# Announcing MCP Authentication: secure your MCP servers with PropelAuth

Today, we're excited to show off our Webhook support. Webhooks allow you to reliably receive an HTTP request when a specific action occurs, like a user signing up, joining an organization, or having their role change. Some examples of things you can do include:

- Creating a copy of your users and organizations' information in your DB
- Signing up new users to your mailing list and sending them a welcome email
- Provisioning resources for a user right when they sign up
- Updating your billing information as new users join organizations within your product

To set it up, go to the **Webhook** section of your dashboard. You can set up different endpoints for your **test and production environments** so you can easily distinguish between the two. There's also a full event catalog with examples of what the events look like.

The Webhooks themselves are powered by [Svix](https://www.svix.com/?ref=propelauth.mymidnight.blog), which also handles **automatic retries** and can display a full log of the events your endpoints received.
