What is Mailgent?
Mailgent focuses on giving artificial intelligence agents the foundational elements needed to function with real-world presence. This includes email handling for sending and receiving messages, secure storage for credentials, and time-based authentication support. A decentralized identifier enables signing and verification while a dedicated wallet handles transactions without external intervention. Developers connect agents via an MCP server or SDK to access these features through scoped tools. The system supports calendar management for scheduling and ensures least-privilege access by default. It streamlines setup by eliminating manual configurations for mailboxes or authentication flows. Usage scales across different plans that track agent activity and resource consumption. Agents can read inboxes, generate codes, create events, and sign requests while maintaining encrypted data handling throughout operations.
