An AI agent can read every market RXN shows and trade from your Hyperliquid account. It does so inside limits you sign: how much it may lose, how much it may hold, which markets, and for how long. Its key trades and can never withdraw.
The limits you sign
- Loss limit. The most it may lose from when you sign: fees, funding, and what each position would lose at its stop. A win after a loss refills nothing.
- Size. What it holds stays within 20 times the loss limit, however tight its stops. A $50 loss limit allows $1,000 of positions.
- Leverage and markets. The highest leverage and the markets it may trade, never above a market’s own maximum.
- Time. Up to 30 days. Then you sign again.
How it connects
RXN’s server runs on your own computer, next to your agent, and speaks MCP. Claude Code, Claude Desktop or your own bot can call it, over stdio or HTTP, and every answer is JSON. Then you ask in plain words, for example: “Which markets pay the most funding to shorts?”
To let it trade, you approve a key for the agent on Hyperliquid’s API page. It is the agent’s own key, not the RXN key in your browser, and Hyperliquid lets it trade but never withdraw.
Where it stands today
The limits above are what RXN’s server holds an agent to, as rxn.gg/docs lists them from the code.
An agent can lose money within its limits, as any trader can. Perpetual futures carry risk of loss.
