• server.js:66-90 (handler)

  Tool registration and handler implementation for "list_campaigns" in server.js. It fetches recent Mailchimp campaigns using the mailchimp SDK and formats the response for the MCP client.

  // --- Tool 3: List Campaigns ---
  server.tool(
    "list_campaigns",
    "List recent Mailchimp campaigns.",
    {
      count: z.number().optional().describe("Number of results (default 10)"),
      status: z.string().optional().describe("Filter by status: save, paused, schedule, sending, sent"),
    },
    async ({ count, status }) => {
      const opts = { count: count || 10 };
      if (status) opts.status = status;
      const response = await mailchimp.campaigns.list(opts);
      const campaigns = response.campaigns.map((c) => ({
        id: c.id,
        type: c.type,
        status: c.status,
        subject_line: c.settings?.subject_line,
        from_name: c.settings?.from_name,
        send_time: c.send_time,
        emails_sent: c.emails_sent,
        recipients: { list_id: c.recipients?.list_id, list_name: c.recipients?.list_name },
      }));
      return { content: [{ type: "text", text: JSON.stringify(campaigns, null, 2) }] };
    }
  );
