The brief

Building and testing an iOS app from a terminal, or handing that work to an AI agent, means driving tools that were made for a person sitting in Xcode.

What I built

An MCP server and command-line tool for iOS development, so any AI agent or terminal can build, test, automate and diagnose an iOS project.

  • 109 MCP tools and 19 CLI command groups, per the project’s README.
  • A single native binary, about 8 MB stripped, with no external runtime dependencies.
  • It works with Claude Code and other MCP clients.

How it works

It’s written in Swift 6 and ships as one native binary for macOS 13 and later. It installs from my own Homebrew tap: brew tap justinthevoid/tap && brew install xcforge.

What came of it

xcforge is public and MIT-licensed, so all of it is there to read: the code on GitHub, the tools, and how they fit together. It’s the same kind of automation work I’d do for you, done in the open.

Want something like this?

I build things like this for people with an idea and not enough hours. Tell me what you’re making.

Open to a few small projects: websites, apps and automation.

If you can, mention

  • What you needa few lines is plenty
  • When you need ita date, or no rush
  • A rough budgeta range is fine

No fixed prices. Tell me the budget and I’ll say what fits.

What happens after you email

  1. You email what you need; I reply by email with questions.
  2. A written, fixed-scope proposal.
  3. I build it, and hand it over with everything you need to run it.
