Manage audiences, subscribers, campaigns and email marketing workflows. Create and monitor campaigns, automate outreach and work with customer engagement data through Mailchimp.
Claude is Anthropic's AI assistant, available as a desktop app and in Cowork. It supports custom connectors, so it can call MCP servers directly from a chat.
This guide connects Mailchimp to Claude Desktop through MewCP, so Claude Desktop can use Mailchimp's 28 tools, like list_automations, get_automation_info and list_automated_emails, without your Mailchimp credentials ever reaching the app.
Mailchimp signs in through managed OAuth. MewCP stores the token encrypted, refreshes it before it expires and injects it only at call time. Your agent never holds it, so it can never leak it.

Other clients
Mailchimp works the same way in every client below. Pick yours for its own guide.
Free to start.
Scope access to the exact Mailchimp tools and accounts you allow, work and personal side by side. Anything outside that scope is refused at call time, even when the model asks for it.
Each call is logged: what ran, on which account, and whether it worked. Failures come back structured, so the agent knows whether to retry instead of guessing.
Every app sits behind one secure MCP URL, and there is no server for you to deploy or keep running. Add an integration in the dashboard and it is live on the next call, with no config to change and no new credentials to wire up. Tools load only when a task needs them, so your agent stays fast and focused however many apps you connect.
In Claude, open Settings → Connectors, then choose Add custom connector.
Name it "mewcp" and paste the URL.
A browser window opens the first time the client connects. Sign in and approve access. No API key needed.
Start a new chat and ask: "List the tools you can use from MewCP." You should see your connected apps.

Updates the name, HTML, or folder of an existing Classic template. This overwrites the current name and HTML with the values you provide (folder_id is only changed if given) — the original state is not stored by the API after the call. The response includes both the before and after state so you have a full record of what changed.
