JMAP Email

JMAP Email is an MCP (Model Context Protocol) server that exposes JMAP (JSON Meta Application Protocol) email operations to AI assistants and other MCP-compatible clients. It provides structured tools for managing email (querying, retrieving, creating, moving, flagging, deleting), handling mailboxes, sender identities, email submission, and Sieve script operations (for email filtering and automation), closely mapping to the JMAP standard. It integrates with JMAP-compatible email providers (such as Fastmail) and can be deployed as a standalone binary or in Kubernetes environments. Target users include AI agent platforms, developers, and organizations seeking machine-driven, standards-based email and filter management through interoperable AI interfaces, especially for scenarios like email automation, intelligent triage, and mailbox organization.
