xcodeproj-mcp-server: Instructions file for Claude Code

CLAUDE.md

xcodeproj-mcp-server CLAUDE.md is an instructions file for Claude Code from giginet/xcodeproj-mcp-server. It costs 1,037 tokens per session, scanned A, original, MIT.

Project instructions for an MCP server that edits Xcode project files. MCP is a standard way for software tools to expose actions to an AI assistant, and Xcode is Apple's development environment.

In plain words
What is it for?
Use it when working on the server, its Swift library or executable targets, Xcode project operations, and related tests.
Why use it?
It gives contributors a shared explanation of the server's Swift architecture, targets, dependencies, and test layout. This reduces confusion when changing project-manipulation tools.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

xcodeproj-mcp-server CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

xcodeproj-mcp-server

A Model Context Protocol (MCP) server for manipulating Xcode project files (.xcodeproj) using Swift.

Overview

This project provides an MCP server that enables interaction with Xcode projects through a standardized protocol. It leverages the tuist/xcodeproj library for project manipulation and the modelcontextprotocol/swift-sdk for MCP functionality.

Architecture

  • Language: Swift
  • Platform: macOS 13+
  • Dependencies:
    • ModelContextProtocol (MCP Swift SDK)
    • XcodeProj (Xcode project manipulation)

Package Structure

The project is organized into multiple targets for better modularity and testability:

xcodeproj-mcp-server/
├── Package.swift
├── Sources/
│   ├── XcodeProjectMCP/           # Library target
│   │   ├── XcodeProjectMCPServer.swift
│   │   ├── CreateXcodeprojTool.swift
│   │   └── [other tool implementations]
│   └── xcodeproj-mcp-server/      # Executable target
│       └── main.swift
├── Tests/
│   └── XcodeProjectMCPTests/      # Test target
│       └── CreateXcodeprojToolTests.swift
└── CLAUDE.md

Targets

  • XcodeProjectMCP (Library): Core functionality and MCP tools

    • Contains all tool implementations
    • Provides the main server class
    • Can be imported by other Swift packages

  • xcodeproj-mcp-server (Executable): Command-line interface

    • Minimal main.swift that starts the server
    • Depends on XcodeProjectMCP library

  • XcodeProjectMCPTests (Test): Unit tests

    • Tests for tool implementations
    • Integration tests for MCP functionality
    • All tests are written using swift-testing framework

Available Tools

Core Operations

  • create_xcodeproj - Create a new Xcode project with basic configuration
  • list_targets - List all targets in an Xcode project
  • list_build_configurations - List all build configurations
  • list_files - List all files in a specific target
  • get_build_settings - Get build settings for a specific target

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
