Mobile Harness: Open-source agent harness for iOS and Android device control

LinkTool

Mobile Harness is an open-source framework powered by mobilerun-core that gives AI agents a unified API and consistent control path across local and cloud-based mobile devices.

Key points

  1. Acts as connective tissue between AI agents (such as Claude Code or Codex) and mobile device control surfaces.
  2. Powered by mobilerun-core to deliver a unified Mobilerun facade for both Android and iOS.
  3. Markdown-first design: AGENTS.md directs agents to minimal, context-specific platform guides, app cards, and recovery procedures.
  4. Scales from a single local handset to multi-device cloud fleets using the same control path.

Why it matters

Allowing AI agents to operate real mobile hardware reliably requires consistent interfaces across operating systems. Mobile Harness streamlines device interaction and context management for agent environments with shell access.

Analysis

The project emphasizes context efficiency for AI runtimes. By relying on modular Markdown guides rather than heavy tooling wrappers, agents load only the instructions required for a specific task or OS. Built-in capability checks help prevent unsupported actions across varying device environments.
