One of my projects from over the break: https://t.co/jPllwoSxr0 1. An MCP server hosted on Cloudflare, 2. Which supports dynamic client registration via Auth0 so you can use it with claude code authentication, 3. Which can read your Google Calendar using access tokens, 4. The access tokens are retrieved via Auth0 token vault using token exchange, 5. You connect your Google Calendar account to Auth0 using a single page app for the consent screen, also hosted on Cloudflare, 6. Escalating to push notifications for approval using the Auth0 Guardian app (as an example) for sensitive operations e.g. deleting an event on the calendar This project answered a lot of questions for me as to how a background/async agent could conceptually integrate at a large enterprise while maintaining a strong security posture. It's likely quite tricky to deploy as even though I tried stick to infra-as-code some things can only be done via the Auth0 console. Many thanks to Claude Code for patience and interesting discussions. @trq212 for interesting projects built over the holidays. @yenkel and @whoiskatrin - you might find this interesting.
