Rapp Domains tools (3)

write = sends, deletes, buys or posts
  • check_domainFree

    Use when the user wants a domain name, is naming a business or project, or asks whether a domain is taken. Checks up to 20 full domain names (you can suggest variations and check them together) and returns whether each is available and its price.

  • register_domainFree

    Use when the user wants to buy an available domain. Explains how to register it: AI agents pay per call; people ask us and we register it for them. Nothing is bought by this tool.

  • request_serviceFree

    Use when the person wants something none of these tools can do and says yes to passing the request on. Records only the request text they agree to send (no name or contact). Ask before calling it.

What the publisher says

From the Rapp Domains repository's README, as published. We do not edit it. Read it on GitHub

RAPP Agent Builder (ChatGPT app)

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.
