# 讀取監察來源覆蓋範圍

Canonical URL: https://sosoapi.ai/zh-hant/docs/mcp/listening-capabilities

`sosoapi_listening_capabilities`

先讀取實際來源、literal phrase 語法、部分樣本範圍及串流／頻率／每日用量限制；目前只支援 Hacker News，唔代表全面社交網絡搜尋或平台權限已批准。

## 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": true,
  "destructiveHint": false,
  "idempotentHint": true,
  "openWorldHint": false
}
```

`/listening-api/capabilities` — agent:research; current authorized Listening data; indexed public sample is partial and is not a verified account mention

## 輸入欄位

```json
{
  "type": "object",
  "properties": {
    "workspace_id": {
      "type": "string",
      "format": "uuid"
    }
  },
  "required": [
    "workspace_id"
  ],
  "additionalProperties": 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。
