A side-by-side look at the MCP Relight & Harmonize and Techtenstein Bg MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose MCP Relight & Harmonize for multimedia process work as a local process; choose Techtenstein Bg for multimedia process as a local process. You can also run both side by side in one mcpServers block.
