Strudel MCP Server

Instructions

Implementation Reference

• src/server/EnhancedMCPServerFixed.ts:738-741 (handler)

  Executes the 'append' tool: validates the code length, retrieves the current pattern safely, appends the new code with a newline, and writes the updated pattern back.

  case 'append':
    InputValidator.validateStringLength(args.code, 'code', 10000, true);
    const current = await this.getCurrentPatternSafe();
    return await this.writePatternSafe(current + '\n' + args.code);

• src/server/EnhancedMCPServerFixed.ts:93-102 (registration)

  Registers the 'append' tool with its name, description, and input schema in the getTools() method.

  {
    name: 'append',
    description: 'Append code to current pattern',
    inputSchema: {
      type: 'object',
      properties: {
        code: { type: 'string', description: 'Code to append' }
      },
      required: ['code']
    }

• src/server/EnhancedMCPServerFixed.ts:96-101 (schema)

  Defines the input schema for the 'append' tool, requiring a 'code' string parameter.

  inputSchema: {
    type: 'object',
    properties: {
      code: { type: 'string', description: 'Code to append' }
    },
    required: ['code']

• src/StrudelController.ts:423-432 (helper)

  Helper method in StrudelController that appends code to the current pattern by fetching it, concatenating, and writing back (similar logic to the tool handler).

  async appendPattern(code: string): Promise<string> {
    if (!this._page) {
      throw new Error('Browser not initialized. Run init tool first.');
    }
  
    const current = await this.getCurrentPattern();
    const newPattern = current + '\n' + code;
  
    return this.writePattern(newPattern);
  }
