Mailcycle

Overview

Mailcycle is a Model Context Protocol server that gives your AI agent its own email address. It reads incoming mail, waits for new messages, and lets your agent compose and send replies—all with decryption happening locally on your machine. Any MCP-compatible AI assistant can access Mailcycle's email tools directly, deciding when and how to use them during conversations or agent workflows.

The server runs locally via the npm package mailcycle-mcp, which communicates over stdio. No authentication or external credentials are needed; it works immediately after installation. The latest release is v0.6.2.

Mailcycle is categorized under AI & Agents and integrates with all MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and others. If you maintain Mailcycle, claim this listing to earn a Verified badge and keep the information up to date.
