+## Privy Agent CLI
+
+[Privy Agent CLI](https://docs.privy.io/recipes/agent-integrations/agent-cli) gives agents a CLI-first way to create, fund, and manage wallets with no integration code. It pairs with the [Agent Sandbox](https://agents.privy.io/) where users track agent spending, manage funds, and revoke access.
+
+The agent never holds the wallet private key—each CLI session generates a P-256 keypair used to sign authorization payloads.
