Unattended configuration

Publisher documents a persistent stdio MCP process launched by npx or Docker. Sending tools are disabled by default and every delivered message requires human approval.

Source ↗ · Checked 2026-09-19
Authentication and prerequisites

SMTP authentication uses a configured username plus password or app-specific password, which is outside the directory's native authentication taxonomy; sending also retains a human approval gate.

Connection configuration

The documented stdio connection launches npx -y @ni-c/smtp-mcp and supplies SMTP host, user, password, sender, and optional send-policy variables.
