# Development with ts-node
npm run dev

# Run tests
npm test
```

## Configuration

Add to `~/.claude.json` under `mcpServers`:

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

## Environment

Required in `.env`:
```
DATABASE_URL=postgres://user:password@host:port/outline
```

## Key Patterns

### Tool Response Format

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

### Naming Conventions

| Type | Convention | Example |
|------|------------|---------|
| Tool name | snake_case with prefix | `outline_list_documents` |
| Function | camelCase | `listDocuments` |
| Type | PascalCase | `DocumentRow` |
| File | kebab-case | `documents.ts` |

## Database

**PostgreSQL 15** - Direct SQL access (not Outline API)

Key tables: `documents`, `collections`, `users`, `groups`, `comments`, `revisions`, `shares`, `attachments`, `events`, `stars`, `pins`, `views`, `file_operations`, `oauth_clients`

Soft deletes: Most entities use `deletedAt` column, not hard deletes.

See `SPEC-MCP-OUTLINE.md` for complete database schema.
