Ask

Start Claude Code and ask in plain words, for example “How visible is my brand in AI answers right now?” or “What should we fix first?”. Claude asks before it uses a Prefer tool the first time.
To keep the key out of your shell history, read it into a variable first: run read -rs PREFER_KEY, paste the key, then use --header "Authorization: Bearer $PREFER_KEY" in the command above.

​
Skills as slash commands

Prefer’s skills arrive as prompts, which Claude Code lists as slash commands under the server’s name. Type /prefer: to see them, for example /prefer:prefer_weekly_pulse for a weekly AI visibility pulse or /prefer:prefer_competitor_radar to see where a rival beats you.

​
Where the server is available

claude mcp add adds the server for the folder you run it in. Add --scope user to make Prefer available in every Claude Code session on your machine.

​
Remove it

Run claude mcp remove prefer, and revoke the key in Prefer if you no longer need it.
