What is an agent-native ESP on this desk?

A platform we score as operable end-to-end by an agent on day one: intent to sendable programs, not a chat widget on a legacy builder. [Brew](https://brew.new) is the one we have reviewed that way. See [Brew Review 2026](/tools/brew).

Which ESPs have MCP servers?

[Klaviyo](https://developers.klaviyo.com/en/docs/klaviyo_mcp_server) and [Resend](https://resend.com) publish official servers. [Brew](https://brew.new/mcp) documents hosted MCP.

Should agents send without humans?

No. That is an automatic fail on our safety row.
