Cursor usa el mismo esquema mcpServers que Claude Desktop. La configuración del proyecto prevalece sobre la global.

Casos de uso

Usos del mundo real: skills

Refactor a legacy module using the Clean Code + Refactoring patterns

👤 Senior developers tackling legacy code ⏱ ~120 min advanced

Cuándo usarlo: You're about to touch a 500-line god-class and want principled guidance.

Flujo

Assess with Clean Code lens

Use the Clean Code skill. Review this file — what SOLID violations are present?✓ Copiado

→ Concrete violations named after principles, not vibes
Plan with Refactoring patterns

Use the Refactoring Patterns skill. Plan the refactor using Extract Class and Replace Conditional with Polymorphism.✓ Copiado

→ Named Fowler refactorings with stepwise plan
Execute incrementally

Apply the first step; run tests; repeat.✓ Copiado

→ Small safe steps, not one giant rewrite

Resultado: A refactor defensible in code review with explicit principles.

Errores comunes

Refactor without tests = risk — Skill insists on characterization tests first

Combinar con: claude-skill-2

Run Mom Test-style customer interviews

👤 Founders validating a product idea ⏱ ~45 min intermediate

Cuándo usarlo: Before writing any code, you need to pressure-test the problem.

Flujo

Plan the interview

Use the Mom Test skill. I want to validate [idea]. Help me draft questions that avoid bias.✓ Copiado

→ Questions focused on past behavior, not hypothetical future
Debrief after calls

Here are notes from 5 calls. Apply the Mom Test frame — what's signal vs compliment?✓ Copiado

→ Honest separation of validated evidence from polite agreement

Resultado: Interview notes you can actually make a decision on.

Errores comunes

Customer says 'I'd buy that' — skill flags this as worthless without behavior evidence — Trust the frame; push for past behavior

Combinar con: product-manager-skill

Design a system using DDIA + System Design skills

👤 Senior engineers and architects ⏱ ~90 min advanced

Cuándo usarlo: You're whiteboarding a new service and want depth, not hand-waving.

Flujo

State constraints

Use the DDIA and System Design skills. Design a real-time leaderboard for 5M users. Discuss reliability, scalability, maintainability.✓ Copiado

→ Tradeoffs from DDIA vocabulary (replication, partitioning, consistency)
Pressure-test

Apply the Release It! skill — what failure modes should I anticipate?✓ Copiado

→ Stability patterns (circuit breaker, bulkhead, timeout) named explicitly

Resultado: A design doc that a staff engineer would take seriously.

Errores comunes

Skills can over-index on book vocabulary — Insist on concrete numbers — latency targets, QPS, data sizes

Combinaciones

Combínalo con otros MCPs para multiplicar por 10

skills-skill + product-manager-skill

Books-based discovery + PM deliverable templates

Use Mom Test skill for the interview plan, then the product-manager-skill to turn findings into a PRD.✓ Copiado

skills-skill + claude-skill-2

Clean Code / Refactoring skill for principles + full-stack skill for implementation

Refactor the auth module guided by the Clean Code skill; implement with the NestJS skill from claude-skill-2.✓ Copiado

Herramientas

Lo que expone este MCP

Herramienta	Entradas	Cuándo llamar
Code Craftsmanship skills (14)	code to review/design	Code quality, architecture, design work
UX Design skills (8)	design problem	UI/UX decisions
Product Strategy skills (4)	product question	Discovery, framing
Marketing & CRO skills (4)	marketing question	Messaging, landing pages
Strategy & Growth skills (4)	strategy question	Market/strategy decisions

Coste y límites

Lo que cuesta ejecutarlo

Cuota de API: None
Tokens por llamada: 2-6k per skill
Monetario: Free — skill is local
Consejo: Pick one book-skill per task; stacking too many blurs recommendations.

Seguridad

Permisos, secretos, alcance

Almacenamiento de credenciales: No credentials — skill is prompts

Salida de datos: None

Resolución de problemas

Errores comunes y soluciones

Skill quotes principles but doesn't apply them

Force application: 'apply this principle to THIS line of my code, not in general'.

Not obvious which skill to invoke

The README maps problems to skills — start there.

Alternativas

skills vs otros

Alternativa	Cuándo usarla	Contrapartida
Reading the books directly	You want depth and have time	More depth, no interactive application
product-manager-skill / claude-skill-2	You want deliverable templates or framework code, not book wisdom	Different modality
