Implementation Reference

• main.py:265-267 (registration)

  Registers the 'move_article_to_trash' tool with the FastMCP server using the @mcp.tool decorator, providing a description.
  @mcp.tool( description="Delete an article by moving to the trashed state on the Joomla website, allowing recovery." )
• main.py:268-315 (handler)

  The main handler function for the 'move_article_to_trash' tool. It verifies the article exists, optionally checks the title matches, ensures it's not already trashed, and delegates to manage_article_state(article_id, -2) to update the state to trashed.

  Supporting function 'manage_article_state' used by move_article_to_trash to perform the actual state update to trashed (-2). This is a shared utility for managing article states.
