Implementation Reference

• src/server.py:161-179 (handler)

  The main handler function for the 'get_project_by_slug' tool. It authenticates the session, calls the Taiga API to get the project by slug, and handles errors.

  @mcp.tool("get_project_by_slug", description="Gets detailed information about a specific project by its slug.")
  def get_project_by_slug(session_id: str, slug: str) -> Dict[str, Any]:
      """Retrieves project details by slug."""
      logger.info(
          f"Executing get_project_by_slug '{slug}' for session {session_id[:8]}...")
      taiga_client_wrapper = _get_authenticated_client(session_id) # Use wrapper variable name
      try:
          # Use pytaigaclient syntax: client.resource.get(slug=...)
          project = taiga_client_wrapper.api.projects.get(slug=slug)
          # return project.to_dict() # Remove .to_dict()
          return project # Return directly
      except TaigaException as e:
          logger.error(
              f"Taiga API error getting project by slug '{slug}': {e}", exc_info=False)
          raise e
      except Exception as e:
          logger.error(
              f"Unexpected error getting project by slug '{slug}': {e}", exc_info=True)
          raise RuntimeError(f"Server error getting project by slug: {e}")

• src/server.py:39-52 (helper)

  Shared helper function used by get_project_by_slug (and other tools) to retrieve the authenticated Taiga client wrapper for the session.

  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

• src/server.py:161-161 (registration)

  The @mcp.tool decorator registers the 'get_project_by_slug' function as an MCP tool.

  @mcp.tool("get_project_by_slug", description="Gets detailed information about a specific project by its slug.")
