Protonmail

Protonmail MCP Server enables Claude Desktop and Cline VSCode extension to send emails through Protonmail's SMTP service. Developed by amotivv, inc. (creators of Memory Box), this TypeScript implementation provides a single tool for sending emails with support for multiple recipients, CC/BCC functionality, and both plain text and HTML content. The server requires Protonmail SMTP credentials configured as environment variables and includes comprehensive error handling and logging capabilities, making it particularly valuable for workflows where AI assistants need to communicate via email without leaving the conversation interface.
