# 取消公開來源擷取 Canonical URL: https://sosoapi.ai/zh-hant/docs/mcp/research-evidence-cancel `sosoapi_research_evidence_cancel` 以原 mutation_id 取消來源讀取，首次回應前亦可提出取消。早到的取消會阻止之後開始讀取；已完成結果與取消競爭以持久狀態為準。 ## 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": true, "idempotentHint": true, "openWorldHint": true } ``` `/research-api/evidence/cancel` —
