# 連結專案素材

Canonical URL: https://sosoapi.ai/zh-hant/docs/mcp/link-project-asset

`sosoapi_link_project_asset`

將現有素材以 identity、source 或 reference 關係連結到專案。需要 editor 角色及 idempotency_key。

## Profiles 及連接方式

Profiles: 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": false,
  "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。

## 工具呼叫範例

以下虛構值已按 contract 驗證，唔係真實帳戶 ID、憑證或發佈紀錄。請用已授權範圍回傳嘅 ID、已準備好嘅素材及已審核排程取代，寫入前核對平台資格。此頁唔會呼叫 API。

```json
{
  "name": "sosoapi_link_project_asset",
  "arguments": {
    "project_id": "11111111-1111-4111-8111-111111111111",
    "asset_id": 1,
    "relationship": "identity",
    "idempotency_key": "example-intent-0001"
  }
}
```
