Implementation Reference

• src/index.ts:1550-1563 (handler)

  Handler implementation for todoist_get_label tool: validates arguments with isLabelIdArgs, calls todoistClient.getLabel(labelId), formats response with formatLabel, and handles errors.

  if (name === "todoist_get_label") {
    if (!isLabelIdArgs(args)) {
      return { content: [{ type: "text", text: "Invalid arguments for get_label" }], isError: true };
    }
    try {
      const label = await todoistClient.getLabel(args.labelId);
      return { 
        content: [{ type: "text", text: `Label details:\n${formatLabel(label)}` }], 
        isError: false 
      };
    } catch (error: any) {
      return { content: [{ type: "text", text: `Error getting label: ${error.message}` }], isError: true };
    }
  }

• src/index.ts:305-315 (schema)

  Tool schema definition for todoist_get_label, specifying input as object with required labelId string.

  const GET_LABEL_TOOL: Tool = {
    name: "todoist_get_label",
    description: "Get a specific label by its ID.",
    inputSchema: {
      type: "object",
      properties: {
        labelId: { type: "string", description: "The ID of the label to retrieve." }
      },
      required: ["labelId"]
    }
  };

• src/index.ts:1083-1121 (registration)

  Registration of todoist_get_label (as GET_LABEL_TOOL) in the listTools response handler, included in the tools array.

  server.setRequestHandler(ListToolsRequestSchema, async () => ({
    tools: [
      // Task tools
      CREATE_TASK_TOOL,
      QUICK_ADD_TASK_TOOL,
      GET_TASKS_TOOL,
      GET_TASK_TOOL,
      UPDATE_TASK_TOOL,
      DELETE_TASK_TOOL,
      COMPLETE_TASK_TOOL,
      REOPEN_TASK_TOOL,
      SEARCH_TASKS_TOOL,
      MOVE_TASK_TOOL,
      BULK_MOVE_TASKS_TOOL,
      // Project tools
      GET_PROJECTS_TOOL,
      GET_PROJECT_TOOL,
      CREATE_PROJECT_TOOL,
      UPDATE_PROJECT_TOOL,
      DELETE_PROJECT_TOOL,
      // Section tools
      GET_SECTIONS_TOOL,
      CREATE_SECTION_TOOL,
      UPDATE_SECTION_TOOL,
      DELETE_SECTION_TOOL,
      // Label tools
      CREATE_LABEL_TOOL,
      GET_LABEL_TOOL,
      GET_LABELS_TOOL,
      UPDATE_LABEL_TOOL,
      DELETE_LABEL_TOOL,
      // Comment tools
      CREATE_COMMENT_TOOL,
      GET_COMMENT_TOOL,
      GET_COMMENTS_TOOL,
      UPDATE_COMMENT_TOOL,
      DELETE_COMMENT_TOOL,
    ],
  }));

• src/index.ts:982-992 (helper)

  Type guard helper function isLabelIdArgs used to validate input arguments for the todoist_get_label handler.

  function isLabelIdArgs(args: unknown): args is {
    labelId: string;
  } {
    return (
      typeof args === "object" &&
      args !== null &&
      "labelId" in args &&
      typeof (args as { labelId: string }).labelId === "string"
    );
  }

• src/index.ts:727-729 (helper)

  Helper function formatLabel used to format the label details in the response.

  function formatLabel(label: any): string {
    return `- ${label.name} (ID: ${label.id})${label.color ? `\n  Color: ${label.color}` : ''}${label.isFavorite ? `\n  Favorite: Yes` : ''}${label.order ? `\n  Order: ${label.order}`: ''}`;
  }
