Cursor usa o mesmo esquema mcpServers que o Claude Desktop. Config de projeto vence a global.

Casos de uso

Usos do mundo real: ios-simulator-skill

Build, run, and screenshot the current flow

👤 iOS devs using Claude Code to iterate ⏱ ~5 min beginner

Quando usar: You changed a view and want to see it live without leaving the chat.

Pré-requisitos

Xcode + simulator installed — Standard macOS iOS dev setup

Fluxo

Ask Claude to build and run

Use ios-simulator-skill. Build MyApp scheme for iPhone 16, launch, navigate to Settings, screenshot.✓ Copiado

→ Compact build summary, then the screenshot
Iterate

I tweaked the padding — rebuild and re-screenshot.✓ Copiado

→ Fast turn with minimal token overhead

Resultado: Tight build-iterate-view loop in Claude Code.

Armadilhas

Scheme name typo causes unclear error — Skill returns a compact list of available schemes on mismatch

Combine com: filesystem

Drive a scripted UI flow for smoke testing

👤 iOS devs and QA ⏱ ~15 min intermediate

Quando usar: You want to verify a critical flow without writing full XCUITest scaffolding.

Fluxo

Describe the flow

Launch the app, tap 'Sign in', enter creds, tap the first row in the list, screenshot.✓ Copiado

→ Claude uses accessibility labels to drive each step
Check WCAG compliance

Now run the accessibility audit on the current screen.✓ Copiado

→ WCAG findings with fix suggestions

Resultado: A working smoke flow plus an a11y pass.

Armadilhas

Flow breaks when a label changes — Labels are more stable than coordinates, but still review after big UI refactors

Tail logs while reproducing a bug

👤 iOS devs chasing a flaky issue ⏱ ~10 min intermediate

Quando usar: A bug only repros in the simulator and you want the relevant logs.

Fluxo

Reproduce with filtered logs

Launch the app, tap through the crashing flow, tail logs filtered to error+warning.✓ Copiado

→ Claude returns a trimmed log bundle and highlights the likely cause

Resultado: A targeted log excerpt and a hypothesis for the bug.

Armadilhas

Logs too noisy if severity filter not set — Default to error+warning; raise to info only when debugging

Combinações

Combine com outros MCPs para 10× de alavancagem

ios-simulator-skill + filesystem

Skill runs the build; filesystem reads/writes the sources

Edit SettingsView.swift, then build and screenshot.✓ Copiado

ios-simulator-skill + github

Reproduce an issue from a GitHub bug report in the simulator

Read issue #42, reproduce the steps in the simulator, attach screenshot to a comment.✓ Copiado

Ferramentas

O que este MCP expõe

Ferramenta	Entradas	Quando chamar
xcodebuild wrapper	scheme, destination	Any build request
Simulator driver (accessibility APIs)	element label/role + action	UI automation in the simulator
Screenshot capture	none (current screen)	Visual verification
Log tailing	severity filter, duration	Debugging runtime issues
Device lifecycle	boot/shutdown/create/reset	Fresh simulator state needed
Accessibility audit	current screen	A11y review

Custo e limites

O que custa rodar

Cota de API: None
Tokens por chamada: Very low — compact build summaries + compressed screenshots are the main design goal
Monetário: Free — skill is local
Dica: Keep screenshots at default compression; full-res screens eat context fast.

Segurança

Permissões, segredos, alcance

Armazenamento de credenciais: No credentials in the skill. App-side secrets stay in your build config.

Saída de dados: None — everything runs on local simulators

Simulators have access to your keychain if you've configured it — be careful with credentials during automation.

Solução de problemas

Erros comuns e correções

'No such scheme'

Skill lists available schemes on mismatch; pick the exact name.

Verificar: xcodebuild -list -project MyApp.xcodeproj

Accessibility label not found

Add accessibilityIdentifier to the SwiftUI view — it's more stable than the visible label.

Simulator stuck booting

Use the device-lifecycle reset command; then re-boot.

Verificar: xcrun simctl list

Alternativas

ios-simulator-skill vs. outros

Alternativa	Quando usar	Troca
Direct xcodebuild + simctl	You don't mind the token bloat from raw output	No abstraction; verbose
XcodeBuildMCP	You prefer an MCP server with structured tools	MCP route; this skill is local scripts
