 5-stage checks: pre-commit → PR → preview → E2E → pro |
| strict-typescript-mode | Any .ts/.tsx file | Blocks any, enforces generics, suggests type guards |
| multi-llm-advisor | Architecture decisions | Queries Gemini + OpenAI for alternative approaches |
| secret-scanner | Pre-commit hook | Catches API keys, passwords, tokens before they hit git |
| gdpr-compliance-scanner | EU projects | Checks data residency, PII handling, consent flows |
| gemini-image-ge | On demand | Generates images via Gemini API without leaving CLI |
The multi-llm-advisor has been surprisingly useful. When Claude suggests an architecture, I have it ask Gemini and GPT-4 "what would you do differently?" Catches blind spots I'd never notice.
The Secret Sauce: CLAUDE.md
This file changed everything. It's ~500 lines of project-specific instructions that the agent reads on every prompt. Key sections:
No-Touch Zones
NEVER modify without explicit permission:
- api/auth.ts (authentication)
- api/analyze.ts (core business logic)
- vercel.json (deployment config)
Without this, the agent would "helpfully" refactor my auth code while fixing an unrelated bug. Ask me how I know.
2. Quality Gates
Before ANY commit:
npm run build - MUST succeed
npm run test - All tests pass
npx tsc --noEmit - Zero TypeScript errors
The agent checks these automatically now. Catches ~80% of issues before I even review.
3. Regression Prevention Rules
- ONE change at a time
- List all affected files BEFORE writing code
- If touching more than 3 files, stop and ask
This stopped the "I'll just clean up this code while I'm here" behavior that caused so many bugs.
What Actually Changed My Workflow
"Vibe coding" with guardrails
I describe what I want in natural language. The agent builds it. But the CLAUDE.md rules prevent it from going off the rails. Best of both worlds.
2. The iteration loop
Agent writes code → runs tests → tests fail → agent reads error → fixes → repeat. I just watch until it's green or stuck. Most features ship without me writing a line.
3. Browser-in-the-loop testing
Agent makes UI change → opens Chrome → visually verifies → iterates. Still fails ~30% of the time but when it works, it's magic.
4. Fearless refactoring
With git MCP + quality gates + no-touch zones, I let the agent do refactors I'd never attempt manually. Worst case, git reset --hard and try again.
What Still Sucks, being honest here:
- Setup time: Took 2-3 weeks to dial in. Not beginner friendly at all.
- Browser automation reliability: Antigravity rate limits, Claude for Chrome loses context, ~30% failure rate on complex flows.
- Token usage: Max helps but big refactors can still burn through quota fast.
- Windows quirks: Some MCP servers assume Unix. Had to patch a few things.
- Agent overconfidence: Sometimes it says "done!" when it clearly isn't. Trust but verify.
Questions for This Community
MCP servers: Anyone using others I should try? Especially interested in database or API testing servers.
Preventing scope creep: How do you stop the agent from "improving" code you didn't ask it to touch? My no-touch zones help but curious about other approaches.
Browser automation: Anyone found something more reliable than Antigravity for visual testing?
CLAUDE.md patterns: Would be curious to see how others structure theirs. Happy to share my full file if there's interest.
TL;DR: Claude Code CLI + MCP servers + custom skills + strict CLAUDE.md rules = actual production-ready code from "vibe coding". Took weeks to set up but now I ship faster than I ever did manually. :)
