superhuman Codex Plugin

This plugin connects Codex to Superhuman's official Mail MCP server so that email and calendar tasks can be handled directly inside Codex. It is developed by Superhuman and is listed under the Communication category with interactive, read, and write capabilities. Through it, a user can look through inbox contents, produce reply drafts suited to each recipient, check whether sent messages have been opened, and coordinate scheduling. Sample prompts included with the plugin show use cases such as flagging messages needing attention, forwarding invoices, and summarizing responses to an event invitation.
