Implementation Reference

• src/index.ts:333-371 (handler)

  Handler function for the 'create_subdirectory' tool. Validates the input name parameter, retrieves the download directory from config, constructs the full path, creates the subdirectory using fs.ensureDir, and returns a success message or error.

  // Create subdirectory
  if (request.params.name === 'create_subdirectory') {
    const subdirectoryName = request.params.arguments?.name;
  
    if (!subdirectoryName || typeof subdirectoryName !== 'string') {
      throw new McpError(
        ErrorCode.InvalidParams,
        'A valid subdirectory name must be provided'
      );
    }
  
    try {
      const config = getConfig();
      const newSubdirectoryPath = path.join(config.downloadDirectory, subdirectoryName);
  
      // Create the subdirectory
      await fs.ensureDir(newSubdirectoryPath);
  
      return {
        content: [
          {
            type: 'text',
            text: `Subdirectory created: ${newSubdirectoryPath}`
          }
        ]
      };
    } catch (error) {
      const errorMessage = error instanceof Error ? error.message : 'Unknown error';
      return {
        content: [
          {
            type: 'text',
            text: `Failed to create subdirectory: ${errorMessage}`
          }
        ],
        isError: true
      };
    }
  }

• src/index.ts:170-179 (schema)

  Input schema definition for the 'create_subdirectory' tool, specifying the required 'name' parameter as a string.

  inputSchema: {
    type: 'object',
    properties: {
      name: {
        type: 'string',
        description: 'Name of the subdirectory to create'
      }
    },
    required: ['name']
  }

• src/index.ts:167-180 (registration)

  Registration of the 'create_subdirectory' tool in the ListTools response, including name, description, and input schema.

  {
    name: 'create_subdirectory',
    description: 'Create a new subdirectory in the root download folder',
    inputSchema: {
      type: 'object',
      properties: {
        name: {
          type: 'string',
          description: 'Name of the subdirectory to create'
        }
      },
      required: ['name']
    }
