概覽

AI 產生的概覽

Voltcast 讓助理取得歐洲日前電價、機率性價格預測、碳強度與最低成本時段最佳化。

可以做什麼
列出支援的歐洲競價區域及其代碼、名稱與能力，僅區域清單不需金鑰。依區域與日期取得日前電價，使用當地貨幣與原生市場結算間隔。取得即時市場價格，與日前曲線分開標示。取得最長 7 天的機率性價格預測，回傳 P50 曲線及帳戶所含的不確定性區間。讀取依即時發電結構計算的碳強度與綠色評分，以及風電與光電發電預測對比實際發電量。依成本排序家庭用電時段，可選填使用者自有的變動電價參數。
適用情境
適合讓助理查詢歐洲電力價格、比較不同區域、依低價或低碳時段安排用電，或在依賴預測前查看公開的預測準確度。
執行需求
遠端 streamable HTTP 端點，或透過 npx 或 Docker 執行的本機 stdio 伺服器。多數工具需要 API 金鑰，以 Authorization Bearer 標頭傳送（本機伺服器使用 VOLTCAST_API_KEY）；list_zones 不需金鑰。部分工具需要付費帳戶等級或相應權益。需要連線至 Voltcast 服務的網路存取。
安裝前請注意
新帳戶須綁定信用卡開始 7 天試用，之後為付費月租方案；部分工具需要 Pro+ 或既有權益。API 金鑰屬於憑證，應妥善保密。預測為機率性，並公開與基準比較，包含預測失準的情況。cheapest_window 的實驗性碳排與均衡模式使用歷史發電結構，並非前瞻性碳預測，也不支持減排聲明。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Voltcast，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/com.voltcast%2Fvoltcast/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。

README

Voltcast MCP Server — European electricity prices, forecasts & carbon

Model Context Protocol server for Voltcast: day-ahead electricity prices for 47 European bidding zones (15-minute native resolution, history to 2015), probabilistic price forecasts whose accuracy is published daily at voltcast.com/accuracy, carbon intensity, and cheapest-window optimization.

Two ways to run it:

1. Hosted endpoint (recommended)

https://voltcast.com/api/mcp

Streamable HTTP transport, protocol 2025-06-18. Server card: /.well-known/mcp.json.

2. Local stdio server (this repo)

bash
VOLTCAST_API_KEY=your_key npx voltcast-mcp

Or with Docker:

bash
docker build -t voltcast-mcp .docker run -i -e VOLTCAST_API_KEY=your_key voltcast-mcp

The stdio server is a thin proxy onto the same REST API — identical tools, auth and rate limits. It starts and answers introspection without a key; list_zones works keyless too.

Auth

Authorization: Bearer <api key>. New accounts start with Home at €9/month after a 7-day card-required trial; existing Free accounts remain grandfathered. list_zones works without a key. The exact hosted-connector walkthrough is at voltcast.com/ai/local-electricity-price.

Honesty, stated plainly

Every forecast the server returns is benchmarked daily against a naive baseline in public — losses included. Zones where the model loses are free to use under the guarantee. Data sources: ENTSO-E Transparency Platform, SMARD.de (CC BY 4.0), attributed in every response.

list_zones

List Zones

List all supported European bidding zones with codes, names, and capabilities. No auth required.

無需輸入參數。

get_prices

Get Prices

Day-ahead electricity prices in each zone's native currency and native market resolution. Connect an existing Voltcast account to access account-scoped data.

get_realtime_prices

Get Realtime Prices

Explicitly labeled real-time market prices (currently WEIM), kept separate from day-ahead curves. Requires an API key.

get_renewables

Get Renewables

Day-ahead wind and solar generation forecasts: the TSO official forecast and Voltcast model with uncertainty bands, realized generation, and disclosed head-to-head verification. Requires the corresponding existing account entitlement.

cheapest_window

Cheapest Window

Rank household action windows by cost using current Voltcast curves and optional user-supplied variable tariff inputs. Experimental carbon/balanced modes use a disclosed trailing historical production-mix profile—not a forward carbon forecast—and support no emissions-reduction claim.
