Phonebox MCP

Phonebox provides cloud Android phones that AI agents can see and control. The MCP server allows agents to read the screen as a numbered list of elements, tap by label, type, swipe, install APKs, open apps, and move files. It is designed for testing Android builds, operating apps without APIs, and building agent products on phones.

Endpoint and access

OAuth sign-in: the first time you connect, your client opens the vendor's own authorization prompt in a browser.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http phonebox-mcp https://phonebox.dev/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add phonebox-mcp --url https://phonebox.dev/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable phonebox-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "phonebox-mcp": {
      "url": "https://phonebox.dev/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "phonebox-mcp": {
      "type": "streamableHttp",
      "url": "https://phonebox.dev/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start phonebox-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "phonebox-mcp": {
      "type": "http",
      "url": "https://phonebox.dev/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http phonebox-mcp https://phonebox.dev/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.
Claude Desktop configuration
{
  "mcpServers": {
    "phonebox-mcp": {
      "url": "https://phonebox.dev/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "phonebox-mcp": {
      "serverUrl": "https://phonebox.dev/mcp"
    }
  }
}
