MCP-Playwright-Demo
🚀 AI + MCP + Playwright Tool
Where AI stops talking and starts interacting with real web pages.
This project demonstrates how MCP (Model Context Protocol) allows an AI to safely control a browser via Playwright — clicking buttons, filling forms, reading content, and executing JavaScript — without giving direct system access.
✨ Why This Matters
AI can interact with real web pages ✅
Controlled, permission-based automation ✅
Today it’s a demo for simple browsing tasks, tomorrow it can handle QA workflows, scraping, testing, and cloud automation ✅
| Component | Role |
|---|---|
playwright_mcp.py |
MCP server exposing browser tools |
| MCP | Bridge that lets AI call async Python functions |
| AI Client | The “brain” that triggers web interactions |
@mcp.tool() async def navigate(url: str) -> str: """Navigate to the given URL""" await _ensure_browser() await page.goto(url, wait_until="domcontentloaded") title = await page.title() return f"Navigated to: {url}\nPage title: {title}"
Other tools include:
click(selector) → click elements
fill(selector, value) → fill input fields
evaluate_js(script) → run JS on the page
get_text() → get page content
get_current_url() → get URL
get_page_title() → get title
