# 查詢素材

Canonical URL: https://sosoapi.ai/zh-hant/docs/mcp/query-assets

`sosoapi_query_assets`

明確傳 workspace_id，按 asset_type、source 或 tag 查素材；回傳分頁及總數，limit 最大 100，配合 offset。

## Profiles 及連接方式

Profiles: core, full

Transports: stdio, http

Profile 只影響工具可見性，唔會授權。HTTP 冇本機檔案上傳。SOSOAPI_OUTPUT_SCHEMAS=1 會宣告輸出 schema；兩種模式都會回傳 structured results。

## 權限及改動

MCP annotations 只係發現提示，唔係存取控制保證；仍然有實際登入、角色、資源及能力檢查。

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

## 結構化輸出

此 schema 描述成功工具結果嘅 structuredContent。MCP envelope 亦包括 content，失敗可能設定 isError；唔好將文字收據或接受請求當成平台終態。權限及重試規則見對應 API 操作。
