# list_attachments

> List task attachments with Mill MCP.

List completed attachments for a task, newest first. Use `nextCursor` to continue.

## Workflow

```mermaid theme={"system"}
flowchart LR
  step0["Resolve the task UUID"] --> step1
  step1["List completed files"] --> step2
  step2["Continue with nextCursor"]
```

## Access and behavior

A Read-only, Write or Administrator OAuth grant can call this tool within the user’s current team role. Tools are listed and callable only when the current grant and role permit them.

Pending uploads are not listed. Metadata never contains permanent public URLs.

## Arguments

| Argument | Required | Type or meaning |
| - | - | - |
| `taskId` | Yes | Task UUID, not its human identifier such as ENG-1. |
| `limit` | No | integer |
| `cursor` | No | Opaque nextCursor from the preceding response with identical filters. |

## Example call

The client initializes the MCP connection before sending this JSON-RPC call. Example records are fictional.

```json theme={"system"}
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "list_attachments",
    "arguments": {
      "taskId": "22222222-2222-4222-8222-222222222222",
      "limit": 50
    }
  }
}
```

## Example result

Mill returns this object in `structuredContent` and normally a JSON text content block (large responses may shorten the text block). A tool failure sets `isError`; never treat an error as a completed mutation.

```json theme={"system"}
{
  "items": [
    {
      "id": "44444444-4444-4444-8444-444444444444",
      "taskId": "22222222-2222-4222-8222-222222222222",
      "fileName": "restore-report.pdf",
      "contentType": "application/pdf",
      "sizeBytes": 2048,
      "createdBy": "66666666-6666-4666-8666-666666666666",
      "createdAt": "2027-01-18T09:30:00.000Z"
    }
  ],
  "hasMore": false,
  "nextCursor": null
}
```
