Microsoft Edge exposes the Chromium DevTools Protocol for remote page inspection and automation. For Codex, 1 route is explicitly documented by the integration maintainer.
Node.js and a supported browser or Playwright-managed browser installation; existing Chrome/Edge sessions need the extension route.
Can Codex control all of Microsoft Edge?
The sources establish the capabilities listed above, not complete application coverage. Check each bridge’s limitations and your application version before starting.
Which setup should I use?
Choose a route that explicitly documents Codex and matches your environment. Start with the maintainer’s setup guide and a disposable project copy. Shared MCP support alone is listed as an inference.
