Implementation Reference

• src/servicenow_mcp/tools/user_tools.py:417-474 (handler)

  The handler function that implements the list_groups tool. It queries the ServiceNow sys_user_group table using the provided parameters for filtering, pagination, and search.

  def list_groups(
      config: ServerConfig,
      auth_manager: AuthManager,
      params: ListGroupsParams,
  ) -> dict:
      """
      List groups from ServiceNow.

          auth_manager: Authentication manager.
          params: Parameters for listing groups.
  
      Returns:
          Dictionary containing list of groups.
