# Slack Lists MCP Server

An MCP (Model Context Protocol) server for managing Slack Lists. This server provides tools to create, read, update, and delete items in Slack Lists, with advanced filtering capabilities.

## Features

- ✨ Full CRUD operations for Slack List items
- 🔍 Advanced filtering with multiple operators
- 📑 Pagination support for large lists
- 🏗️ Dynamic column structure discovery
- 🎯 Type-safe operations with validation
- 🚀 Async/await support for better performance

## Installation

### Configure in Claude Desktop

Add to your Claude Desktop configuration file:

```json
{
  "mcpServers": {
    "slack-lists": {
      "command": "uvx",
      "args": ["slack-lists-mcp"],
      "env": {
        "SLACK_BOT_TOKEN": "xoxb-your-bot-token"
      }
    }
  }
}
```

## Configuration

### Environment Variables

| Variable | Description | Required | Default |
|----------|-------------|----------|---------|
| `SLACK_BOT_TOKEN` | Slack Bot User OAuth Token | ✅ | - |
| `DEFAULT_LIST_ID` | Default list ID to use when not specified in tool calls | ❌ | - |
| `LOG_LEVEL` | Logging level (DEBUG, INFO, WARNING, ERROR) | ❌ | INFO |
| `SLACK_API_TIMEOUT` | Timeout for Slack API calls (seconds) | ❌ | 30 |
| `SLACK_RETRY_COUNT` | Number of retries for failed API calls | ❌ | 3 |
| `DEBUG_MODE` | Enable debug mode | ❌ | false |

### Setting up Slack Bot

1. Create a Slack App at [api.slack.com](https://api.slack.com/apps)
2. Add the following OAuth scopes to your Bot Token:
   - `lists:read` - Read list items
   - `lists:write` - Create and update list items
3. Install the app to your workspace
4. Copy the Bot User OAuth Token (starts with `xoxb-`)

### Using Default List ID

You can set a default list ID using the `DEFAULT_LIST_ID` environment variable. This allows you to omit the `list_id` parameter from tool calls when working with a specific list.

**Example configuration:**
```json
{
  "mcpServers": {
    "slack-lists": {
      "command": "uvx",
      "args": ["slack-lists-mcp"],
      "env": {
        "SLACK_BOT_TOKEN": "xoxb-your-bot-token",
        "DEFAULT_LIST_ID": "F1234567890"
      }
    }
  }
}
```

With this configuration, you can call tools without specifying `list_id`:
- `add_list_item` with just `initial_fields`
- `list_items` with just `limit` and `filters`
- `get_list_structure` with no parameters

## Available Tools

### 1. `get_list_structure`
Get the column structure of a Slack List.

**Parameters:**
- `list_id` (optional): The ID of the list (uses DEFAULT_LIST_ID env var if not provided)

## ベストプラクティス

### `add_list_item`の正しい使い方

`add_list_item`を呼び出す際は、**必ず`initial_fields`パラメータを含める**必要があります。エラーを避けるために、以下のポイントに注意してください：

#### ✅ 推奨される使い方

1. **事前に`get_list_structure`を呼び出す**
   - リストの列構造を理解してから、アイテムを追加します
   - 正しい`column_id`を取得できます

2. **`initial_fields`は必須パラメータ**
   - 必ず配列形式で渡します: `[{...}, {...}]`
   - 各フィールドには`column_id`と値のフィールドが必要です

3. **簡潔な形式を使用する**
   - `text`フィールド: 文字列をそのまま渡す（自動的にrich_textに変換されます）
   - `user`フィールド: 単一のユーザーIDまたは配列
   - `select`フィールド: 単一の選択肢IDまたは配列

#### 正しい例

```python
# 1. リスト構造を取得
structure = await get_list_structure()

# 2. column_idを確認してアイテムを追加
await add_list_item(
    initial_fields=[
        {"column_id": "Col08N4PWM7PZ", "text": "自立型AIエージェントの導入"},
        {"column_id": "Col08NWP011DF", "user": ["U09ES6QB8BV"]}
    ]
)
```

#### ❌ よくあるエラー

1. **`initial_fields`パラメータが欠けている**
   ```python
   # エラー: 'initial_fields' is a required property
   await add_list_item(list_id="F123")
   ```

   **修正方法**: 必ず`initial_fields`を含める
   ```python
   await add_list_item(
       list_id="F123",
       initial_fields=[{"column_id": "Col123", "text": "タスク名"}]
   )
   ```

2. **空の配列を渡す**
   ```python
   # エラー: At least one field must be provided
   await add_list_item(initial_fields=[])
   ```

   **修正方法**: 少なくとも1つのフィールドを含める

3. **`column_id`が欠けている**
   ```python
   # エラー: Each field must have a 'column_id'
   await add_list_item(initial_fields=[{"text": "タスク名"}])
   ```

   **修正方法**: 各フィールドに`column_id`を含める

### トラブルシューティング

#### エラー: "Input validation error: 'initial_fields' is a required property"

**原因**: `initial_fields`パラメータが正しく渡されていません。

**解決方法**:
1. パラメータ名が正しいことを確認（`initial_fields`、スペルに注意）
2. 配列形式で渡していることを確認
3. JSONの構文が正しいことを確認

#### エラー: "Each field must have a 'column_id'"

**原因**: フィールドに`column_id`が含まれていません。

**解決方法**:
1. `get_list_structure`を呼び出して正しい`column_id`を確認
2. 各フィールドに`column_id`を追加

#### エラー: "At least one field must be provided"

**原因**: `initial_fields`が空の配列です。

**解決方法**:
少なくとも1つのフィールドを含める（通常は名前/タイトルフィールド）
