Ascended Browser: an open-source browser MCP giving Codex CLI and Claude Code QA hands
Useful-Tune-1556 · reddit · 2026-10-06
Ascended Browser is an open-source browser MCP for coding agents: install, add MCP config (Claude Code, Codex, opencode configs included), and your agent can click through your app, read back changes, inspect console logs and network requests, and report breakage. Notably useful over SSH on Linux where Codex CLI lacks a built-in browser. Limits: Linux-tested only, 700MB first browser download, Python 3.11+, not yet benchmarked against Playwright/Chrome DevTools MCP.
