Overview

AI-generated overview

Lets an assistant check, price, and register domain names in bulk, paying per request.

What it does
The registry description says it checks and prices up to 20 domain names at once and lets agents register them, paying per request. The README describes a broader RAPP Agent Builder app whose tools supply an agent template, check a finished agent file against the rules, search the public RAPP Agent Registry, return a registry agent's source, run an agent in the chat, and explain how to run it locally. The MCP endpoint is a stateless streamable HTTP service returning JSON.
When to use it
Useful when an assistant needs bulk domain availability and pricing checks, or when it should register domains on the user's behalf. The agent-builder tools fit workflows that generate, validate, or look up RAPP agents from the public registry.
Requirements
A remote streamable HTTP endpoint; no packages, environment variables, or headers are declared. The manifest declares no authentication. Network access to the endpoint is required.
Before you install
The description states that registration is paid per request, so an assistant could spend money. Registration writes and changes data. The manifest declares no authentication, so anyone reaching the endpoint may be able to use it. The README says the server reads a public registry and points at a public installer.

README

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.
