概覽

AI 產生的概覽

託管的 Svix MCP 伺服器，讓助理檢視與管理 Webhook 應用程式、端點、訊息、投遞嘗試與重放。

可以做什麼
  • 列出並取得應用程式、端點與事件類型，包含端點 URL、訂閱事件與 JSON schema
  • 依應用程式、端點或訊息列出訊息與投遞嘗試，含狀態、回應碼與回應內容
  • 讀取端點投遞統計並檢查 Svix API 健康狀態
  • 建立應用程式並註冊 Webhook 端點
  • 向應用程式已訂閱的端點傳送訊息、向單一端點重送某則訊息，或依時間戳重放失敗訊息
  • 追蹤背景工作並查看用量或訂閱狀態
適用情境
適合排查 Webhook 為何未送達、查看某客戶端點的投遞健康狀況，或在不離開助理的情況下設定並傳送 Webhook。適用於已使用 Svix 進行 Webhook 投遞的團隊。
執行需求
透過 streamable HTTP 存取的遠端 MCP 端點，無需本機安裝。以 OAuth 登入，首次連線時需貼上 Svix 憑證，憑證依使用者儲存。請勿在用戶端設定中加入 Authorization 標頭或 API key。免費方案每月 50 次工具呼叫。
安裝前請注意
寫入類工具會變更真實資料：建立應用程式與端點、傳送會實際投遞到客戶 URL 的訊息、重送以及重放失敗訊息。Svix 憑證由託管服務商儲存。付費方案（Pro、Pro+）透過付款連結計費，升級會立即收取差額且當期不退款。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Svix MCP by usefulapi，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/io.usefulapi%2Fsvix/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

Svix MCP by usefulapi

Send and debug webhooks — applications, endpoints, messages, delivery attempts and replays. Hosted, no local install.

Live endpoint: https://svix.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://svix.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http svix https://svix.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
json
{  "mcpServers": {    "svix": {      "url": "https://svix.usefulapi.io/mcp"    }  }}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Svix credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/svix/

On first connect you'll paste your Svix credentials. They are validated, stored per-user, and scoped to you — no keys in config files.

Pricing

PlanPriceLimit
Free$050 tool calls / month
Pro$9/mo or $90/yr (2 months free)10,000 tool calls / month
Pro+$39/mo or $390/yr (2 months free)100,000 tool calls / month

Each paid plan covers this server only. Ask your AI to run svix_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with svix_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with svix_upgrade before then undoes the cancel. Or write to [email protected].
