• src/servicenow_mcp/tools/knowledge_base.py:136-195 (handler)

  The main handler function implementing the create_knowledge_base tool. It constructs a POST request to the ServiceNow kb_knowledge_base table with the provided parameters and returns a KnowledgeBaseResponse.

  def create_knowledge_base(
      config: ServerConfig,
      auth_manager: AuthManager,
      params: CreateKnowledgeBaseParams,
  ) -> KnowledgeBaseResponse:
      """

      Args:
          config: Server configuration.
          auth_manager: Authentication manager.
          params: Parameters for creating the knowledge base.
  
      Returns:
          Response with the created knowledge base details.

• src/servicenow_mcp/tools/knowledge_base.py:19-28 (schema)

  Pydantic BaseModel defining the input schema (parameters) for the create_knowledge_base tool, including title, description, owner, etc.

  class CreateKnowledgeBaseParams(BaseModel):
      """Parameters for creating a knowledge base."""
  
      title: str = Field(..., description="Title of the knowledge base")
      description: Optional[str] = Field(None, description="Description of the knowledge base")

      publish_workflow: Optional[str] = Field("Knowledge - Instant Publish", description="Publication workflow")
      retire_workflow: Optional[str] = Field("Knowledge - Instant Retire", description="Retirement workflow")

• src/servicenow_mcp/utils/tool_utils.py:661-667 (registration)

  Registration of the 'create_knowledge_base' tool in the tool_definitions dictionary used by the MCP server, mapping the name to its handler, schema, description, and serialization method.

  "create_knowledge_base": (
      create_knowledge_base_tool,
      CreateKnowledgeBaseParams,
      str,  # Expects JSON string
      "Create a new knowledge base in ServiceNow",
      "json_dict",  # Tool returns Pydantic model
  ),

• src/servicenow_mcp/tools/__init__.py:49-59 (registration)

  Import statement exposing create_knowledge_base from knowledge_base.py in the tools package __init__, making it available for import.

  from servicenow_mcp.tools.knowledge_base import (
      create_article,
      create_category,
      create_knowledge_base,
      get_article,
      list_articles,
      list_knowledge_bases,
      publish_article,
      update_article,
      list_categories,
  )

• src/servicenow_mcp/utils/tool_utils.py:160-162 (registration)

  Import of the handler function aliased as create_knowledge_base_tool for use in tool registration.

      # create_category aliased in function call
      create_knowledge_base as create_knowledge_base_tool,
  )
