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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01476 | $0.01476 |
| Opus 5.5 | $0.00590 | $0.00590 |
| Sonnet 5.5 | $0.00295 | $0.00295 |
| Haiku 4.5 | $0.00148 | $0.00148 |
Grade A, and why
ios-mcp-code-quality-server copilot-instructions.md scanned grade A with 1 finding 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 1mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
2. Test MCP endpoint: `curl -s http://localhost:3000/` How it starts

iOS MCP Code Quality Server
ALWAYS FOLLOW THESE INSTRUCTIONS FIRST. Only use additional search and context gathering if the information here is incomplete or found to be in error.
This is a Node.js TypeScript MCP (Model Context Protocol) server that provides iOS code quality analysis tools including test running and SwiftLint integration. The server exposes test and lint tools via the MCP protocol for integration with AI coding agents.
Working Effectively
Bootstrap and Build (Required First Steps)
npm install # Takes ~2 seconds
tsc -p tsconfig.build.json --noEmit false # Takes ~2 seconds
Start the MCP Server
npm start
# OR run directly:
node dist/index.js
Server starts on port 3000 and provides MCP protocol endpoints at http://localhost:3000/.
Run Tests
npm test # Takes ~1 second. All 19 tests should pass.
Linting (Currently Broken)
npm run lint # FAILS: ESLint config missing
Do NOT try to fix the linting - it fails due to missing ESLint configuration file.
iOS Development Dependencies (CRITICAL LIMITATIONS)
This server is designed to work with iOS development tools that are ONLY available on macOS:
Required but NOT Available in Linux/CI Environments:
- Xcode Command Line Tools:
xcodebuild,xcrun,xcresulttool - SwiftLint: For Swift code linting and auto-correction
- macOS: iOS development tools only work on macOS
What Works Without iOS Tools:
- Build and start the MCP server
- Run the test suite (uses mocked data)
- Basic server functionality
What Does NOT Work Without iOS Tools:
- Actual iOS project testing via
xcodebuild test - SwiftLint code analysis
- Real iOS code quality analysis
Timing and Cancellation Warnings
- Build: TypeScript compilation takes ~2 seconds - no special timeout needed
- Tests: Complete test suite runs in ~1 second - no special timeout needed
- Install: Dependencies install in ~2 seconds - no special timeout needed
- Server Start: Server starts immediately after build completes
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.
