How to Use the Mailchimp MCP in Claude Code

Q: How do I connect Mailchimp to Claude Code?

Run claude mcp add --transport http mailchimp -- . Ensure your transport and scope flags precede the server name. The config saves to /.claude.json.

Q: How does Claude Code handle Mailchimp list management?

The CLI uses listaudiences to map your lists, then targets specific IDs with addmember or listmembers. You can script it to clean up unsubscribed users automatically.

Q: Is there a way to test campaigns before sending through the MCP server?

Instruct the agent to run createcampaign and stop. You can then use getcampaign to verify the draft details in your terminal before approving a live send.

Manage Mailchimp audiences and trigger campaigns directly from your terminal using Claude Code over an MCP connection.

Perplexity

Headless audience syncing

Pipe your database dumps straight into a shell script and let Claude Code handle the synchronization. It iterates through your records and fires `add_member` to update subscription statuses in the background. You can run this as a cron job. The CLI tool calls `list_members` to compare your local database against the live list, tagging new signups and cleaning bounced contacts without manual intervention.

Trigger campaigns via MCP Server

Wire your deployment pipeline to announce new releases automatically. Claude Code reads your changelog, formats the HTML, and executes `create_campaign` to stage the announcement. Once your CI/CD checks pass, the script hits `send_campaign` to dispatch the email. The action triggers a live send immediately, keeping your users updated the second code hits production.

Terminal-native reporting

Check your marketing performance without leaving the command line. Run a quick prompt to fetch yesterday's stats, and the agent executes `get_report` to return open and click metrics as raw JSON. If marketing asks why a specific user stopped receiving emails, you just tell the CLI to investigate. It runs `search_members` to find the contact and returns their exact status and merge tags to your stdout.
