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.
