Pagerunner — The Browser Layer That Learns
Launches a real Chrome instance via CDP and wires it to Claude through MCP stdio, exposing 38 tools for navigation, clicking, typing, screenshots, and JavaScript execution. The key hook is that it uses your actual Chrome profiles with all their cookies, saved passwords, and login sessions already intact. Includes PII anonymization to scrub personal data before sending DOM content back to the LLM, plus snapshot/restore for persisting page state across conversations. Built in Rust with stealth mode to avoid bot detection. Useful when you need Claude to interact with sites where you're already authenticated or when scraping public data without managing session state manually.
