Taiga MCP Bridge

Instructions

Implementation Reference

• src/server.py:557-575 (handler)

  The handler function for the MCP tool 'delete_task'. It authenticates the session, calls the Taiga API to delete the task by ID, logs the action, and returns a success status or raises appropriate errors.

  @mcp.tool("delete_task", description="Deletes a task by its ID.")
  def delete_task(session_id: str, task_id: int) -> Dict[str, Any]:
      """Deletes a task by ID."""
      logger.warning(
          f"Executing delete_task ID {task_id} for session {session_id[:8]}...")
      taiga_client_wrapper = _get_authenticated_client(session_id) # Use wrapper variable name
      try:
          # Use pytaigaclient syntax: client.resource.delete(id=...)
          taiga_client_wrapper.api.tasks.delete(id=task_id)
          logger.info(f"Task {task_id} deleted successfully.")
          return {"status": "deleted", "task_id": task_id}
      except TaigaException as e:
          logger.error(
              f"Taiga API error deleting task {task_id}: {e}", exc_info=False)
          raise e
      except Exception as e:
          logger.error(
              f"Unexpected error deleting task {task_id}: {e}", exc_info=True)
          raise RuntimeError(f"Server error deleting task: {e}")

• src/server.py:39-52 (helper)

  Helper function used by delete_task (and other tools) 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

• src/server.py:557-557 (registration)

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

  @mcp.tool("delete_task", description="Deletes a task by its ID.")
