Taiga MCP Bridge

Instructions

Implementation Reference

• src/server.py:1027-1056 (handler)

  The handler function for the 'create_milestone' MCP tool. It authenticates the session, validates inputs, and calls the Taiga API via pytaigaclient to create a new milestone (sprint) in the specified project. The @mcp.tool decorator registers it as a tool.

  @mcp.tool("create_milestone", description="Creates a new milestone (sprint) within a project.")
  def create_milestone(session_id: str, project_id: int, name: str, estimated_start: str, estimated_finish: str) -> Dict[str, Any]:
      """Creates a milestone. Requires project_id, name, estimated_start (YYYY-MM-DD), and estimated_finish (YYYY-MM-DD)."""
      logger.info(
          f"Executing create_milestone '{name}' in project {project_id}, session {session_id[:8]}...")
      taiga_client_wrapper = _get_authenticated_client(session_id) # Use wrapper variable name
      if not all([name, estimated_start, estimated_finish]):
          raise ValueError(
              "Milestone requires name, estimated_start, and estimated_finish.")
      try:
          # Use pytaigaclient syntax: client.resource.create(...)
          milestone = taiga_client_wrapper.api.milestones.create(
              project=project_id,             # Changed project_id to project
              name=name,
              estimated_start=estimated_start,
              estimated_finish=estimated_finish
          )
          logger.info(
              f"Milestone '{name}' created successfully (ID: {milestone.get('id', 'N/A')}).")
          # return milestone.to_dict() # Remove .to_dict()
          return milestone # Return directly
      except TaigaException as e:
          logger.error(
              f"Taiga API error creating milestone '{name}': {e}", exc_info=False)
          raise e
      except Exception as e:

• src/server.py:39-52 (helper)

  Helper function used by create_milestone (and other tools) to retrieve and validate the authenticated TaigaClientWrapper from the session store.

      """
      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
