iOS Simulator MCP Server

Example Use Cases

• 1

  Programmatically boot or shut down specific iOS simulator instances (by UDID) as part of automated testing or environment setup.

• 2

  Install, launch, terminate apps, and take screenshots on iOS simulators to drive UI testing, gather visual outputs, or validate app behavior.

• 3

  Session-based tracking of simulator metadata and lifecycle when orchestrating multiple concurrent simulator sessions or long-running automation tasks.

Description

This project provides a bridge between iOS simulators and the Model Context Protocol, built on top of appium-ios-simulator and the MCP TypeScript SDK. It exposes simulator lifecycle actions (boot, shutdown), app installation and launch, input interactions (taps), and screenshot capture over a stdio transport so it can be used as an MCP tool. The server supports both direct UDID-based management and a session-based layer for tracking simulator metadata, and includes file-based logging that avoids interfering with the stdio channel.
