Implements MCP server that connects directly to Chrome via Chrome DevTools Protocol (CDP), eliminating middleware overhead while maintaining real browser sessions and login state across parallel tabs. Includes 27 harness subsystems—hint engine with 30+ rules, outcome classification, pattern learning, and DOM compression achieving 15x token efficiency—that guide AI agents and prevent costly error cascades. Achieves ~300MB memory for 20 parallel sessions versus 5GB+ for traditional approaches, while remaining invisible to bot detection and enabling authenticated cross-site operations.
