Implementation Reference

• src/servicenow_mcp/tools/user_tools.py:685-745 (handler)

  The core handler function implementing the 'update_group' tool. It constructs a PATCH request to the ServiceNow sys_user_group table API endpoint to update group details based on provided parameters.

  def update_group(
      config: ServerConfig,
      auth_manager: AuthManager,
      params: UpdateGroupParams,
  ) -> GroupResponse:
      """
      Update an existing group in ServiceNow.
  
      Args:
          config: Server configuration.
          auth_manager: Authentication manager.
          params: Parameters for updating the group.
  
      Returns:
          Response with the updated group details.

• src/servicenow_mcp/tools/user_tools.py:92-103 (schema)

  Pydantic model defining the input parameters for the update_group tool, including group_id (required) and optional fields like name, description, etc.

  class UpdateGroupParams(BaseModel):
      """Parameters for updating a group."""
  
      group_id: str = Field(..., description="Group ID or sys_id to update")
      name: Optional[str] = Field(None, description="Name of the group")

      email: Optional[str] = Field(None, description="Email address for the group")
      active: Optional[bool] = Field(None, description="Whether the group is active")

• src/servicenow_mcp/utils/tool_utils.py:808-814 (registration)

  Registration of the 'update_group' tool in the central tool definitions dictionary used by the MCP server. Maps the tool name to its handler function, input schema, return type hint, description, and serialization method.

  "update_group": (
      update_group_tool,
      UpdateGroupParams,
      Dict[str, Any],  # Expects dict
      "Update an existing group in ServiceNow",
      "raw_dict",
  ),

• src/servicenow_mcp/tools/__init__.py:67-73 (registration)

  Import statement in tools/__init__.py that exposes the update_group function for use across the module.

  from servicenow_mcp.tools.user_tools import (
      create_user,
      update_user,
      get_user,
      list_users,
      create_group,
      update_group,
