A Model Context Protocol (MCP) server for interacting with iOS simulators. This server allows you to interact with iOS simulators by getting information about them, controlling UI interactions, and inspecting UI elements.
Security Notice: Command injection vulnerabilities present in versions < 1.3.3 have been fixed. Please update to v1.3.3 or later. See SECURITY.md for details.

Questions
What is the iOS Simulator MCP server?
MCP server for interacting with the iOS simulator
What tools does iOS Simulator expose?
17 in total: 14 read-only, 2 that write, and 1 that can delete or overwrite (terminate_app). 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: 1 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 ios-simulator-mcp at 2.1.0.
How current is this page?
The grade is for one exact copy of the source (b7370c02f725), read on 2026-09-23. The repository is watched and re-audited when it changes.
