Side-by-side comparison of two Model Context Protocol servers — install paths, tools, quality signals, and directory engagement so you can pick the right one for Claude, Cursor, and other MCP clients.
notmuch MCP server. Wraps the notmuch CLI to give your LLM access to a local Maildir: full-text search, tag filtering, thread view, attachment reading (PDF, office docs, .ics), related-thread lookup, and unanswered-mail tracking. Optionally write plain-text drafts into a local maildir (--allow-drafts) or manage tags (--allow-tags). No SMTP, no sendmail.
Unified MCP server for email across Gmail (REST API), Outlook (Microsoft Graph), iCloud, and generic IMAP/SMTP. 24 tools for search, send, organize, and batch-manage emails with built-in OAuth2 and encrypted credential storage.
