Implementation Reference

• src/utils/handlers.ts:92-146 (handler)

  The core handler logic for the get_labels_list tool. This anonymous function is generated by createApiHandler and executes todoistApi.get('/labels', {}) since no parameters are required, retrieving the list of personal labels from Todoist REST API.

  const handler = async (args: z.infer<z.ZodObject<T>>): Promise<R> => {
      let finalPath = options.path;
      const pathParams: Record<string, string> = {};
  
      // Extract path parameters (e.g., {id}) and replace them with actual values
      const pathParamRegex = /{([^}]+)}/g;
      let match;
  
      while ((match = pathParamRegex.exec(options.path)) !== null) {
          const fullMatch = match[0]; // e.g., "{id}"
          const paramName = match[1]; // e.g., "id"
  
          if (args[paramName] === undefined) {
              throw new Error(`Path parameter ${paramName} is required but not provided`);
          }
  
          // Validate and encode path parameter using the centralized security function
          const safeParamValue = validatePathParameter(args[paramName], paramName);
          finalPath = finalPath.replace(fullMatch, safeParamValue);
          pathParams[paramName] = String(args[paramName]);
      }
  
      // Collect non-path parameters for query string or request body
      const otherParams = Object.entries(args).reduce(
          (acc, [key, value]) => {
              if (value !== undefined && !pathParams[key]) {
                  acc[key] = value;
              }
              return acc;
          },
          {} as Record<string, any>
      );
  
      // Apply custom parameter transformation if provided
      const finalParams = options.transformParams ? options.transformParams(args) : otherParams;
  
      // Execute the API request based on HTTP method
      let result;
      switch (options.method) {
          case 'GET':
              result = await todoistApi.get(finalPath, finalParams);
              break;
          case 'POST':
              log('POST', finalPath, finalParams);
              result = await todoistApi.post(finalPath, finalParams);
              break;
          case 'DELETE':
              result = await todoistApi.delete(finalPath);
              break;
      }
  
      // Apply result post-processing if provided
      return options.processResult ? options.processResult(result, args) : result;
  };

• src/tools/labels.ts:4-10 (registration)

  Tool registration for get_labels_list, specifying name, empty input schema, GET method, and '/labels' path which triggers the Todoist API call for listing labels.

  createApiHandler({
      name: 'get_labels_list',
      description: 'Get all personal labels from Todoist',
      schemaShape: {},
      method: 'GET',
      path: '/labels',
  });

• src/tools/labels.ts:7-7 (schema)

  Input schema for get_labels_list tool, which is empty object indicating no input parameters are required.

  schemaShape: {},

• src/utils/TodoistClient.ts:51-74 (helper)

  The TodoistClient.get method implementation that performs the actual HTTP GET request to https://api.todoist.com/rest/v2/labels for fetching the labels list.

  async get(endpoint: string, params: Record<string, string> = {}): Promise<any> {
      let url = `${API_BASE_URL}${endpoint}`;
  
      const queryParams = new URLSearchParams();
      for (const [key, value] of Object.entries(params)) {
          if (value) {
              queryParams.append(key, value);
          }
      }
  
      const queryString = queryParams.toString();
      if (queryString) {
          url += `?${queryString}`;
      }
  
      log(`Making GET request to: ${url}`);
  
      const response = await fetch(url, {
          method: 'GET',
          headers: this.getHeaders(),
      });
  
      return this.handleResponse(response);
  }
