From f1d97facbcb4a9fcbe602029ec7eaf49c285b59b Mon Sep 17 00:00:00 2001 From: yusyus Date: Sun, 18 Jan 2026 22:25:35 +0300 Subject: [PATCH] fix: Use download_url from API response instead of constructing URL MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit CRITICAL BUG FIX - Resolves 404 errors when fetching configs from API Root Cause: The code was constructing download URLs manually: download_url = f"{API_BASE_URL}/api/download/{config_name}.json" This fails because the API provides download_url in the response, which may differ from the constructed path (e.g., CDN URLs, version-specific paths). Solution: Changed both MCP server implementations to use download_url from API: download_url = config_info.get("download_url") Added validation check for missing download_url field.
