Your agent acts. You set the limit.
H-Agent gives your AI agent an identity it actually holds and the ability to spend within a cap you sign, enforced on chain. Log in, set a limit, and connect it to Claude in one session. You keep control of the funds; H-Agent never holds a key.
How it works
Sign in with Google. Your identity owns the agent. No wallet app, no seed phrase, nothing to install.
Choose how much USDC your agent can spend, and how often. The cap is approved on chain by an owner-signed Spend Permission.
H-Agent mints an MPC-held wallet for your agent (the key lives in a secure enclave; we never hold it) and hands you an MCP connection string.
Paste the connection into Claude. Your agent can now check who it is, see its remaining cap, and pay, all within your limit.
Control, by design
Funds stay on your side. The agent pulls only within the cap you signed, and the cap is enforced by a smart contract, not by us behaving well.
The agent's key is held in a Trusted Execution Environment by Coinbase CDP. H-Agent has no raw key and takes no custody of your funds.
If the agent tries to spend past the cap, the transaction reverts on chain and no funds move. The limit is not a suggestion.
H-Agent is a thin authorization layer, not a payment processor. It carries your cap into the payment and rides an established facilitator to settle. Part of the H-Series under XR Utilities.
