Quash MCP
The Quash MCP server lets an AI agent (Claude Code, Claude Desktop, Cursor, …) drive real mobile-app automation on a connected device: run natural-language test tasks, generate test cases from prompts/docs/repos, manage apps & builds, and pull back streamed runs and reports — all powered by the Quash (mahoraga) automation engine.
This guide covers installing it on macOS or Windows, wiring it into your agent, generating an API token, preparing a device, and using every tool.
Platform support
| Platform | Android | iOS (simulator + physical) | Installer |
|---|---|---|---|
| macOS (Apple Silicon) | ✅ | ✅ | install.sh (curl … | sh) |
| Windows (x64) | ✅ | ❌ (Apple toolchain is macOS-only) | install.ps1 (irm … | iex) |
iOS automation needs Xcode / WebDriverAgent /
devicectl/iproxy, which exist only on macOS — so the iOS tools (setup_simulator,setup_device) appear in the macOS build only. Windows is Android-only. Linux x86_64 can be built from source but isn't published as a release binary.
1. Prerequisites
- macOS 13+ (Apple Silicon) or Windows 10/11 (x64).
adbon yourPATH(Android platform-tools) for Android automation. On Windows the installer also detects%LOCALAPPDATA%\Android\Sdk.- A device: an Android device/emulator (USB debugging on), or — on macOS — an iOS simulator or a physical iPhone (Developer Mode on, trusted, USB).
- A Quash account to authenticate (step 3 for a token, or browser sign-in in step 5).
- For iOS on macOS: Xcode installed (for the WebDriverAgent build).
The installer also downloads the automation engine, a bundled test-generation component, and the on-device Android Portal APK.
2. Install
One command installs everything and auto-registers the server in every supported agent config it finds (Claude Code, Claude Desktop, Cursor). Pick your platform:
macOS
curl -fsSL https://raw.githubusercontent.com/Oscorp-HQ/quash-mcp-releases/main/install.sh | sh
Windows (PowerShell)
irm https://raw.githubusercontent.com/Oscorp-HQ/quash-mcp-releases/main/install.ps1 | iex
This installs the latest release into ~/.quash (macOS) / %USERPROFILE%\.quash
(Windows) and connects to Quash production automatically — no backend URL to
configure.
Cursor users: after running the installer above (needed for the engine), you can one-click add the MCP server to Cursor:
(The installer already auto-registers Cursor, so this is only needed if you skipped that or removed the entry.)
Options (env vars)
macOS gotcha: environment variables must go on the piped
sh, not oncurl— a prefix oncurlis ignored. On Windows, set$env:…before theirm.
macOS — wire your token in / pin a version:
# Token at install time (recommended — see step 3):
curl -fsSL https://raw.githubusercontent.com/Oscorp-HQ/quash-mcp-releases/main/install.sh | QUASH_API_TOKEN=qsh_xxxxxxxx sh
# Pin a specific version:
curl -fsSL https://raw.githubusercontent.com/Oscorp-HQ/quash-mcp-releases/main/install.sh | QUASH_VERSION=v1.1.0 sh
Windows — same, via $env::
$env:QUASH_API_TOKEN = "qsh_xxxxxxxx"
irm https://raw.githubusercontent.com/Oscorp-HQ/quash-mcp-releases/main/install.ps1 | iex
| Env var | Default | Purpose |
|---|---|---|
QUASH_API_TOKEN | (unset) | API token; if set, the MCP signs in automatically on startup |
QUASH_VERSION | latest | Release tag to install |
QUASH_BACKEND_URL | production | Override the backend (staging/local) |
QUASH_FORCE | 0 | 1 forces a full reinstall even if the version matches |
Re-running the installer is safe: it refreshes config and, with QUASH_FORCE=1,
reinstalls the binaries. Reconnecting the agent does not update the server —
only re-running the installer does.
3. Generate an API token from the Quash app
The token lets the MCP authenticate without a browser. (Prefer not to manage a token? Skip to step 5 and use Google sign-in instead.)
- Open the Quash desktop app and sign in.
- Go to Settings → Integrations.
- Click Generate token (or regenerate to replace an existing one).
- Copy the token — it starts with
qsh_. It's shown once; store it safely.
Generating a new token invalidates the previous one, so update it everywhere
you use it. The token is scoped to the organization you're signed into and is
stored only in your agent's MCP config env block — never passed through the chat.
4. Add it to your agent
The installer auto-registers the quash server, so usually there's nothing to do.
To verify or add it manually, the entry looks like this — use the paths for your
platform:
macOS
{
"mcpServers": {
"quash": {
"type": "stdio",
"command": "/Users/<you>/.quash/bin/quash-mcp",
"env": {
"QUASH_SIDECAR_CMD": "/Users/<you>/.quash/sidecar/quash-sidecar/quash-sidecar",
"QUASH_TEST_GEN_AGENT_CMD": "/Users/<you>/.quash/test-gen-venv/bin/python -m test_gen_agent",
"QUASH_API_TOKEN": "qsh_xxxxxxxx"
}
}
}
}
Windows
{
"mcpServers": {
"quash": {
"type": "stdio",
"command": "C:\\Users\\<you>\\.quash\\bin\\quash-mcp\\quash-mcp.exe",
"env": {
"QUASH_SIDECAR_CMD": "C:\\Users\\<you>\\.quash\\sidecar\\quash-sidecar\\quash-sidecar.exe",
"QUASH_API_TOKEN": "qsh_xxxxxxxx",
"ANDROID_HOME": "C:\\Users\\<you>\\AppData\\Local\\Android\\Sdk"
}
}
}
}
Config file locations: Claude Code → ~/.claude.json (macOS) /
%USERPROFILE%\.claude.json (Windows); Claude Desktop →
~/Library/Application Support/Claude/claude_desktop_config.json /
%APPDATA%\Claude\claude_desktop_config.json; Cursor → ~/.cursor/mcp.json /
%USERPROFILE%\.cursor\mcp.json.
