Then ask your AI: use rapp-domains to check domain

Install rapp-domains

The server’s own address, for the clients that take one directly. Or connect ahel once and every client you use reads it from one address, with the account kept on ahel rather than in each client’s config.

Claude Code
claude mcp add --transport http --scope user rapp-domains 'https://rapp-agent-builder.azurewebsites.net/domains/mcp'
Run it once in your project, then open /mcp to approve any sign-in the server asks for.
Claude Desktop
https://rapp-agent-builder.azurewebsites.net/domains/mcp
Add a custom connector in Settings, paste this address, and approve the sign-in.
Cursor
cursor://anysphere.cursor-deeplink/mcp/install?name=rapp-domains&config=eyJ1cmwiOiJodHRwczovL3JhcHAtYWdlbnQtYnVpbGRlci5henVyZXdlYnNpdGVzLm5ldC9kb21haW5zL21jcCJ9
Open the link and Cursor adds the server at that address.
ChatGPT
https://rapp-agent-builder.azurewebsites.net/domains/mcp
In Settings, enable Developer mode, create an MCP app, and paste this address. Your plan and workspace must allow custom apps.
Codex
codex mcp add rapp-domains --url 'https://rapp-agent-builder.azurewebsites.net/domains/mcp'
Run it once, then sign in with codex mcp login rapp-domains if the server asks for an account.

From the project's README

As published by kody-w/rapp-chatgpt in README.md. This repository publishes several servers, so only the opening is shown here.

A ChatGPT app that turns an idea or a meeting transcript into a working single-file RAPP agent. ChatGPT's own model writes the agent; this MCP server supplies the template, checks the result, searches the public RAPP Agent Registry, and explains how to run the agent in the free RAPP Brainstem.

It sits on top of the ecosystem and never changes the Brainstem: it reads the public registry and points at the public installer.

MCP endpoint: https://rapp-agent-builder.azurewebsites.net/mcp (streamable HTTP, stateless, JSON responses)
Site, privacy, terms: https://kody-w.github.io/rapp-chatgpt/
