How builders describe it

Browser automation where an LLM plans and Jev (Typesafe System One) decides. Library, CLI and MCP server.
A JavaScript browser library, CLI, and MCP server that lets a calling agent specify one outcome while Jev selects browser actions and targets from structured page observations.
Hi everyone, this is my approach for browser automation. And I find a lot of potential for jev doing this. Let me know any idea or discuss with me in DM is welcomed. Thanks for letting me have early access!

The decision Jev makes

Pick the next click, field or navigation from the legal actions on screen.

Where it fits

Browser agents need to choose an action on every step. With Jev each step is a choice from the actions actually available on the page, which keeps agents fast and on the rails. All 193 agents & browsers projects →
