It is a Model Context Protocol (MCP) server that exposes Brew to AI agents. Connect it in ChatGPT, Claude, Grok, Cursor, Codex, or any MCP client and your agent can generate and iterate on email designs, send and schedule campaigns, build automations, manage contacts and segments, and read performance analytics, using the same brand and data as the Brew app.

Yes. That is where it shines. Brew is the AI-native ESP: the email memory and sending infrastructure your agent operates. Pair it with a CRM or enrichment MCP (Clay, Attio, and others) to add rich contact context, build intelligent segments, and send highly personalized email. Your agent composes them together.
It covers the email marketing cycle: create, iterate, send, schedule, automate, segment, and analyze, including send-time optimization. You can register a domain, then publish its DNS records at your DNS provider. Contact updates by CSV apply to existing contacts; add new contacts through the in-app import, an integration, or your signup flow. Manage brand logos and transactional domain setup in Brew. An organization connection also lets an administrator extract a new brand from its website.
