Overview

AI-generated overview

Turns an idea or meeting transcript into a working single-file AI agent, checks it against rules, and runs it in chat.

What it does: This remote MCP server supports building a single-file RAPP agent from an idea or a meeting transcript. It supplies the official agent template and its rules, validates a finished agent file against those rules, and searches the public RAPP Agent Registry, returning a registry agent's source code. It also provides a runner so the assistant can execute the agent in the chat on the user's data, plus optional instructions for running the agent locally.
When to use it: Use it when you want to draft, validate, or reuse a small single-file agent without writing the scaffolding yourself, or when you want to find an existing agent in the public registry and run it in the conversation. It is aimed at quick agent prototyping from a prompt or transcript rather than large multi-service systems.
Requirements: A remote streamable HTTP endpoint; no packages, environment variables, or headers are declared, and no authentication is declared. The assistant must be able to reach the endpoint over the network. Running a generated agent locally is optional and is described by the server's own instructions.

Before you install

The server is stateless and remote, so prompts, transcripts, and agent files you submit are sent to a third-party endpoint. The runner tool executes a generated agent on your data inside the chat, so review what the agent does before pointing it at sensitive content. Registry agents returned by the lookup tools are third-party code; inspect them before running.
