概覽

AI 產生的概覽

遠端 MCP 伺服器，以 OS 開放資料提供英國郵遞區號查詢、最近郵遞區號、自動完成與距離計算。

可以做什麼
  • 查詢英國郵遞區號及其相關資訊
  • 找出指定位置附近的最近郵遞區號
  • 針對不完整的郵遞區號輸入進行自動完成
  • 計算郵遞區號之間的距離
  • 工具由該 API 的端點產生，並在 tools/list 中回傳
適用情境
適合助理需要解析、驗證或補齊英國地址、尋找附近郵遞區號，或計算英國地點之間距離的情境，例如配送、房地產或位置相關的工作流程。
執行需求
遠端 Streamable HTTP 端點，不需本機執行環境或安裝套件。需要在 RapidAPI 上訂閱 UK PostcodeKit（提供免費方案），並在 X-RapidAPI-Key 標頭中提供 RapidAPI 金鑰，另需 X-RapidAPI-Host 標頭。需要能連線至 RapidAPI 主機的網路。
安裝前請注意
X-RapidAPI-Key 是以標頭傳送的密鑰，請勿寫入共用設定或日誌。用量由 RapidAPI 計量，可能受方案額度或付費層級限制。請求及送出的郵遞區號或位置會經 RapidAPI 傳送給第三方 API。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 UK PostcodeKit，將其新增到工作區。
  2. 連接 Custom headers 憑證。它們會被私密儲存，絕不會在公開頁面上展示。
  3. 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/io.github.OlsOls4%2Fukpostcode/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

Developer utility APIs + remote MCP servers

Thirteen small, focused REST APIs for everyday developer jobs: validating emails, phones and IBANs, IP geolocation, PDFs, images, QR codes, fraud scoring, token counting and more. Each one is its own product on RapidAPI with a free plan, full OpenAPI docs, and a built-in remote MCP server so AI agents (Claude, Cursor, VS Code, n8n, LangChain) can call it as tools.

  • Free tier on every API: subscribe on RapidAPI, copy your key, call it.
  • MCP built in: every API exposes Streamable HTTP MCP at https://<host>.p.rapidapi.com/mcp, and each is listed in the official MCP Registry as io.github.OlsOls4/<kit>.
  • No heavy dependencies on your side: plain HTTPS + JSON from any language or no-code tool.

Also available (newer):

  • CurrencyKit: ECB euro reference exchange rates: latest, historical, time series and currency conversion. RapidAPI · MCP https://currencykit-ecb-exchange-rates-currency-converter.p.rapidapi.com/mcp
  • VATKit: Live EU VAT number checks via VIES with company name/address, VAT formats and EU VAT rates. RapidAPI · MCP https://vatkit-eu-vat-number-check-vies-vat-rates.p.rapidapi.com/mcp

Quickstart (REST)

bash
curl -G "https://calkit-public-holidays-business-days-timezones.p.rapidapi.com/business-days/add" \  -d date=2026-12-23 -d days=5 -d country=GB -d subdiv=ENG \  -H "X-RapidAPI-Key: YOUR_RAPIDAPI_KEY" \  -H "X-RapidAPI-Host: calkit-public-holidays-business-days-timezones.p.rapidapi.com"

Swap the host for any API in the table. Every request goes through RapidAPI with X-RapidAPI-Key and X-RapidAPI-Host.

Quickstart (MCP)

Add any API as a remote MCP server in a client that supports Streamable HTTP with custom headers, for example:

json
{  "mcpServers": {    "calkit": {      "type": "http",      "url": "https://calkit-public-holidays-business-days-timezones.p.rapidapi.com/mcp",      "headers": {        "X-RapidAPI-Key": "YOUR_RAPIDAPI_KEY",        "X-RapidAPI-Host": "calkit-public-holidays-business-days-timezones.p.rapidapi.com"      }    }  }}

The server answers tools/list with that API's endpoints as tools.

What's in this repo

  • main.py and one folder per API (webkit, domainkit, qrkit, ...): the FastAPI service behind all listings.
  • mcpserver.py: the MCP layer that turns each API's routes into tools.
  • openapi/: OpenAPI specs for each API.
  • mcp-registry/: server.json files published to the official MCP Registry.
