Implementation Reference

• src/mcp_github/ip_integration.py:73-88 (handler)

  The handler function implementing the get_ipv4_info tool. It fetches IPv4 information from the configured API endpoint (default: https://ipinfo.io/json) using an HTTP GET request and returns the JSON data or an error dictionary.

  def get_ipv4_info(self) -> Dict[str, Any]:
      """
      Get information about an IPv4 address.
      :return: A dictionary containing the IPv4 information.
      """
      try:
          ipv4 = self.get_info(self.ipv4_api_url)
          if not ipv4:
              logging.error("No IPv4 information found.")
              return {}
          return ipv4
      except requests.RequestException as e:
          logging.error(f"Error fetching IPv4 info: {e}")
          logging.debug(e)
          traceback.print_exc()
          return {"error": str(e)}

• src/mcp_github/issues_pr_analyser.py:105-113 (registration)

  Dynamic registration of tools from IPIntegration (self.ip) instance. The register_tools method iterates over public methods of the instance and adds them to the MCP server using mcp.add_tool, including get_ipv4_info.

  def _register_tools(self):
      self.register_tools(self.gi)
      self.register_tools(self.ip)
  
  def register_tools(self, methods: Any = None) -> None:
      for name, method in inspect.getmembers(methods):
          if (inspect.isfunction(method) or inspect.ismethod(method)) and not name.startswith("_"):
              self.mcp.add_tool(method)

• src/mcp_github/issues_pr_analyser.py:67-68 (registration)

  Instantiation of the IPIntegration class instance (self.ip) whose methods are registered as MCP tools.

  self.gi = GI()
  self.ip = IP()

• src/mcp_github/issues_pr_analyser.py:28-28 (registration)

  Import of the IPIntegration class containing the get_ipv4_info handler.

  from .ip_integration import IPIntegration as IP

• src/mcp_github/ip_integration.py:51-71 (helper)

  Helper method used by get_ipv4_info to perform the HTTP request and handle errors.

  def get_info(self, url: str) -> Dict[str, Any]:
    """
    Fetches information from the specified URL using an HTTP GET request.
    Args:
        url (str): The URL to send the GET request to.
    Returns:
        Dict[str, Any]: The JSON response parsed into a dictionary if the request is successful.
        Returns an empty dictionary if the request fails or an exception occurs.
    Error Handling:
        Logs an error message and stack trace if a requests.RequestException is raised during the HTTP request.
    """
      
    try:
        response = requests.get(url, timeout=TIMEOUT)
        response.raise_for_status()
        return response.json()
    except requests.RequestException as e:
        logging.error(f"Error fetching IP info: {e}")
        logging.debug(e)
        traceback.print_exc()
        return {"error": str(e)}
