What is iPhone-mcp CLAUDE.md?

Project instructions for blitz-ios-mcp, a tool for controlling iOS simulators and connected iPhones. They describe how to choose a device, inspect its screen, find tappable elements, and perform actions using screen coordinates.

Use them when testing iOS apps, inspecting screens, tapping controls, taking screenshots, or automating actions on simulators and physical iPhones.

They provide the required device-selection and screen-checking workflow. This helps prevent actions being sent to the wrong device or to coordinates that do not match the screen.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00355	$0.00355
Opus 5.5	$0.00142	$0.00142
Sonnet 5.5	$0.00071	$0.00071
Haiku 4.5	$0.00036	$0.00036

Security

Grade A, and why

iPhone-mcp 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.

What it actually says

blitz-ios-mcp

MCP server for controlling iOS simulators and physical iPhones.

Workflow

Call get_execution_context first to discover available devices
If target === 'ambiguous', ask the user which device to use
If target === 'device', inform the user about viewer_url so they can see the screen
If target === 'none', tell the user to boot a simulator or connect an iPhone
Pass the returned udid to all subsequent tool calls

Key Patterns

Use scan_ui before interacting — it returns interactive elements with tap coordinates
Use get_screenshot to visually verify the current screen state
Use describe_screen for the full element tree (all types, not just interactive)
All coordinates are in device screen points (not pixels)
Use device_actions for batching multiple sequential actions
Choose the smallest scan_ui region possible for speed

Physical Devices

Physical devices require WebDriverAgent (WDA) running on the device
Run npx blitz-ios-mcp --setup to install WDA and dependencies
The viewer URL shows a live screen stream in the browser
The agent cannot see the physical device screen directly — rely on scan_ui and get_screenshot

Coordinate Systems

Common iPhone screen sizes (in points):

iPhone 15/16 Pro: 393 x 852
iPhone 15/16 Pro Max: 430 x 932
iPhone SE: 375 x 667

All coordinates passed to tap/swipe should be in these point values.

Changes

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.
