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

Casos de uso

Usos del mundo real: mattpocock/skills

Apply Matt's TS patterns to an existing project

👤 TypeScript devs upgrading code quality ⏱ ~90 min intermediate

Cuándo usarlo: Your project has anys and shrug-worthy types and you want a principled cleanup.

Requisitos previos

Skills installed — git clone https://github.com/mattpocock/skills ~/.claude/skills/mattpocock

Flujo

Scan

Use mattpocock/ts-review. Scan /src and list every any, every unsafe cast, every type hole. Group by file.✓ Copiado

→ Itemized findings, not a summary
Fix with principles

Fix the top 20, narrowest fix per case. Respect Matt's "prefer inference" rule — don't explicit-annotate what TS can infer.✓ Copiado

→ Minimal diffs, type-safety gained
Check

Run tsc --noEmit. Any regressions?✓ Copiado

→ Clean compile or precisely-scoped remaining items

Resultado: A measurably more type-safe codebase following a principled methodology.

Errores comunes

Skill applies Matt's opinions where your team disagrees (e.g. interface vs type) — Override with "skip the interface-vs-type conversion, keep existing style"

Combinar con: filesystem

Build a feature test-first, Matt's way

👤 Devs adopting a more test-forward workflow ⏱ ~60 min intermediate

Cuándo usarlo: You have a new feature to build and want to try test-first with modern TS tooling.

Flujo

Write the test

Use mattpocock/test-first. I want to add a parseInvoice function. Write the test (vitest, integration-over-unit bias) before any impl.✓ Copiado

→ Failing test with realistic fixtures
Implement

Now the minimal implementation. Type-safe, no any.✓ Copiado

→ Green test with clean types
Refactor

Apply refactor patterns from the skill — extract helpers if they earn it, no premature abstraction.✓ Copiado

→ Refactor only where the skill's criteria are met

Resultado: A test suite that tests behavior, an impl that satisfies it, and restraint on the refactor.

Errores comunes

Opinions collide with team's existing Jest setup — Ask the skill to adapt — it's opinionated but can be reoriented

Combinar con: filesystem

Combinaciones

Combínalo con otros MCPs para multiplicar por 10

mattpocock-skills-skill + filesystem

Apply to a full repo

Run ts_review over the whole /src tree and report.✓ Copiado

mattpocock-skills-skill + github

Open a PR per review

For the top 3 cleanups, create one PR each with a clear description.✓ Copiado

Herramientas

Lo que expone este MCP

Herramienta	Entradas	Cuándo llamar
ts_review	path	TS-specific audit
test_first	feature_spec	Starting a new feature
refactor_with_types	path, goal	Type-preserving refactor

Coste y límites

Lo que cuesta ejecutarlo

Cuota de API: N/A
Tokens por llamada: Review-heavy — budget for big reads on large codebases
Monetario: Free
Consejo: Scope by directory first; don't scan everything

Seguridad

Permisos, secretos, alcance

Ámbitos mínimos: filesystem-read

Almacenamiento de credenciales: None

Salida de datos: None

Resolución de problemas

Errores comunes y soluciones

Skill feels too opinionated

That's the point — override specific opinions in your prompt, or fork and edit

Recommendations conflict with team style

Share the output with the team; use it as a discussion starter, not a mandate

Doesn't know my niche library

Skills are TS-general — prepend your library's docs to the context

Alternativas

mattpocock/skills vs otros

Alternativa	Cuándo usarla	Contrapartida
Your team's linter config	You need CI-level enforcement, not interactive review	No LLM reasoning, no refactor help
Biome / ESLint with typescript-eslint	Want rules-based, deterministic	Doesn't explain its reasoning the way Matt's skills do
