Abra Claude Desktop → Settings → Developer → Edit Config. Reinicie após salvar.

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

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "claude-skill-3": {
      "command": "git",
      "args": [
        "clone",

        "~/.claude/skills/claude-skills"
      ],
      "_inferred": true
    }
  }
}

Clique no ícone MCP Servers na barra lateral do Cline, depois "Edit Configuration".

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "claude-skill-3": {
      "command": "git",

      ],
      "_inferred": true
    }
  }
}

Mesmo formato do Claude Desktop. Reinicie o Windsurf para aplicar.

~/.continue/config.json

{
  "mcpServers": [

      "name": "claude-skill-3",
      "command": "git",

        "~/.claude/skills/claude-skills"
      ]
    }
  ]
}

O Continue usa um array de objetos de servidor em vez de um map.

          "~/.claude/skills/claude-skills"
        ]
      }
    }
  }
}

Adicione em context_servers. Zed recarrega automaticamente ao salvar.

Casos de uso

Usos do mundo real: claude-skills

How to ship a Cloudflare Worker API with D1 backing

👤 Full-stack devs wanting a Worker+D1 API without boilerplate ⏱ ~45 min intermediate

Quando usar: You want a small JSON API with auth and persistence, deployed to Cloudflare.

Pré-requisitos

Skill installed — git clone https://github.com/jezweb/claude-skills ~/.claude/skills/jezweb-skills
wrangler CLI — npm i -g wrangler && wrangler login

Fluxo

Scaffold

Use the Cloudflare skill. New Worker with D1 binding, Hono router, routes: GET /todos, POST /todos, DELETE /todos/:id.✓ Copiado

→ Worker code + wrangler.toml + schema.sql
Auth

Add bearer token auth using a secret in env.✓ Copiado

→ Middleware + wrangler secret put instructions
Deploy

wrangler d1 execute + wrangler deploy steps.✓ Copiado

→ Live URL after deploy

Resultado: A deployed Worker API with D1 persistence.

Armadilhas

D1 migrations drift between envs — Use wrangler d1 migrations create + apply; don't ad-hoc exec

Upgrade a Tailwind v3 project to v4

👤 Frontend devs on v3 wanting to move to v4's new engine ⏱ ~60 min intermediate

Quando usar: You're on tailwind@3 and want to adopt v4's Oxide engine + CSS-first config.

Fluxo

Audit current config

Audit tailwind.config.{js,ts} for anything that doesn't port 1:1 to v4.✓ Copiado

→ Per-config-key migration notes
Generate v4 config

Produce the v4 equivalent: @theme in a CSS entry + package updates.✓ Copiado

→ CSS entry + package.json diff
Fix breaking utilities

Grep the codebase for removed/renamed utility classes and produce a replace map.✓ Copiado

→ Codemod suggestions

Resultado: A v4 migration PR ready for review.

Armadilhas

PostCSS pipeline conflicts with v4's native engine — Remove PostCSS plugins that v4's engine replaces

Build a lightweight RAG endpoint on Workers

👤 Devs adding AI features to a Cloudflare app ⏱ ~90 min advanced

Quando usar: You want RAG without standing up a vector DB service.

Fluxo

Set up Vectorize

Provision a Vectorize index for embeddings. Use OpenAI text-embedding-3-small.✓ Copiado

→ wrangler vectorize create + binding
Ingest script

Write a Worker route /ingest that chunks + embeds + upserts.✓ Copiado

→ Worker code with chunking heuristic
Query route

Write /query that embeds the question, retrieves top-k, and calls Claude/OpenAI with the context.✓ Copiado

→ End-to-end route

Resultado: A small but real RAG endpoint deployed on Cloudflare.

Armadilhas

Chunks too large lose recall; too small hurt context — Start 512 tokens, overlap 64; tune based on your corpus

claude-skill-3 + claude-code-owasp-skill

Security-review Worker auth and RAG endpoints

After scaffolding the Worker with auth, run OWASP review on the auth middleware.✓ Copiado

Ferramentas

O que este MCP expõe

Ferramenta	Entradas	Quando chamar	Custo
Cloudflare Worker scaffolding	-	New worker projects	Claude tokens
D1 + R2 + KV patterns	-	Persistence wiring	Claude tokens
React RSC patterns	-	RSC-era apps	Claude tokens
Tailwind v4 migration	-	v3→v4 upgrades	Claude tokens
AI integrations	-	OpenAI/Anthropic/embeddings	Claude tokens

Custo e limites

O que custa rodar

Cota de API: None at skill level
Tokens por chamada: 5-20k per task
Monetário: Free skill; Cloudflare + OpenAI/Anthropic have their own pricing
Dica: Cloudflare free tier covers small Worker APIs; watch Vectorize cost at scale.

Segurança

Permissões, segredos, alcance

Armazenamento de credenciais: No credentials at skill level. Wrangler handles CF secrets.

Saída de dados: Deploys go to Cloudflare; any AI calls go to the configured provider

Wrangler auth has full account access. Use scoped API tokens for CI, not wrangler login.

Solução de problemas

Erros comuns e correções

wrangler deploy fails on route

Route patterns require the zone to be in your CF account; check routes vs. workers.dev fallback

Verificar: wrangler deployments list

D1 migrations apply locally but not remote

Run wrangler d1 migrations apply <DB> --remote explicitly
