Implementation Reference

• src/mcp_github/github_integration.py:312-367 (handler)

  The core handler function implementing the 'list_open_issues_prs' tool logic. It queries GitHub's search API to retrieve open PRs or issues filtered by repo owner, with pagination and customizable filtering options.
  def list_open_issues_prs( self, repo_owner: str, issue: Literal['pr', 'issue'] = 'pr', filtering: Literal['user', 'owner', 'involves'] = 'involves', per_page: Annotated[PerPage, "Number of results per page (1-100)"] = 50, page: int = 1 ) -> Dict[str, Any]: """ Lists open pull requests or issues for a specified GitHub repository owner. Args: repo_owner (str): The owner of the repository. issue (Literal['pr', 'issue']): The type of items to list, either 'pr' for pull requests or 'issue' for issues. Defaults to 'pr'. filtering (Literal['user', 'owner', 'involves']): The filtering criteria for the search. Defaults to 'involves'. per_page (Annotated[int, PerPage]): The number of results to return per page, range 1-100. Defaults to 50. page (int): The page number to retrieve. Defaults to 1. Returns: Dict[str, Any]: A dictionary containing the list of open pull requests or issues, depending on the value of the `issue` parameter. None: If an error occurs during the request. Error Handling: Logs an error message and prints the traceback if the request fails or an exception is raised.

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

  Dynamic registration of all public methods from the GitHubIntegration instance (including list_open_issues_prs) as MCP tools via FastMCP.add_tool().
  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/github_integration.py:35-36 (schema)

  Pydantic validator defining the schema constraint for the 'per_page' parameter (1-100). Used in the tool's Annotated type hint.
  PerPage = conint(ge=1, le=100)
