# 準備私人訊息回覆

Canonical URL: https://sosoapi.ai/zh-hant/docs/mcp/dm-actions-prepare

`sosoapi_dm_actions_prepare`

準備確切且不可變更的私人訊息審閱內容，並取得短效單次 token。系統會重新核對目前帳戶、授權及回覆時限。

## Profiles 及連接方式

Profiles: full

Transports: stdio, http

Profile 只影響工具可見性，不會授予權限。HTTP 不提供本機檔案上傳。SOSOAPI_OUTPUT_SCHEMAS=1 會宣告輸出 schema；兩種模式均會回傳 structured results。

## 權限及改動

MCP annotations 只提供工具發現提示，並非存取控制保證；實際呼叫仍須通過登入、角色、資源及能力檢查。

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

## 結構化輸出

此 schema 描述成功工具結果的 structuredContent。MCP envelope 亦包括 content，失敗時可能設定 isError；請勿將文字收據或已接受的請求視為平台終態。權限及重試規則請參閱對應的 API 操作。

## 工具呼叫範例

以下虛構值已按 contract 驗證，並非真實帳戶 ID、憑證或發佈紀錄。請以已授權範圍回傳的 ID、已準備完成的素材及已審核排程取代，並在寫入前核對平台資格。此頁不會呼叫 API。

```json
{
  "name": "sosoapi_dm_actions_prepare",
  "arguments": {
    "workspace_id": "11111111-1111-4111-8111-111111111111",
