Give Claude Code web access: Playwright MCP, a scraping MCP, or both

# The same three tasks in Claude Code with Playwright MCP, with Skryp's MCP server, and with both:
# did it get the answer, how many turns, how many tokens, what it cost, how long it took.
# Needs Claude Code, Node.js (for npx) and SKRYP_API_KEY. Each run is a fresh session in a scratch folder with
# Claude Code's built-in tools switched off (--tools ""), so the MCP servers are the only way to the web.
# timeout: 2400
