Implementation Reference

• src/tools/unity-mcp-tools.ts:246-263 (registration)

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

  {
    name: 'folder_rename',
    description: 'Rename a folder in Unity project',
    inputSchema: {
      type: 'object',
      properties: {
        oldPath: {
          type: 'string',
          description: 'Current path of the folder'
        },
        newName: {
          type: 'string',
          description: 'New name for the folder'
        }
      },
      required: ['oldPath', 'newName']
    }
  },

• src/tools/unity-mcp-tools.ts:486-497 (handler)

  Handler for 'folder_rename' tool in executeTool method. Validates inputs and delegates to UnityHttpAdapter.renameFolder, then formats success response.

  case 'folder_rename': {
    if (!args.oldPath || !args.newName) {
      throw new Error('oldPath and newName are required');
    }
    const result = await this.adapter.renameFolder(args.oldPath, args.newName);
    return {
      content: [{
        type: 'text',
        text: `Folder renamed successfully:\nOld Path: ${result.oldPath}\nNew Path: ${result.newPath}\nGUID: ${result.guid}`
      }]
    };
  }

• src/adapters/unity-http-adapter.ts:157-159 (helper)

  Core implementation of folder rename via HTTP POST to Unity MCP server endpoint 'folder/rename'.

  async renameFolder(oldPath: string, newName: string): Promise<{ oldPath: string; newPath: string; guid: string }> {
    return this.call('folder/rename', { oldPath, newName });
  }
