Overview

AI-generated overview

Lets an assistant inspect and manage Svix webhook applications, endpoints, messages, delivery attempts, and replays through a hosted endpoint.

What it does
Connects to a hosted Svix MCP endpoint that exposes read tools for listing applications, endpoints, messages, event types, delivery attempts, endpoint stats, background tasks, and API health, plus write tools for creating applications and endpoints, sending and resending messages, and recovering failed messages on an endpoint. Credentials are pasted on first connect and stored per user rather than in config files.
When to use it
Useful when you already use Svix for webhooks and want an assistant to look up delivery failures, inspect attempts and endpoint stats, or create applications, endpoints, and messages without leaving the chat. Less relevant if you do not run Svix or only need occasional manual dashboard checks.
Requirements
A remote MCP endpoint at no local install. A Svix account with credentials, which are pasted on first connect and stored per user. Network access to the hosted endpoint. Free plan allows 100 tool calls per month; Pro is $9/mo or $90/yr for unlimited calls.
Before you install
Write tools create applications and endpoints, send and resend messages, and recover failed messages, so they change data and can trigger real webhook deliveries; confirm them before use. Svix credentials are pasted into the hosted service and stored per user, so consider the provider's handling of those secrets. Usage is metered, and exceeding the free tier requires a paid plan.
