Multi-account email MCP server for Gmail, IMAP, and JMAP: search, send, drafts, labels.
Runs locally over stdio
This server isn't hosted — your MCP client launches it from a package registry. Use one of the commands below, or drop the config into your client (e.g. Claude Desktop).
Run
npx -y mailbox-mcp
MCP client config
