Implementation Reference

• src/index.ts:1798-1811 (handler)

  The main handler logic within the CallToolRequestSchema handler that validates arguments using isCommentIdArgs, calls todoistClient.deleteComment(commentId), and returns success or error response.

  if (name === "todoist_delete_comment") {
    if (!isCommentIdArgs(args)) {
      return { content: [{ type: "text", text: "Invalid arguments for delete_comment" }], isError: true };
    }
    try {
      await todoistClient.deleteComment(args.commentId);
      return { 
        content: [{ type: "text", text: `Comment ${args.commentId} deleted.` }], 
        isError: false 
      };
    } catch (error: any) {
      return { content: [{ type: "text", text: `Error deleting comment: ${error.message}` }], isError: true };
    }
  }

• src/index.ts:676-689 (schema)

  The Tool object definition including name, description, and inputSchema for validating the commentId parameter.

  const DELETE_COMMENT_TOOL: Tool = {
    name: "todoist_delete_comment",
    description: "Delete a comment by its ID",
    inputSchema: {
      type: "object",
      properties: {
        commentId: {
          type: "string",
          description: "The ID of the comment to delete"
        }
      },
      required: ["commentId"]
    }
  };

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

  Registration of all tools including DELETE_COMMENT_TOOL in the ListToolsRequestSchema handler, making the tool discoverable.

  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:1039-1048 (helper)

  Type guard helper function used to validate that the arguments contain a valid string commentId.

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