Your agent reaches Android over one MCP URL.

Most Android MCP servers run on your computer and drive a device through adb, so you install the Android SDK and start an emulator first. Ramus is a remote MCP server: your agent adds one URL, you sign in, and it gets an Android emulator in the cloud.

Connect.

Add the server, then sign in with your Ramus account when the client asks. There is no key to paste.

# Claude Code
claude mcp add --transport http ramus https://api.ramus.dev/api/mcp

# Codex
codex mcp add ramus --url https://api.ramus.dev/api/mcp

# Cursor: ~/.cursor/mcp.json
{ "mcpServers": { "ramus": { "url": "https://api.ramus.dev/api/mcp" } } }

In ChatGPT, open Apps, search for Ramus and choose Connect. Any other client that speaks Streamable HTTP can use the same URL, with sign-in or an API key sent as a bearer token. See Connect an agent.

What your agent can do.

  • Start a device

    android_start_session starts an emulator from an APK, an app Ramus already has or a pull request. android_install_app installs a new build on a running device. android_upload_apk gives an agent with a shell a one-time upload for a local file.

  • Read the screen

    android_snapshot returns the screen as elements, each with a ref. android_screenshot returns the picture when the elements are not enough.

  • Act and check

    android_tap takes visible text or a ref, and can name the text it expects. Each action returns the screen it led to, so the agent decides the next step from it. A ref from an older screen is refused.

  • Hand it over

    Every device comes with a watch link. android_share_session makes more, including one that gives each person their own device. android_list_feedback and android_get_feedback read the notes people send back.

Android-MCPWhere the device runs:A device or emulator that adb on your computer reaches2What you install:Python 3.13, uv and adb2Sign-in:None; it runs over stdio2
Maestro MCPWhere the device runs:Your computer; cloud tools submit test runs to Maestro Cloud3What you install:The Maestro CLI, which needs Java 17 or later4Sign-in:None locally; Maestro sign-in for cloud tools3
LimrunWhere the device runs:Limrun's cloud: Android 14 and 15 emulators, iOS simulators5What you install:Nothing for the remote server6Sign-in:Limrun account, or an API key6
Mobile Next CloudWhere the device runs:Mobile Next's cloud: real Android and iOS devices7What you install:Nothing for the remote server8Sign-in:Mobile Next account8
BrowserStack MCPWhere the device runs:BrowserStack's real-device cloud9What you install:Nothing for the hosted server; the local server uploads apps from your machine10Sign-in:BrowserStack account; App Live tools need an App Live license10

A local server is the right choice when you already run an emulator or keep a phone plugged in, and want nothing to leave your machine. A remote one suits agents without the Android SDK: cloud agents, ChatGPT, and machines where you would rather not run an emulator.

Questions.

Do I need adb or Android Studio?

No. The device runs in the cloud and your agent reaches it over MCP. Only the CLI's adb tunnel and hot-reload loop use Android tools on your computer.

Can the agent upload an APK from my machine over MCP?

Yes, if the agent has a shell. android_upload_apk returns a one-time curl command that uploads the file, and android_start_session or android_install_app then uses it. In ChatGPT, attach the APK to a message.

Which clients work?

Claude Code, Codex, Cursor and ChatGPT sign in over MCP. Any other client that supports Streamable HTTP can connect, with sign-in or an API key.

Does it support iOS?

No. Ramus runs Android emulators only.

What does it cost?

Free includes 30 minutes a month. Pro is $10 a month for unlimited minutes and two devices at once. Sessions your agent starts count toward your plan.
