Implementation Reference

• mcp_mailchimp/server.py:49-66 (handler)

  The 'ping' tool is defined as an asynchronous function decorated with @mcp.tool(). It validates the Mailchimp API key by making a request to the '/ping' endpoint and returns formatted account information.

  @mcp.tool()
  async def ping() -> str:
      """Validate your Mailchimp API key and get account info (name, email, total subscribers)."""
      mc = get_client()
      try:
          await mc.get("/ping")
          root = await mc.get("/")
          return _fmt({
              "status": "connected",
              "account_name": root.get("account_name", ""),
              "email": root.get("email", ""),
              "account_id": root.get("account_id", ""),
              "total_subscribers": root.get("total_subscribers", 0),
              "data_center": mc.dc,
          })
      except MailchimpError as e:
          return f"Connection failed: {e}"
