概览

AI 生成的概览

托管的 Svix MCP 服务器，让助手查看和管理 Webhook 应用、端点、消息、投递尝试与重放。

可以做什么
  • 列出并获取应用、端点与事件类型，包括端点 URL、订阅事件和 JSON schema
  • 按应用、端点或消息列出消息与投递尝试，含状态、响应码和响应体
  • 读取端点投递统计并检查 Svix API 健康状态
  • 创建应用并注册 Webhook 端点
  • 向应用已订阅的端点发送消息、向单个端点重发某条消息，或按时间戳重放失败消息
  • 跟踪后台任务并查看用量或订阅状态
适用场景
适合排查 Webhook 为何未送达、查看某客户端点的投递健康状况，或在不离开助手的情况下配置并发送 Webhook。适用于已使用 Svix 做 Webhook 投递的团队。
运行要求
通过 streamable HTTP 访问的远程 MCP 端点，无需本地安装。使用 OAuth 登录，首次连接时需粘贴 Svix 凭据，凭据按用户存储。不要在客户端配置中添加 Authorization 头或 API key。免费方案每月 50 次工具调用。
安装前请注意
写入类工具会改动真实数据：创建应用和端点、发送会真实投递到客户 URL 的消息、重发以及重放失败消息。Svix 凭据由托管服务商存储。付费方案（Pro、Pro+）通过支付链接计费，升级会立即收取差价且当期不退款。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Svix MCP by usefulapi，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

交给智能体安装

把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。

阅读 https://sourceweft.com/mcp/io.usefulapi%2Fsvix/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。

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].
