Implementation Reference

• src/index.ts:1382-1478 (handler)

  The main handler function for the 'get_project_info' tool. Validates input, checks project validity, retrieves Godot version, scans project structure, extracts project name from project.godot, and returns JSON with project metadata.

  private async handleGetProjectInfo(args: any) {
    // Normalize parameters to camelCase
    args = this.normalizeParameters(args);

        'Invalid project path',
        ['Provide a valid path without ".." or other potentially unsafe characters']
