letterport

Overview

letterport is a Model Context Protocol server that gives AI agents real email inboxes. Create email addresses, read incoming mail as JSON, and reply within message threads—all through MCP tools that any compatible AI assistant can call directly during conversations or agent runs.

The server runs as a remote endpoint at https://api.letterport.dev/mcp with no local installation required. You'll need an API key to authenticate. The latest release is v1.0.0, available through the vendor at https://letterport.dev/guides/claude-code-email.html.

letterpot appears in the AI & Agents category on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and others. If you maintain letterport, claim this listing to verify ownership and keep the information current.
