🚀 XCode CLI MCP is a convenient wrapper for Xcode CLI tools. It shortens long outputs by summarizing them, helping reduce token usage when interacting with language models. It keeps your workflow smooth while you focus on code, builds, and diagnostics.

Why XC-MCP

  • You work with Xcode CLI tools daily. The outputs can be verbose and noisy.
  • You want fewer tokens when you feed logs and commands into an LLM.
  • You need a reliable wrapper that can summarize, filter, and structure CLI results.
  • You want a simple tool that stays out of your way and focuses on your code.

Core ideas and concepts

  • Convenience wrapper: It sits on top of the standard Xcode command line tools, adding a friendly layer that surfaces essential information.
  • Output summarization: Long CLI outputs get converted into concise, context-rich summaries.
  • Model-context friendly: The wrapper prepares compact prompts that preserve meaning and intent for LLMs.
  • Extensible: The architecture supports multiple “contexts” and adapters, enabling easy integration with different tooling chains.
  • Local-first by default: Summaries and context data stay on your machine unless you opt-in to share.
