A self-hosted, multi-mailbox MCP server that exposes IMAP/SMTP operations as tools for AI agents, enabling email management like listing folders, reading, searching, sending, and moving messages via natural language.
ai-mail-mcp

notifications-mcp

How to choose
- Prioritize transport: stdio servers run locally; HTTP/remote servers need no install but require network trust.
- Check stars & maintenance: Higher GitHub stars and recent commits usually signal a more reliable project.
- Review security scope: File-system and browser servers can access sensitive data; run them in isolated environments.
- Match your client: Not all MCP clients support every transport; verify compatibility with Claude Desktop, Cursor, or your own agent.
