If it does not appear, check that r4ck is connected and that you are looking at its prompts rather than its tools.
Claude on the web takes a remote URL and completes OAuth in the browser. For a packaged server use Claude Desktop or Claude Code instead. Claude.ai docs
Same prompt, other clients
Read from the server itself, by connecting to it and calling prompts/list on 11 November 2026.
A listing does not declare its prompts, so asking is the only way to know them, and this
is what the server actually offers rather than what its listing claims. Names only are
stored; connect the server for each prompt's arguments.
