MCP server that lets AI agents build, run, inspect, and publish browser extensions. 30 tools for scaffolding, live DOM inspection, log streaming, and store-ready builds across Chrome, Edge, Firefox, Safari, and every Chromium- or Gecko-based browser.

Code-only MCP server: no hosted endpoint, so you install and run it yourself. It is not probed, graded or counted in our reachability statistics.
