Requirements
- A Brew account with access to your brand
- A Claude account that can add custom connectors, or Claude Code installed for the terminal path
- A browser to sign in with Brew and approve access
Connect Claude Desktop or Web
1
Add the Brew connector
Open Customize → Connectors → + Add → Add custom connector. If Brew is already listed, use that connection instead.Name the connector Brew and enter:Select Continue and review the detected authentication settings. Choose Sign in now or Sign in when needed. If Claude offers an OAuth client choice, select Register automatically for Brew’s automatic client registration.Finish adding the connector. This path uses browser sign-in, so leave fixed API-key headers empty.
On Team or Enterprise, an authorized administrator adds Brew first: Organization settings → Connectors → Add → Custom → Web. Members then connect individually.
2
Sign in with Brew
Select Connect on the Brew connector. In the browser, sign in with Brew and choose the brand you want Claude to use. Review the requested access before approving it.
3
Enable Brew in your conversation
Return to Claude. Open the conversation’s + → Connectors menu and enable Brew.Paste the verification prompt below before asking Claude to create anything.
Verify Your Brand
Replace the brackets and send:brand_id for brand-scoped tools. Ask Claude to list your brands and use the selected ID, or reconnect to one brand. MCP Authentication and Scoping owns those rules.
Connect Claude Code
Run this in your terminal:--scope user makes the server available across your projects. Omit it for the current project’s local configuration.
Start Claude Code and open /mcp. Select Brew and complete browser authentication, choosing your brand. Confirm that Brew is connected, then run the brand verification prompt.
Adding the server URL saves configuration; authentication and a successful tool call complete the setup. See Claude Code’s MCP guide for client configuration and policy options.
Create and Review a Draft
Email generation uses Brew credits. After verification, ask for one draft:create_email. If it returns generating, Claude should poll get_email with the returned emailId and runId. Repeating creation starts another billed design.
Open the preview and Brew link. Check the facts, branding, images, and links before approving further work. For a focused revision, send:
edit_email and also use credits. A rename, subject change, or folder move alone uses the free update_email_metadata tool.
Set Your Approval Boundaries
Give Claude instructions for later work:confirmed: true and its confirmation_id.
Always include idempotency_key in send_email, including test sends. Reuse the same key and send inputs when confirming or retrying that send. Use a fresh key for a separate intended send.
See Safe Retries for the full contract.
Run Your Email Ops from an AI Agent covers the full draft, review, test, and send workflow. MCP Workflows covers audiences, automations, and analytics. Neither a draft nor an accepted send proves inbox delivery.
Watch the Walkthrough
Connect Claude with MCP shows the connector, brand authorization, email creation, and a scheduled send. It was recorded before Brew MCP 3.0; the video page explains the changed contact tools. Use this guide and the current tool catalog for today’s behavior.Troubleshooting
Disconnect Brew
Remove the custom connector from Customize → Connectors when you no longer want it in Claude. Revoke the matching authorization in Brew under Settings → MCP → Connected via OAuth to end that grant. For Claude Code configuration, useclaude mcp remove brew --scope user if you added it with user scope. Revoke its Brew grant too.
