Implementation Reference

• wikipedia_mcp/server.py:211-220 (handler)

  MCP tool handler for 'get_related_topics'. Registers the tool via @server.tool() decorator and implements minimal logic by delegating to WikipediaClient.get_related_topics().
  @server.tool() def get_related_topics(title: str, limit: int = 10) -> Dict[str, Any]: """ Get topics related to a Wikipedia article based on links and categories. Returns a list of related topics up to the specified limit. """ logger.info(f"Tool: Getting related topics for: {title}") related = wikipedia_client.get_related_topics(title, limit=limit) return {"title": title, "related_topics": related}
• wikipedia_mcp/wikipedia_client.py:689-745 (helper)

  Core implementation of get_related_topics in WikipediaClient. Fetches the page, extracts links and categories, retrieves summaries for top links up to the limit, and falls back to categories.

• wikipedia_mcp/server.py:211-220 (registration)

  The @server.tool() decorator registers 'get_related_topics' as an MCP tool on the FastMCP server.
  @server.tool() def get_related_topics(title: str, limit: int = 10) -> Dict[str, Any]: """ Get topics related to a Wikipedia article based on links and categories. Returns a list of related topics up to the specified limit. """ logger.info(f"Tool: Getting related topics for: {title}") related = wikipedia_client.get_related_topics(title, limit=limit) return {"title": title, "related_topics": related}
