How to connect a Calendly MCP with Claude Code (4 steps)

Merge offers an integration platform that simplifies connecting various tools, such as Calendly, to products and AI agents via its Merge Agent Handler. This platform allows developers to efficiently handle Calendly's OAuth model, manage token storage, and register webhooks without manual intervention. By utilizing Merge's CLI, developers can authenticate once and manage connections through a single command, enabling them to query scheduled events, access invitee records, and trigger workflows directly from the terminal. The platform supports over 150 connectors, including Calendly, allowing developers to build agents that react to booking data or other scheduling information without storing sensitive credentials locally. This integration is particularly useful for automating actions like creating CRM contacts or sending preparation materials based on booking information.
