Rar Agent Finder tools (5, 1 write)

write = sends, deletes, buys or posts
  • find_agentsFree

    Searches the public agent registry (about 1,700 single-file agents) for agents that already do what the user wants, for example when they ask 'is there an AI tool for...' or want a ready-made automation instead of building one. Use it before building from scratch, or when the user asks whether an agent exists for a task.

  • get_agent_codeFree

    Returns the full source of one agent from the registry, by its name (e.g. @bill/neuron_agent), so it can be read or adapted.

  • how_to_run_agentwrite actionFree

    Optional, for later: how to keep an agent running on the user's own computer with the free Brainstem. Only offer this after the user has used the agent in the chat and wants to keep it.

  • 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.

  • use_agent_hereFree

    Use this right after an agent passes check_agent, or whenever the user wants to try an agent. Returns a short Python runner so you can run the agent in this chat with your own Python tool on the user's own data (pasted text, an uploaded spreadsheet, a list). Nothing to install. If Python is unavailable, apply the agent's logic yourself by reading its code. Ask the user for their real data, run the agent, and show the result in plain words.

What the publisher says

From the Rar Agent Finder 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.
