# 列出孤立素材

标准 URL： https://sosoapi.ai/zh-hans/docs/mcp/list-orphan-assets

`sosoapi_list_orphan_assets`

列出工作区中没有任何素材记录指向的已存储对象（存储清理），按延续令牌分页。仅限工作区所有者。

## 配置与传输方式

配置：full

传输方式：stdio、http

选择 core 或 full 以控制客户端显示的工具；这不会变更权限。本地文件上传需要 stdio，无法通过 HTTP 使用。设置 SOSOAPI_OUTPUT_SCHEMAS=1 可在探索结果加入输出schema。无论是否启用此设置，工具皆会返回结构化结果。

## 权限与副作用

注解帮助客户端描述工具。每次调用仍会检查用户身份验证、角色、资源访问和能力授权。

```json
{
  "readOnlyHint": true,
  "destructiveHint": false,
  "idempotentHint": true,
  "openWorldHint": false
}
```

`/assets-api/orphans/list` — agent:operate；synchronous_http_response

## 输入字段

```json
{
  "type": "object",
  "properties": {
    "workspace_id": {
      "type": "string",
      "format": "uuid"
    },
    "object_continuation_token": {
      "type": "string",
      "minLength": 1,
      "maxLength": 2048
    },
    "continuation_token": {
      "type": "string",
      "minLength": 1,
      "maxLength": 2048
    },
    "limit": {

      "minimum": 1,
      "maximum": 200
    }
  },
  "required": [
    "workspace_id"
  ]
}
```

## 结构化输出

此 schema 描述成功工具结果中的 structuredContent。MCP 响应也包含 content，并可能在调用失败时设置 isError。对于发布，请读取帖子的最终结果，不要把获接受的请求或文字响应当作确认。链接的 API 操作说明了权限和重试规则。
