protonlite MCP

An unofficial Python client for Proton Mail, Calendar, Contacts, and Drive that includes an optional MCP server. It allows AI agents to interact with Proton services directly via web API without requiring Proton Mail Bridge or a paid plan, supporting end-to-end encryption for reading, sending, and managing emails, events, contacts, and files.
