This is calendar/ietf-picker, an app on Vibes DIY. An AI assistant can work with this app: add the Vibes DIY connector, at https://vibes-diy-mcp-dev.jchris.workers.dev/mcp, to the assistant. Give the connector this app's address, calendar/ietf-picker, and the assistant can read and write this app's data as the person who connected it, with exactly the access that person has.
