mobile-next/mobile-mcp (8.2k stars, Apache-2.0) connects iOS simulators and real devices plus Android emulators and real devices to any MCP client, including Claude Code, Codex, Gemini and Copilot. Its first principle is accessibility-first: read the native accessibility tree instead of screenshots, no vision model and no image tokens, falling back to screenshots with coordinates only when necessary. Roughly 30 tools in seven groups cover device management, remote devices through Mobile Next Cloud, app management, screen interaction with recording, input and navigation, logs and crashes, and batch commands that compress N rounds into one. The README examples are all cross-app long-horizon tasks, the hardest class for mobile agents.
