Implementation Reference

• wikipedia_mcp/server.py:97-116 (handler)

  The MCP tool handler for 'test_wikipedia_connectivity', registered via @server.tool() decorator. It calls the underlying WikipediaClient.test_connectivity() method and formats the response time.
  @server.tool() def test_wikipedia_connectivity() -> Dict[str, Any]: """ Provide diagnostics for Wikipedia API connectivity. Returns the base API URL, language, site information, and response time in milliseconds. If connectivity fails, status will be 'failed' with error details. """ logger.info("Tool: Testing Wikipedia connectivity") diagnostics = wikipedia_client.test_connectivity() # Round response_time_ms for nicer output if present if ( diagnostics.get("status") == "success" and "response_time_ms" in diagnostics and isinstance(diagnostics["response_time_ms"], (int, float)) ): diagnostics["response_time_ms"] = round(float(diagnostics["response_time_ms"]), 3) return diagnostics

  Supporting method in WikipediaClient class that performs the actual connectivity test by querying the Wikipedia API siteinfo endpoint, measures response time, and handles exceptions.
