BrowserClaw
High-efficiency Chrome browser automation MCP platform that pairs an MV3 extension with a local native bridge so agents can control the user's active authenticated browser instead of a throwaway profile. It exposes roughly fifty-two tools, compact DOM and accessibility-tree views, network request helpers, chained JavaScript execution, visual fallback, tab lifecycle management, and a local HTTP MCP endpoint. Public GitHub repository created September 10, 2026.
