### Available Tools

#### downloadTaskAttachment

Download a specific attachment from a JIRA task by filename.

**Parameters:**
- `taskId` (string, required): JIRA task ID (e.g., PROJECT-123)
- `filename` (string, required): Exact filename of the attachment to download

**Response:**
Returns base64 encoded binary data with metadata including:
- `filename`: The name of the downloaded file
- `mimeType`: The MIME type of the file
- `size`: The file size in bytes
- `content`: Base64 encoded file content

**Example Usage:**
```json
