Vercel Labs has open-sourced agent-browser, an AI browser automation powerhouse.
Previously, when doing browser automation, we mostly used MCPs like Playwright.
But MCP is just too difficult to use! I bet you’re as fed up as I am with all the anti-human operations of MCP:
Configure it once on Claude Code, then reconfigure it again on Cursor. After finishing the JSON format configuration, you have to convert it to TOML on Codex.
After each configuration, you need to restart. Once the restart is complete, you discover an extra comma was added during merging, so you have to restart again.
After finally getting the installation error-free, Codex throws an MCP connection failure error at runtime. After spending ages troubleshooting and finally fixing it, a dozen MCPs immediately blow up the window context, and token warnings appear after just a few exchanges.
