JevSim runs on your own machine — the client starts it, so there is no endpoint to ping. Last commit 21 Sep 2026.
Run verified iOS and Android UI workflows in one agent tool call with Jev.
Today is the operative word: we check JevSim every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start:
TYPESAFE_API_KEY (TypeSafe API key for semantic selection. Exact-identifier workflows need no key.), JEVSIM_MODEL (TypeSafe selection model.), JEVSIM_XCODE_COMMAND (iOS only: XcodeBuildMCP executable. Use an absolute path if needed.), JEVSIM_XCODE_ARGS (iOS only: JSON array of XcodeBuildMCP arguments.), JEVSIM_ANDROID_APPIUM_URL (Android only: separately running Appium 3/UIAutomator2 server on loopback.), JEVSIM_ADB_COMMAND (Android only: adb executable. Use an absolute path if needed.).
