# 解除專案素材連結

標準 URL： https://sosoapi.ai/zh-tw/docs/mcp/unlink-project-asset

`sosoapi_unlink_project_asset`

移除素材與專案的連結；保留素材本身。需要 idempotency_key。

## 設定與傳輸方式

設定：full

傳輸方式：stdio、http

選擇 core 或 full 以控制用戶端顯示的工具；這不會變更權限。本機檔案上傳需要 stdio，無法透過 HTTP 使用。設定 SOSOAPI_OUTPUT_SCHEMAS=1 可在探索結果加入輸出結構描述。無論是否啟用此設定，工具皆會回傳結構化結果。

## 權限與副作用

註解幫助用戶端描述工具。每次呼叫仍會檢查使用者身分驗證、角色、資源存取和能力授權。

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

## 結構化輸出

此 schema 描述成功工具結果中的 structuredContent。MCP 回應也包含 content，並可能在呼叫失敗時設定 isError。對於發布，請讀取貼文的最終結果，不要把已接受的請求或文字回應當作確認。連結的 API 操作說明了權限和重試規則。
