# Brew MCP Server: Email Marketing for AI Agents

Connect ChatGPT, Claude, Cursor, or any AI agent to Brew over MCP. Agents generate, send, automate, and analyze on-brand email.

Canonical: https://brew.new/mcp

## What 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 runs the full email-marketing cycle, backed by the same brand and data as the Brew app.

## What your agent can do

- Generate and iterate on on-brand email designs
- Send and schedule campaigns and test sends through verified domains
- Build automations: wire triggers to multi-step flows, test, publish, and fire events
- Manage contacts, custom fields, and saved audiences (segments)
- Read delivery, open, click, bounce, and automation analytics
- Generate on-brand images and GIFs and render HTML previews

## Connect

In ChatGPT, enable Developer mode under Settings → Security and login. Then open Settings → Plugins, select `+`, and create Brew with OAuth using this server URL:

```
https://brew.new/api/mcp
```

Sign in to Brew, select a brand, and approve the disclosed full-brand access. Start a new chat, enable `@Brew` from the Plugins menu, and call `get_brew_capabilities`. If an older cached plugin reports an invalid schema, refresh its actions; remove and re-add Brew only after the corrected endpoint is deployed and only if refresh does not work.

For another OAuth-capable MCP client, add the same server URL and complete the same Brew sign-in and brand selection.

If your client does not support OAuth connectors yet, add the same URL to its `mcpServers` config and authenticate with a brand-scoped Brew API key from Settings → API instead:

```json
{
  "mcpServers": {
    "brew": {
      "url": "https://brew.new/api/mcp",
      "headers": { "Authorization": "Bearer brew_YOUR_API_KEY" }
    }
  }
}
```

## Compose with your CRM

Brew is the AI-native ESP: the durable email memory and sending infrastructure for agents. Pair it with a CRM or enrichment MCP (Clay, Attio, and others) to enrich contacts, build intelligent segments, and send personalized email: enrich → segment → design → send → measure → re-segment.

## Workflows

The server ships guided prompts and a discovery tool (`get_brew_capabilities`) so agents chain tools in the right order: launch a campaign, build a segment and send, set up an automation, analyze performance, and personalize with a CRM MCP.
