Taiga MCP Bridge

Instructions

Implementation Reference

• src/server.py:659-677 (handler)

  The main handler function for the 'get_issue' tool. It authenticates the session, retrieves the Taiga client wrapper, fetches the issue by ID using the client's API, and returns the issue details or raises appropriate errors.

  @mcp.tool("get_issue", description="Gets detailed information about a specific issue by its ID.")
  def get_issue(session_id: str, issue_id: int) -> Dict[str, Any]:
      """Retrieves issue details by ID."""
      logger.info(
          f"Executing get_issue ID {issue_id} for session {session_id[:8]}...")
      taiga_client_wrapper = _get_authenticated_client(session_id) # Use wrapper variable name
      try:
          # Issues expects issue_id as a positional argument
          issue = taiga_client_wrapper.api.issues.get(issue_id)
          # return issue.to_dict() # Remove .to_dict()
          return issue # Return directly
      except TaigaException as e:
          logger.error(
              f"Taiga API error getting issue {issue_id}: {e}", exc_info=False)
          raise e
      except Exception as e:
          logger.error(
              f"Unexpected error getting issue {issue_id}: {e}", exc_info=True)
          raise RuntimeError(f"Server error getting issue: {e}")

• src/server.py:659-659 (registration)

  The @mcp.tool decorator registers the 'get_issue' tool with FastMCP, specifying its name and description.

  @mcp.tool("get_issue", description="Gets detailed information about a specific issue by its ID.")

• src/server.py:39-52 (helper)

  Helper function used by get_issue to retrieve and validate the authenticated TaigaClientWrapper from the session store.

  def _get_authenticated_client(session_id: str) -> TaigaClientWrapper:
      """
      Retrieves the authenticated TaigaClientWrapper for a given session ID.
      Raises PermissionError if the session is invalid or not found.
      """
      client = active_sessions.get(session_id)
      # Also check if the client object itself exists and is authenticated
      if not client or not client.is_authenticated:
          logger.warning(f"Invalid or expired session ID provided: {session_id}")
          # Raise PermissionError - FastMCP will map this to an appropriate error response
          raise PermissionError(
              f"Invalid or expired session ID: '{session_id}'. Please login again.")
      logger.debug(f"Retrieved valid client for session ID: {session_id}")
      return client
