Implementation Reference

• src/mcp_github/ip_integration.py:90-114 (handler)

  The handler function that implements the core logic of the 'get_ipv6_info' tool. It forces IPv6 resolution and fetches IP information from the configured API endpoint (default: https://v6.ipinfo.io/json), handling errors gracefully.

  def get_ipv6_info(self) -> Dict[str, Any]:
    """
    Retrieves IPv6 information from a specified API endpoint.
    This method temporarily overrides the `allowed_gai_family` method to force the use of IPv6 when making network requests.
    It then attempts to fetch IPv6-related information from the configured API URL.
    Returns:
        dict: A dictionary containing IPv6 information if the request is successful.
              Returns an empty dictionary if no information is found or if an error occurs.
    Error Handling:
        Logs an error message and returns an empty dictionary if a `requests.RequestException` is raised during the fetch operation.
        Also logs the full traceback at the debug level for troubleshooting.
    """

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

  The registration code that dynamically discovers and registers all public methods of the IPIntegration instance (including 'get_ipv6_info') as MCP tools via FastMCP.add_tool().
