Best for
  • Users who need multi-account email management
  • Users who need real-time email monitoring and AI triage
  • Users who need email scheduling and calendar features
  • Users who want integration with multiple MCP clients (Claude, Cursor, etc.)
  • Developers needing quick, API-key-free web search capabilities
  • Privacy-conscious users who prefer local search execution
  • AI application development with Claude Desktop or Claude Code
Not for
  • Users who only need basic read/send email (may be overkill)
  • Email services that do not use IMAP/SMTP
  • Users who need production-grade stability and are concerned about experimental OAuth2
  • Enterprise applications requiring high-scale, reliable search APIs
  • Users needing advanced search features like custom ranking or filters
  • Accessing sites blocked by TLS fingerprinting without installing the optional browser backend
Required permissions
  • Read emails and mailbox information
  • Send emails
  • Manage emails (move, delete, flag)
  • Manage labels
  • Access local calendar (macOS/Linux)
  • Create OS-level scheduled tasks via scheduler install
  • Send desktop notifications and webhook requests
  • Outbound network access to DuckDuckGo and other websites
  • Reads environment variables for SafeSearch, region, and CA certificates
  • Optionally reads a CA certificate file (for TLS-intercepting proxies)
Risks and side effects
  • Requires storing email credentials (app passwords or OAuth2 tokens)
  • Broad access: can read, send, delete all emails
  • Experimental OAuth2 may be unstable
  • Scheduled emails depend on machine being online, otherwise may be missed
  • Desktop notifications may require extra permissions
  • Search endpoints may occasionally return empty results or errors, especially when blocked
  • Content fetching may be subject to SSRF protection, blocking private or loopback addresses by default
  • Misuse could lead to rate limiting or IP blocking
