Environment variables

Auth

1. Sign up at resend.com (free tier: 3,000 emails/month, 100/day).
2. Open API Keys in the dashboard and create a key with Full access.
3. Copy the key (starts with re_) into RESEND_API_KEY.
4. To send from your own address, verify a domain under Domains. For testing, use [email protected] (sender) → [email protected] / [email protected] / [email protected] without domain setup.

Tools (62)

All destructive and send operations use a 2-phase α-gate: the first call returns a confirm_token; supply it on the second call to execute. Tokens expire after 60 seconds. Bulk delete tools accept an array of IDs under one token.
