Connects Claude to Yault's crypto vault API so agents can check balances, deposit funds, redeem shares, and transfer allocations between accounts. Every spend goes through a policy engine with per-transaction limits, rolling budgets, address allowlists, and time windows. Risky actions escalate to a human review queue instead of auto-approving. You configure it with your own Yault API key, so the agent operates your vault under your rules. Useful when you want an agent to handle routine crypto operations but need guardrails and veto power. The underlying SDK also exposes EIP-712 commitment builders and agent identity derivation if you're building custom workflows.
