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

After install, run drengr build-runner once (interactive terminal) to build the iOS runner. Re-run after iOS or Xcode upgrades.

Quick Setup

# Check your system
drengr doctor

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

Add to Claude Desktop

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

Add to Claude Code

Add to Cursor

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

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

Uninstall

drengr uninstall           # removes data + MCP configs

Removes the binary, all local data (~/.drengr/), and cleans drengr from your MCP client configs. Leaves nothing behind.
