Any assistant that supports remote MCP servers: Claude, ChatGPT (developer mode), Gemini CLI, Cursor, VS Code and others.
Your assistant reads the same live prices you see on Cdkeycompares, coupons included. Payment fees and a store's own changes can still move the final price, so check it on the store before paying.
