Welcome to Stack Auth’s weekly newsletter!

As a reminder, Stack Auth is an open-source project and we don’t put our logo or branding into your components, so we rely on the community to spread the word. If you enjoy using Stack Auth, we’d highly appreciate it if you could let your friends know.

Webhook Testing

We’ve introduced new tools to make testing and implementing webhooks easier than ever. When configuring webhooks in the dashboard, you can now send test events, view improved logs, and access additional debugging features.

ChatGPT MCP Integration

If you use ChatGPT, you can now integrate the Stack Auth MCP to enable deep search and conversational functionality. Follow the setup instructions below to get started.

To get started setting up Stack Auth MCP in ChatGPT, go to chatgpt.com and go to your settings. Under Apps and Connectors, click “Create” in the top right corner. Give the tool a name, such as “Stack Auth MCP”. The URL should be set to:
https://mcp.stack-auth.com/api/internal/mcp

Authentication is not required to use our MCP.

Note: You will have to enable Developer mode to add our MCP. This can be done in Apps and Connectors, scroll down to Advanced settings, and enable Dev mode.
