# MCP Outline - Especificação Completa

**Versão:** 1.0.0
**Data:** 2026-01-31
**Autor:** Descomplicar®

---

## 1. Visão Geral

### Objectivo

MCP para acesso directo à base de dados PostgreSQL do Outline, seguindo os padrões estabelecidos pelo `mcp-desk-crm-sql-v3`.

### Arquitectura

```
┌─────────────────┐     ┌─────────────────┐     ┌─────────────────┐
│   Claude Code   │────▶│   MCP Outline   │────▶│   PostgreSQL    │
│   (Cliente)     │◀────│   (Servidor)    │◀────│   (Outline DB)  │
└─────────────────┘     └─────────────────┘     └─────────────────┘
        │                       │
        │ MCP Protocol          │ SQL Directo
        │ (stdio/SSE)           │ (pg client)
```

### Decisões Técnicas

| Aspecto | Decisão | Razão |
|---------|---------|-------|
| **Acesso** | SQL Directo (não API) | Performance, controlo total |
| **BD** | PostgreSQL 15 | Compatível com Outline |
| **Transporte** | stdio (dev), SSE (prod) | Padrão MCP |
| **Linguagem** | TypeScript | Type safety, padrão Desk |

## 8. Implementação

### Fase 1: Setup (MVP)

```bash
# 1. Criar estrutura
mkdir -p ~/mcp-servers/mcp-outline/{src/{tools,types,config,utils},tests}
cd ~/mcp-servers/mcp-outline

# 2. Inicializar
npm init -y
npm install @modelcontextprotocol/sdk pg dotenv
npm install -D typescript @types/node @types/pg tsx vitest

# 3. Configurar
cp .env.example .env
# Editar .env com credenciais

# 4. Build
npm run build

# 5. Testar
npm run dev
```

### Fase 2: Core Tools (P1)

Implementar por ordem:
1. `list_documents`, `get_document`, `search_documents`
2. `list_collections`, `get_collection`
3. `list_users`, `get_user`
4. `create_document`, `update_document`
5. `create_collection`, `update_collection`

### Fase 3: Secondary Tools (P2)

1. Comments (CRUD)
2. Memberships
3. Revisions
4. Shares
5. Events

### Fase 4: Advanced Tools (P3)

1. Templates
2. Attachments
3. OAuth
4. Import/Export

## 9. Configuração Claude Code

### ~/.claude.json

```json
{
  "mcpServers": {
    "outline": {
      "command": "node",
      "args": ["/home/ealmeida/mcp-servers/mcp-outline/dist/index.js"],
      "env": {
        "DATABASE_URL": "postgres://outline:outline_dev_2026@localhost:5432/outline"
      }
    }
  }
}
```

---

## 10. Testes

### Estrutura

```
tests/
├── setup.ts           # Configuração vitest
├── tools/
│   ├── documents.test.ts
│   ├── collections.test.ts
│   └── users.test.ts
└── integration/
    └── full-flow.test.ts
```

### Exemplo Test

```typescript
import { describe, it, expect, beforeAll } from 'vitest';
import { Pool } from 'pg';
import { listDocuments } from '../src/tools/documents';

describe('Documents Tools', () => {
  let pool: Pool;

  beforeAll(() => {
    pool = new Pool({
      connectionString: process.env.DATABASE_URL
    });
  });

  it('list_documents returns array', async () => {
    const result = await listDocuments.handler({}, pool);
    const data = JSON.parse(result.content[0].text);

    expect(Array.isArray(data.documents)).toBe(true);
    expect(data.pagination).toBeDefined();
  });
});
```

## 11. Padrões de Código (do Desk)

### Response Format

```typescript
// SEMPRE retornar neste formato
return {
  content: [{
    type: 'text',
    text: JSON.stringify(data, null, 2)
  }]
};
```

### Error Handling

```typescript
try {
  const result = await pgClient.query(sql, params);
  return {
    content: [{
      type: 'text',
      text: JSON.stringify({ success: true, data: result.rows }, null, 2)
    }]
  };
} catch (error) {
  return {
    content: [{
      type: 'text',
      text: JSON.stringify({
        success: false,
        error: error instanceof Error ? error.message : 'Unknown error'
      }, null, 2)
    }]
  };
}
```

### Naming Conventions

| Tipo | Padrão | Exemplo |
|------|--------|---------|
| Tool name | snake_case | `list_documents` |
| Function | camelCase | `listDocuments` |
| Type | PascalCase | `DocumentRow` |
| File | kebab-case | `documents.ts` |
