🛠️ Fixed

Fixed

• OAuth sign-in against CDN-protected servers — connecting to an OAuth-secured MCP server behind bot protection (like Interactive Brokers' api.ibkr.com) failed with "No authorization support detected". MCP Peek's requests carried no User-Agent header, which those CDNs reject - every request the app makes now properly identifies itself, and the full authorize flow (discovery → registration → sign-in → token exchange) works.

Changed

• Updated the MCP engine - progress notifications for tool runs and proxied clients keep working exactly as before
