Calendly

This connects Claude to Calendly's scheduling API through Membrane's auth layer, so you can query events, list invitees, check user availability, and create scheduling links without handling OAuth tokens yourself. It's built for sales teams and customer success folks who want to automate meeting workflows. The skill wraps common operations like listing scheduled events and managing webhooks, but also lets you proxy raw requests when the pre-built actions don't cover your edge case. Membrane handles credential refresh automatically, which matters more than it sounds when you're dealing with long-running automations. Works on the free tier.
