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.
Email operating system for agents: a search tool to find the one message by sender/subject/content (no filesystem grep), two-axis triage (importance × urgency), an explainable "Right Now" lane, commitment follow-through, and reviewable drafts. A machine-verifiable hard-stop keeps money/banking-change/first-contact human-only (BEC defense). Zero-auth HTTP sandbox at radmail.ai/api/mcp/sandbox — no account, no key.
Fast MCP server for Apple Mail — 87x faster email fetching via batch JXA and FTS5 search index for 2ms body search. 6 tools: list accounts/mailboxes, get emails with filters, full-text search across all scopes, and attachment extraction.
