It depends on your tool. In the Claude web or desktop app there's no key and no snippet — BYQ Supply is listed in Claude's connector directory, so you find it, click connect, and sign in with your BYQ account. For Claude Code, Cursor, Codex and Lovable it's three steps: generate your MCP key, paste the snippet for your editor, restart the tool. Claude Code uses a single terminal command, Cursor a JSON config, Codex a TOML config, and Lovable two fields under Settings → MCP. The setup page gives you a ready-made snippet with your key already filled in. See Connecting your AI tool for all of them.
