Email

1authSTDIOregistry active

Summary

Connects Claude to the Blip disposable email API for creating temporary inboxes and monitoring incoming mail. You get tools to generate random or custom email addresses, poll for new messages, and extract OTP codes or verification links from email bodies. Useful when testing signup flows, automating account creation, or bypassing email verification steps in development workflows. The server talks to either the hosted useblip.email service or your own self-hosted instance. Built on their Kotlin API with real-time delivery via SSE, webhook support with HMAC signatures, and multi-domain routing.
