• src/servicenow_mcp/tools/knowledge_base.py:517-568 (handler)

  The core handler function implementing the publish_article tool. It updates the workflow_state of a knowledge article via a PATCH request to the ServiceNow API.

  def publish_article(
      config: ServerConfig,
      auth_manager: AuthManager,
      params: PublishArticleParams,
  ) -> ArticleResponse:
      """
      Publish a knowledge article.
  
      Args:
          config: Server configuration.
          auth_manager: Authentication manager.
          params: Parameters for publishing the article.
  
      Returns:
          Response with the published article details.

• src/servicenow_mcp/tools/knowledge_base.py:73-79 (schema)

  Pydantic BaseModel defining the input schema/parameters for the publish_article tool.

  class PublishArticleParams(BaseModel):
      """Parameters for publishing a knowledge article."""
  
      article_id: str = Field(..., description="ID of the article to publish")
      workflow_state: Optional[str] = Field("published", description="The workflow state to set")
      workflow_version: Optional[str] = Field(None, description="The workflow version to use")

• src/servicenow_mcp/utils/tool_utils.py:743-749 (registration)

  Tool registration in the central get_tool_definitions() function, associating the tool name with its handler, schema, description, and serialization method.

  "publish_article": (
      publish_article_tool,
      PublishArticleParams,
      str,  # Expects JSON string

  ),

• src/servicenow_mcp/utils/tool_utils.py:174-175 (registration)

  Import of the publish_article handler aliased as publish_article_tool for use in tool registration.
