Drengr

Eyes and hands for AI agents on mobile devices.

Drengr is an MCP server that gives AI agents (Claude, GPT, Gemini) the ability to see, tap, type, and navigate mobile apps — Android and iOS.


Install

npm install -g drengr

Or run without installing:

npx drengr

Or via shell script:

curl -fsSL https://drengr.dev/install.sh | bash

Quick Setup

# Check your system
drengr doctor

# Configure your MCP client (Claude Desktop, Claude Code, Cursor, etc.)
drengr setup

Add to Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "drengr": {
      "command": "drengr",
      "args": ["mcp"]
    }
  }
}

Add to Claude Code

claude mcp add drengr -- drengr mcp

Add to Cursor

Add to .cursor/mcp.json in your project:

{
  "mcpServers": {
    "drengr": {
      "command": "drengr",
      "args": ["mcp"]
    }
  }
}

What Drengr does

  • 3 MCP tools: drengr_look (observe screen), drengr_do (take action), drengr_query (ask questions)
  • Android & iOS — ADB for Android, simctl for iOS, Appium for cloud devices
  • Vision-first — sees your app like a human via annotated screenshots
  • Text mode — ~300 tokens per screen instead of 100KB images
  • Situation reports — after every action: what changed, what's new, is it stuck?
  • Screen exploration — auto-maps your app's navigation graph
  • Network capture — sees HTTP calls during each action
