jmap-mcp

A community-built MCP server that provides AI assistants with OAuth access to JMAP-compliant mailboxes. It enables reading, organizing, drafting, and sending emails with zero configuration by automatically discovering the JMAP server via DNS SRV or well-known endpoints. The server handles dynamic OAuth registration and stores only encrypted tokens, ensuring mail sovereignty and compatibility with servers like Stalwart.
