# complete_upload

**Finish an upload**

Verify uploaded bytes against their declared size, type and checksum, and return the upload ready to bind to a generation.

## Scope

- `generation.write` — Makes, edits, imports, shares and deletes media in the account.

## Behaviour

- **Writes**: Creates or changes items in the caller's own account.
- **Adds or updates**: Adds or updates; nothing the caller already has is deleted or overwritten.
- **Stays in the account**: Stays inside the caller's private Kuro account: any media provider it calls acts on Kuro's account, and the result is visible to no one else.

## Inputs

| Name | Type | Required | Details |
| --- | --- | --- | --- |
| `upload_id` | string | yes | uuid |
| `checksum_sha256` | string | no | matches ^[0-9a-f]{64}$ |
| `width` | integer | no | > 0 |
| `height` | integer | no | > 0 |

## Example call

A `tools/call` request with the required arguments only, each a placeholder read off the schema. Replace them before sending.

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "complete_upload",
    "arguments": {
      "upload_id": "00000000-0000-4000-8000-000000000000"
    }
  }
}
```

## Input schema

As the server sends it in `tools/list`:

```json
{
  "type": "object",
  "properties": {
    "upload_id": {
      "type": "string",
      "format": "uuid"
    },
    "checksum_sha256": {
      "type": "string",
      "pattern": "^[0-9a-f]{64}$"
    },
    "width": {
      "type": "integer",
      "exclusiveMinimum": 0
    },
    "height": {
      "type": "integer",
      "exclusiveMinimum": 0
    }
  },
  "required": [
    "upload_id"
  ],
  "additionalProperties": false
}
```

## About Kuro

Kuro is an AI picture studio: prompt-driven images, clips, voice-overs and music, and storyboard-backed films with consistent characters across every scene.

Agents connect over MCP and can generate directly:

```
claude mcp add kuro https://api.meetkuro.com/mcp --transport http
```

The app is at https://app.meetkuro.com and requires an account.

Each guide, model page, comparison and free tool page on this site (not a tool's variants, and not the index pages) has a Markdown twin at its own URL plus `.md`, and so do /benchmarks/, the English /agents/ page (as /agents.md) and the MCP tool reference.
