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

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).

• adb on your PATH (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 on curl — a prefix on curl is ignored. On Windows, set $env:… before the irm.

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

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.)

1. Open the Quash desktop app and sign in.

2. Go to Settings → Integrations.

3. Click Generate token (or regenerate to replace an existing one).

4. 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):

1. Open Settings → Tools → AI Assistant → Model Context Protocol (MCP).

2. Easiest: click Import from Claude — since the installer already registered Quash in Claude Desktop, the quash server is pulled in automatically.

3. 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"
         }
       }
     }
   }

4. 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 auth with mode google."

  • Token: "Use Quash, run auth with my token qsh_…."

Check status anytime with the about / configure tools.

6. Prepare the device

1. Connect — "Use Quash, connect." It detects the device (or lists them if several), warms the engine, and runs a setup health check.

2. Finish setup for that device type:

   • Android — if connect reports "Portal not ready", run setup_portal: it installs the on-device Quash Portal app and enables its accessibility service (idempotent). If the device blocks it, it returns manual_required with 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 with configure 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.

7. Using the tools

Ask the agent in plain language; it calls these tools:

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 returns manual_required, enable Mahoraga Portal under Settings → Accessibility.

• adb / device not found → install Android platform-tools, ensure adb is on PATH (Windows: set ANDROID_HOME), and that the device shows under adb devices.

• iOS setup_device signing fails (macOS) → set your team with configure 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 refresh QUASH_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 execute result's warning field.

• 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.
