Nylas connects your application to every email inbox and calendar in the world. The Nylas v3 platform provides REST APIs for email, calendar, contacts, scheduling, meeting notetaking, authentication, and administration across Google, Microsoft, Exchange, iCloud, Yahoo and any IMAP provider. Official SDKs cover Node.js, Python, Ruby and Kotlin/Java, alongside a CLI, a hosted MCP server, and Agent Accounts that provision a Nylas-hosted mailbox and calendar for autonomous agents without requiring an OAuth flow.
