What the publisher says

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

Reins

Let an AI agent trade without giving it the power to lose everything.

npx @r2rlabs/reins init      # adds a paper-trading Reins server to .mcp.json

See it at work: an AI agent trading Hyperliquid on paper, run 2.

The source is on GitHub: R2Rlabs/reins. Every limit in this README is a function you can read.

What Reins is

outside the model: position size, leverage, daily loss, which markets it may trade, and a stop-loss on every position. No prompt, clever reasoning or mistake gets around them.

  • Limits the agent can't argue with. Every order passes checks that live

gave — including the orders it was refused, the times it chose to wait, and what the exchange did without it. You can compare what the agent said with what actually happened.

  • A record you can check. Every decision is logged with the reason the agent

realistic fills and fees, using the same tools and limits as live trading.

  • Somewhere to rehearse. Paper trading on live Hyperliquid prices with

trades through an API wallet, which can place orders but cannot withdraw.

  • Non-custodial. Your money stays in your own Hyperliquid account. Reins
  • Paid for openly. A small builder fee (2 bp) on live orders, shown up front.

What Reins is not

won't make an agent profitable. The demo agent is a test drive, not the product.

  • Not a trading bot or a strategy. Reins doesn't decide what to trade and

orders; Hyperliquid does that.

  • Not an exchange, broker or custodian. It holds no funds and matches no

make bad trades good, and stops can slip in fast markets.

  • Not a promise against losses. Limits cap how much can go wrong. They don't

ours: every action is on the record.

  • Not financial advice.
  • Not something you have to take on trust. Not the agent's word, and not

Principles

  1. Limits live outside the model.
  2. The record outranks the reasoning.
  3. Paper before real money.
  4. Your keys, your funds.

Why this exists

Several open-source Hyperliquid MCP servers already exist. They are thin API wrappers: you hand them a private key and hope the model behaves. The gap is everything around that — the limits, the sandbox, the audit trail. That is what this repo is.

Status

Early, but real. 391 tests, no network calls in any of them.

Shortened. The full README is on GitHub.

Nothing above is checked by us. What we check is on the safety report.