After editing config, restart the agent (or /mcp → reconnect in Claude Code).
JetBrains IDEs (IntelliJ IDEA, PyCharm)
JetBrains AI Assistant supports MCP over stdio. After running the installer (step 2):
-
Open Settings → Tools → AI Assistant → Model Context Protocol (MCP).
-
Easiest: click Import from Claude — since the installer already registered Quash in Claude Desktop, the
quashserver is pulled in automatically. -
Or add manually: click Add, then paste this JSON (JetBrains does not expand environment variables, so use absolute paths — replace
<you>with your username):macOS
{ "mcpServers": { "quash": { "command": "/Users/<you>/.quash/bin/quash-mcp", "env": { "QUASH_SIDECAR_CMD": "/Users/<you>/.quash/sidecar/quash-sidecar/quash-sidecar", "QUASH_TEST_GEN_AGENT_CMD": "/Users/<you>/.quash/test-gen-venv/bin/python -m test_gen_agent" } } } }Windows
{ "mcpServers": { "quash": { "command": "C:\\Users\\<you>\\.quash\\bin\\quash-mcp\\quash-mcp.exe", "env": { "QUASH_SIDECAR_CMD": "C:\\Users\\<you>\\.quash\\sidecar\\quash-sidecar\\quash-sidecar.exe", "QUASH_TEST_GEN_AGENT_CMD": "C:\\Users\\<you>\\.quash\\test-gen-venv\\Scripts\\python.exe -m test_gen_agent" } } } } -
Click OK → Apply to start the server.
Android Studio: its agent (Gemini Agent Mode) currently supports MCP over HTTP/Streamable only, not stdio, so the config above does not apply there yet.
5. Authenticate
- If you set
QUASH_API_TOKEN, the server signs in automatically on startup. - Otherwise, ask the agent to authenticate:
- Google (browser): "Use Quash, run
authwith modegoogle." - Token: "Use Quash, run
authwith my tokenqsh_…."
- Google (browser): "Use Quash, run
Check status anytime with the about / configure tools.
6. Prepare the device
- Connect — "Use Quash,
connect." It detects the device (or lists them if several), warms the engine, and runs a setup health check. - Finish setup for that device type:
- Android — if
connectreports "Portal not ready", runsetup_portal: it installs the on-device Quash Portal app and enables its accessibility service (idempotent). If the device blocks it, it returnsmanual_requiredwith the steps for Settings → Accessibility. - iOS simulator (macOS) — run
setup_simulator: builds + launches WebDriverAgent for the booted simulator (no signing needed). - iOS physical iPhone (macOS) — run
setup_device: resolves your Apple Developer signing team (set it withconfigure signing_team=<TEAMID>, or it's auto-detected from your keychain), builds + signs WebDriverAgent, starts the USB tunnel, and launches it. Requires Xcode, Developer Mode on, and the iPhone trusted over USB.
- Android — if
7. Using the tools
Ask the agent in plain language; it calls these tools:
| Tool | What it does | Platform |
|---|---|---|
about | Server name, running version, latest release, update command | all |
auth | Sign in (google browser flow, or token) | all |
connect | Detect/select a device; health-check adb, Portal, engine, auth | all |
configure | View/change execution + test-gen settings (model, temperature, max steps, vision, signing_team) | all |
setup_portal | Install the Android Portal app + enable accessibility (idempotent) | all |
setup_simulator | Build + launch WebDriverAgent for a booted iOS simulator | macOS |
setup_device | Sign + launch WebDriverAgent on a physical iPhone over USB | macOS |
execute | Run a natural-language test task on the device (streams progress) | all |
generate_test_cases | Generate test cases from a prompt, local files, or a git repo | all |
usage | Current plan, remaining minutes, feature limits | all |
list_apps | List apps in your org | all |
builds | List builds for an app (version, tag, installable) | all |
install_build | Download a build's APK and install it on the device | all |
runs | Browse recent runs, or fetch one run's full report + share link | all |
test_cases / suites | Browse test cases and suites | all |
Typical first session:
"Use Quash: connect, then setup_portal if needed." # Android
"Use Quash: connect, then setup_simulator." # iOS simulator (macOS)
"Run this on the device: open Settings and turn on Airplane mode."
"Show me the report for that run."
"Generate test cases for https://github.com/acme/my-app."
8. Updating
Re-run the installer for your platform (macOS curl … | sh, Windows irm … | iex),
then restart the agent. Confirm with the about tool — it reports the running
version and whether a newer release exists.
9. Troubleshooting
- "Portal not ready" (Android) → run
setup_portal. If it returnsmanual_required, enable Mahoraga Portal under Settings → Accessibility. - adb / device not found → install Android platform-tools, ensure
adbis onPATH(Windows: setANDROID_HOME), and that the device shows underadb devices. - iOS
setup_devicesigning fails (macOS) → set your team withconfigure signing_team=<TEAMID>, ensure your Apple ID is signed into Xcode → Settings → Accounts (with an Apple Development certificate in the keychain), and the iPhone is in Developer Mode + trusted. - Session expired / not authenticated → re-run
auth, or refreshQUASH_API_TOKEN(generating a new token invalidates the old one). - A run isn't visible in the app → the run's org must match the app's org;
check the
executeresult'swarningfield. - macOS Gatekeeper warning → public binaries are ad-hoc signed; if blocked, allow them under System Settings → Privacy & Security.
- Windows SmartScreen / Defender → unsigned binaries may prompt "Windows
protected your PC"; click More info → Run anyway, or add a Defender
exclusion for
%USERPROFILE%\.quash.
