概覽

AI 產生的概覽

Ephemeral 在隔離沙箱中執行 AI 代理任務,支援成本上限、已儲存工作流程、排程與受限連線。

可以做什麼
  • 建立、查詢、等待、列出與取消代理執行,每次執行都有成本上限與逾時
  • 讀取執行狀態、輸出、錯誤以及最終或暫定費用
  • 列出、檢視、儲存與刪除可重複使用的工作流程,包含其輸入與輸出結構
  • 列出模型(上下文長度與 token 價格)以及組織已儲存的受限連線
  • 列出、檢視、建立、修改、暫停、預覽、立即執行與刪除 cron 排程
  • 依 id、名稱、大小與類型列出組織已儲存的檔案
適用情境
適合讓助理把任務交給有花費上限的沙箱代理執行、存成可重複使用的工作流程,或依 cron 排程觸發。也方便在同一段對話中查看執行費用與結果。
執行需求
遠端 streamable HTTP 端點 app.ephemer.al,無需本機套件。未使用 OAuth 登入的用戶端須在 Authorization 標頭以 bearer 權杖送出 Ephemeral API 金鑰,金鑰在儀表板 Keys 中建立(代理請用成員金鑰)。修改排程需要管理員金鑰。
安裝前請注意
執行會向所屬組織計費,取消不會退還已完成工作的費用;計費結算前費用為暫定值。排程工具需要管理員金鑰,且會啟動週期性計費執行。儲存或刪除工作流程與排程會變更組織共用狀態,刪除工作流程會使引用它的排程無法啟動。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Ephemeral,將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Web executable,透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。

交給代理程式安裝

把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式,或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南,先向你展示發布者、端點和登入方式,經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。

閱讀 https://sourceweft.com/mcp/al.ephemer%2Fephemeral/install.md,並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前,先告訴我它的發布者、端點和登入方式,等我確認。不要把 API 金鑰寫進命令或我會提交的檔案;問我金鑰應從哪裡取得。

工具

create_run

Create a run

Start an AI agent run in an isolated sandbox and return the run (status queued) at once. Give a prompt, or the name of a saved workflow. Poll with get_run or block with wait_for_run for the result. Every run has a cost cap (max_cost_micros) and a timeout, and is billed to the organization of the API key. Connections must already be saved in the organization; reference them by name. Use idempotency_key to make a retry safe. A run's cost_micros is provisional (usually above the final cost) until cost_final is true; see get_run. On the hosted service a run costs a run fee once its worker starts, compute per second, model calls at the provider's price plus a percentage, and web requests and searches at flat prices; `GET /v1/me` reports the rates.

輸入參數webfilesinputmodelshellpromptworkflowconnectionsdescriptioninput_schemaoutput_schemaidempotency_key另有 3 個

get_run

Get a run

Read a run: status, output, error, cost and billing_pending. COST: while billing_pending is true (or the run is still going), cost_micros is PROVISIONAL and usually higher than the final cost; the result then has cost_final:false and a cost_note. Quote a cost only when cost_final is true (the run is finished and billing_pending is false); otherwise call get_run again in a few seconds. For a zero-data-retention run the first read of a finished run returns the output and then deletes it. On the hosted service a run costs a run fee once its worker starts, compute per second, model calls at the provider's price plus a percentage, and web requests and searches at flat prices; `GET /v1/me` reports the rates.

輸入參數id必填

wait_for_run

Wait for a run

Wait until a run finishes (succeeded, failed, cancelled, interrupted or timed_out) or the wait ends, then return the run. After the run finishes it keeps waiting, within the same time, until billing has settled (billing_pending false, normally a few seconds to about 20), so the cost is final. Waits at most 60 seconds; if the run is still going, the returned status says so and you can call it again. COST: if the result has cost_final:false, cost_micros is PROVISIONAL and usually higher than the final cost; do not quote it, call get_run again shortly. Quote the cost only when cost_final is true.

