Enhanced Directory Context MCP Server

Instructions

Implementation Reference

• server.js:707-725 (handler)

  The main handler function that implements the create_directory tool. It resolves the directory path relative to the working directory, creates the directory using fs.mkdir (with optional recursive creation), and returns a success message or throws an error.

  async handleCreateDirectory(args) {
    const { path: dirPath, recursive = true } = args;
    const fullPath = path.resolve(this.workingDirectory, dirPath);
    
    try {
      await fs.mkdir(fullPath, { recursive });
      
      return {
        content: [
          {
            type: 'text',
            text: `Directory created: ${dirPath}`,
          },
        ],
      };
    } catch (error) {
      throw new McpError(ErrorCode.InternalError, `Failed to create directory: ${error.message}`);
    }
  }

• server.js:321-334 (schema)

  Input schema definition for the create_directory tool, specifying the path parameter (required) and optional recursive flag.

  inputSchema: {
    type: 'object',
    properties: {
      path: {
        type: 'string',
        description: 'Directory path relative to working directory',
      },
      recursive: {
        type: 'boolean',
        description: 'Create parent directories if needed',
        default: true,
      },
    },
    required: ['path'],

• server.js:318-336 (registration)

  Tool registration in the ListToolsRequestSchema response, defining name, description, and input schema.

  {
    name: 'create_directory',
    description: 'Create a new directory',
    inputSchema: {
      type: 'object',
      properties: {
        path: {
          type: 'string',
          description: 'Directory path relative to working directory',
        },
        recursive: {
          type: 'boolean',
          description: 'Create parent directories if needed',
          default: true,
        },
      },
      required: ['path'],
    },
  },

• server.js:488-489 (registration)

  Switch case in CallToolRequestSchema handler that routes create_directory calls to the handler method.

  case 'create_directory':
    return await this.handleCreateDirectory(args);
