Implementation Reference

• src/zabbix_mcp_server.py:1482-1491 (handler)

  The handler function for the 'apiinfo_version' tool. It retrieves the Zabbix API version using the ZabbixAPI client and formats the result as JSON.

  def apiinfo_version() -> str:
      """Get Zabbix API version information.
      
      Returns:
          str: JSON formatted API version info

      client = get_zabbix_client()
      result = client.apiinfo.version()
      return format_response(result)
