Ios SimulatorSAFE
Model Context Protocol (MCP) implementation for iOS simulators
Overview
From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.
[](https://smithery.ai/server/@atom2ueki/mcp-server-ios-simulator)
A server that implements the Model Context Protocol (MCP) for iOS simulators, built on top of appium-ios-simulator and utilizing the MCP TypeScript SDK.
📋 Overview
This project provides a bridge between iOS simulators and the Model Context Protocol, allowing for standardized communication with iOS simulator instances. It enables programmatic control of iOS simulators while leveraging the MCP protocol for consistent interfaces across different environments. The server utilizes stdio as its transport mechanism, making it ideal for integration with Claude Desktop and other MCP-compatible clients.

🏗️ Architecture
The server consists of three main components:
- 🔄 Simulator Management Layer - Handles iOS simulator lifecycle and interactions
- 🔌 MCP Protocol Implementation - Implements the Model Context Protocol using the TypeScript SDK with stdio transport
- 📊 Logger Component - Provides file-based logging without interfering with the stdio transport

Questions
What is the Ios Simulator MCP server?
Model Context Protocol (MCP) implementation for iOS simulators
What tools does Ios Simulator expose?
12 in total: 8 read-only, 2 that write, and 2 that can delete or overwrite (terminate-app, terminate-simulator-session). Every one is listed on this page with its risk.
Is Ios Simulator safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B. Separately from the audit: 2 of its tools can destroy data, so scope the token you give it to what you actually need.
What credentials does Ios Simulator need?
No credential environment variables were found in its source, so it appears to need none.
How does Ios Simulator run?
It speaks stdio, so it runs as a local process your client starts. It is published on npm as mcp-server-ios-simulator at 0.1.0.
How current is this page?
The grade is for one exact copy of the source (5bf1ba5e8605), read on 2026-10-08. The repository is watched and re-audited when it changes.