輸入參數id必填timeout_seconds

list_runs

List runs

List the organization's runs, newest first, with a cursor for the next page. Each run has cost_final: when false, cost_micros is provisional (usually above the final cost) and billing is still settling.

輸入參數limitcursorstatus

cancel_run

Cancel a run

Cancel a run that has not finished. Work already done is billed. Cancelling a finished run changes nothing.

輸入參數id必填

list_workflows

List workflows

List the organization's saved workflows (reusable run definitions). Each entry has the workflow's name and, when set, its description, input_schema (the shape of the input create_run expects) and output_schema (the shape of the JSON it returns), so you can call a workflow without reading its prompt. Run one with create_run and its name.

無需輸入參數。

get_workflow

Get a workflow

Read a saved workflow's definition: description, prompt, model, files, connections, limits and its input_schema and output_schema. Credentials are never included.

輸入參數name必填

list_models

List models

Find models. Returns a compact list (id, name, context_length, input and output USD per million tokens, zero_data_retention where known), the total count and the default model. There are hundreds of models, so filter with query (case-insensitive part of the id or name, e.g. "claude", "gpt") and read the hint when the list is truncated (default 25, at most 100). Pass model for one model's full details. Use an id from it as create_run's model.

輸入參數idlimitmodelqueryzero_data_retention

list_connections

List connections

The organization's saved connections that a run may use, with type, allowed methods and tools. No URLs or secrets are returned. Reference one in create_run by name.

無需輸入參數。

save_workflow

Save a workflow

Create a workflow, or replace the one with this name (saving the same definition again changes nothing more). A workflow is a reusable run definition: start it with create_run and its name, or on a timetable with create_schedule. Connections must already be saved in the organization; reference them by name, never with a URL or a credential. Read the current definition with get_workflow first when you change part of it, because saving replaces the whole definition. Give it a description, and an input_schema and output_schema (JSON Schemas) so that agents can discover and call it: a run's input is checked against input_schema before it starts, and its output must be JSON matching output_schema or the run fails.

delete_workflow

Delete a workflow

Permanently delete a saved workflow. Runs already started are not affected; schedules that use it stop being able to start runs until it is saved again.

輸入參數name必填

list_schedules

List schedules

List the organization's schedules: each starts a saved workflow on a cron timetable. Includes the next start, the last run and the last error.

輸入參數workflow

get_schedule

Get a schedule

Read a schedule: timetable, time zone, input, cost cap, whether it is enabled, its next start and the outcome of its last start.

輸入參數id必填

create_schedule

Create a schedule

Start a saved workflow on a timetable. Needs an administrator key. Each start is a run billed to the organization, with the cost cap given here (or the default). Use preview_schedule first to check the timetable. A schedule pauses itself after repeated failed starts. An organization can have 50 schedules.

update_schedule

Update or pause a schedule

Change a schedule; only the fields you give change. Needs an administrator key. Set enabled to false to pause it and to true to resume it (resuming clears the failures that paused it). A new timetable counts from now.

輸入參數id必填cronnameinputenabledtimezoneworkflowmax_cost_microsskip_if_running

delete_schedule

Delete a schedule

Permanently delete a schedule. Needs an administrator key. Runs it already started are not affected. To stop it for a while, pause it with update_schedule instead.

輸入參數id必填

preview_schedule

Preview a timetable

Check a cron expression and time zone and return the next five start times (UTC), without saving anything.

輸入參數cron必填timezone

run_schedule

Run a schedule now

Start the schedule's workflow now, outside its timetable, with the schedule's input and cost cap. Returns the queued run (follow it with wait_for_run); each call starts another run and is billed like any run.

輸入參數id必填

list_files

List files

List the files saved in the organization: id, name, size, content type and creation time. Reference a file by id in a run's or workflow's files. Read-only; upload and delete files through the REST API.

無需輸入參數。
