Brocogni is an MCP server that pre-computes semantic Playwright selectors for AI agents, replacing fragile CSS selectors with self-healing fallback chains based on ARIA roles and relational XPath. It reduces token usage and cost by filtering noisy HTML down to actionable nodes, and its benchmark shows significant savings over naive browser automation approaches, making it a practical tool for AI-driven browser testing and agentic browsing.

Target audience: backend devs, devops, ai engineers
