What it does
An MCP server that lets coding agents build, test, and run iOS apps on a remote Mac fleet without requiring a local Mac or Xcode installation. It exposes XcodeBuildMCP-compatible tool names, so workflows written for local Mac setups transfer directly to remote execution.
- Build and test an iOS or React Native app from a Linux machine or CI container by running build_sim or test_sim against a remote Mac.
- Launch an iOS app in a remote simulator and get a browser URL to view the live session using build_run_sim.
- Validate that a project's schemes resolve and Swift files parse correctly before committing, using check_project with no API key required.
Tools this server exposes
| Tool | Does |
|---|---|
| discover_projs | Find .xcworkspace, .xcodeproj, or Package.swift files in the local workspace. |
| list_schemes | List shared schemes for a given project or workspace, resolved locally. |
| list_sims | Return available simulators, runtimes, and Xcode versions on the remote fleet. |
| check_project | Validate that schemes resolve, Swift files parse, and plists are valid on a remote Mac — no API key required. |
| build_sim | Compile the project for the iOS Simulator on a remote Mac and return file/line/column errors. |
| test_sim | Build and run XCTest or Swift Testing tests on a remote Mac, returning per-test results. |
| build_run_sim | Build, install, and launch the app in a remote simulator and return a browser URL to the live session. |
| stop_app_sim | End an active live simulator session. |
| archive_app | Produce an unsigned .xcarchive in Release configuration on a remote Mac. |
| job_status | Retrieve status, diagnostics, test results, and log tail for any submitted job. |
| doctor | Check API key validity, API reachability, and fleet capabilities. |
Before you enable it
An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
