Eyes, ears, and hands for AI-assisted mobile development.
Quern is a local debug server that lets AI coding agents — Claude Code, Cursor, Windsurf, and others — actually see what your app is doing. Logs, network traffic, crash reports, screenshots, UI state: instead of guessing from stack traces and stale error messages, your agent gets live, structured access to everything happening on the device.
No cloud. No telemetry. Just a daemon on your Mac that bridges the gap between "build succeeded" and "it actually works."
Supports iOS simulators, physical iOS devices (via WebDriverAgent), Android emulators, and physical Android devices.
Simulator / Device
│
Quern (localhost:9100)
├── Log capture (device, simulator, crash reports, build output)
├── Network proxy (intercept, mock, replay HTTP traffic)
├── Device control (boot, screenshot, tap, swipe, type)
│
├── HTTP API ──→ Any tool or script
└── MCP tools ──→ Claude Code, Cursor, etc.
adb via Homebrewcurl -fsSL https://quern.dev/install.sh | bash
This downloads the latest release to ~/.local/share/quern, creates a virtualenv, installs dependencies, checks system tools, registers the MCP server with Claude Code, installs a Claude Code pre-commit checklist hook (see below), and adds quern to ~/.local/bin on your PATH.
Setup also installs a Claude Code PreToolUse hook into ~/.claude/settings.json that surfaces a short checklist whenever an agent runs git commit in a project that uses Quern (signaled by a .quern/knowledge/ directory at the project root). The reminder covers KB drift, landmark verification, and other discipline that's easy to forget when committing app or KB changes. It stays silent in projects that don't use Quern.
To re-install or refresh the hook (for example after updating Quern), run quern install-precommit-hook. To disable it, remove the matching entry from ~/.claude/settings.json under hooks.PreToolUse.
<details> <summary>Manual install</summary>
Download the latest release tarball from GitHub Releases, then:
mkdir -p ~/.local/share
tar -xzf quern-*.tar.gz -C ~/.local/share
mv ~/.local/share/quern-* ~/.local/share/quern
cd ~/.local/share/quern
python3 -m server setup
.venv/bin/python -m server mcp-install
</details>
quern uninstall
Removes Homebrew packages, pipx packages, MCP registrations, the wrapper script, and the virtualenv. Only removes packages that were installed by quern setup — pre-existing tools (like Node.js) are left untouched. The source code directory is preserved; the command prints instructions to remove it if desired.
cd mcp && npm run build
Once the server is installed and the MCP is registered, open your mobile project with your AI coding assistant (Claude Code, Cursor, etc.) and just ask it to do things:
"Boot an iPhone 16 simulator, make sure the proxy is capturing traffic, then build and install my app. Log in with testuser / password123 and give me a summary of all the API calls you see during login."
The agent will use Quern's MCP tools to boot the simulator, configure the proxy, install your app, drive the UI to log in, and then query the captured network traffic — all without you touching the simulator or pasting logs into chat.
Other things you can ask:
.venv/bin/pytest tests/ -v
For writing scripts that perform repeatable actions available in Quern. These can augment or replace XCUITests if you wish
```bash API_KEY=$(cat ~/.quern/api-key)
All endpoints require Authorization: Bearer <key> except /health.
