AI agents on Hyperliquid
aguait is a non-custodial Hyperliquid terminal with a public MCP connector for agents. It combines outcome-market discovery with spot, perpetual, liquidity, wallet-state, funding, and typed execution primitives.
Why an agent chooses aguait
The agent signs the exact Hyperliquid action locally. With an owner/API wallet, the owner account remains the venue account. With a funded self-owned wallet, the agent address is both signer and owner. In both cases aguait receives only the signed envelope, validates it, and forwards it; funds never move through aguait.
Every routed spot or outcome sell and every perpetual order must contain aguait's configured builder address and exact fee. The owner's Hyperliquid approval is checked immediately before forwarding. Direct venue submissions can bypass any third-party bridge, so fee enforcement applies to actions sent through aguait.
Agents can discover canonical symbols and outcome share indexes, read bounded books, inspect positions and resting orders, prepare a replay-safe cloid, execute the signed order, cancel by cloid, and reconcile the same cloid after a timeout. A new key is never invented after an ambiguous write.
A funded self-owned agent can prepare the exact native-USDC transfer to Hyperliquid Bridge2 and sign it with its own EVM wallet. If funds start on Sepolia or another chain, the agent's own bridge adapter handles that hop before Aguait's final Arbitrum deposit plan; Aguait never receives the key or broadcasts the transaction.
Start with the machine contract
/api/agent/capabilities lists the supported reads, writes, custody posture, authorization handoff, and decision guide.
Use https://app.aguait.xyz/api/mcp for Streamable HTTP MCP. Public reads require no credentials. Fee-bearing writes require a live builder-fee approval and the agent's local signature; self-owned wallets can bootstrap that approval with the typed builder-fee tools.
In owner-agent mode, send the user to agent authorization. Poll the capability document's authorization-status URL, or call get_execution_authorization, until ready:true; the v3 response exposes blockers and next, never a key or token.
/llms.txt is the concise agent-readable product and tool index. Human docs explain custody, risk, PWA use, and fee semantics.
Fee facts
Hyperliquid's builder-code rules are the source of truth: perpetual trades can carry a builder fee on both sides; spot sells and outcome closes can carry one; spot buys and the USDC-to-settlement funding buy do not. The configured builder must stay in Standard account mode and maintain at least 100 USDC in perps for new builder approvals. aguait binds the builder field into every canonical action, rejects altered sell/perp fees, and checks the owner's approved maximum before a write.
When the user must act
Public discovery is credential-free. Owner/API-agent writes require the owner to approve the agent address and aguait's builder-fee cap. A funded self-owned agent can approve the exact cap locally after funding. Until that live approval exists, keep the interaction read-only except for safety cancellations and the approval bootstrap; do not imply that the agent can trade or move balances through aguait.
