Implementation Reference

• wikipedia_mcp/server.py:137-151 (handler)

  MCP tool handler and registration for 'get_summary'. Delegates to WikipediaClient.get_summary and formats response as dict with title and summary or error.

  @server.tool()
  def get_summary(title: str) -> Dict[str, Any]:
      """
      Get a summary of a Wikipedia article.
  
      Returns a dictionary with the title and summary string. On error,
      includes an error message instead of a summary.

      logger.info(f"Tool: Getting summary for: {title}")
      summary = wikipedia_client.get_summary(title)
      if summary and not summary.startswith("Error"):

  Core implementation of get_summary using wikipediaapi.Wikipedia.page(title).summary, with error handling.

      try:

          return page.summary
      except Exception as e:
          logger.error(f"Error getting Wikipedia summary: {e}")
