What its author says it does

Browser automation via Playwright MCP through mcporter. Use when you need to navigate pages, extract data, take screenshots, interact with UI elements, or scrape web content. All tools called via mcporter to avoid context pollution.

Playwright (MCPorter)

All tools called via mcporter:

npx mcporter call playwright.TOOL_NAME [args]

Core Workflow

Navigate

npx mcporter call playwright.browser_navigate url:"https://example.com"

Snapshot (preferred for data extraction — better than screenshot)

npx mcporter call playwright.browser_snapshot
# Save to file to avoid flooding context:
npx mcporter call playwright.browser_snapshot filename:"snapshot.md"

Screenshot

npx mcporter call playwright.browser_take_screenshot type:png filename:"page.png"
npx mcporter call playwright.browser_take_screenshot type:png fullPage:true filename:"full.png"

Wait for dynamic content

npx mcporter call playwright.browser_wait_for text:"Loaded"
npx mcporter call playwright.browser_wait_for time:2

Click (use ref from snapshot)

npx mcporter call playwright.browser_click ref:"e123" element:"Submit button"

Type into field

npx mcporter call playwright.browser_type ref:"e45" text:"search query" submit:true

Run arbitrary Playwright code

npx mcporter call playwright.browser_run_code \
  code:"async (page) => { return await page.title(); }"

Evaluate JS in page context

npx mcporter call playwright.browser_evaluate \
  function:"() => Array.from(document.querySelectorAll('table tr')).map(r => r.innerText)"

Common Patterns

Scrape table data

npx mcporter call playwright.browser_navigate url:"https://site.com/data"
npx mcporter call playwright.browser_wait_for time:2
npx mcporter call playwright.browser_snapshot filename:"raw.md"

Login then scrape

npx mcporter call playwright.browser_navigate url:"https://site.com/login"
npx mcporter call playwright.browser_snapshot
# use refs from snapshot for fields
npx mcporter call playwright.browser_type ref:"REF" text:"[email protected]"
npx mcporter call playwright.browser_type ref:"REF" text:"password" submit:true
npx mcporter call playwright.browser_wait_for text:"Dashboard"

Tab management

npx mcporter call playwright.browser_tabs action:list
npx mcporter call playwright.browser_tabs action:new
npx mcporter call playwright.browser_tabs action:select index:0

Network inspection

npx mcporter call playwright.browser_network_requests includeStatic:false

Anti-Patterns

❌ Don't call browser_snapshot without filename: when output is large — floods context ❌ Don't load playwright MCP in .claude.json alongside this skill — mcporter only ❌ Don't add --headless to mcporter.json for UI testing — defeats the purpose
