Mantis is an open-source MCP browser that gives AI agents a real browser but renders pages as short numbered text instead of screenshots. Install in two commands:
npx -y -p mantis-browser mantis install
claude mcp add mantis -- npx -y -p mantis-browser mantis-mcp
Benchmarked against Playwright MCP and screenshots: on long tasks, 30-45% fewer tokens than Playwright and 50% fewer than screenshots, faster, with same or better accuracy. Repo: perzianhq/mantis.
