Claim all accrued KSKD rewards for the MCP wallet from the RewardsController.
AI agents use claimRewards to commit financial operations through Kaskad Protocol MCP Server — usually the final step of a payment, billing, or trading workflow. A call moves real money.
Claiming rewards triggers an on-chain financial transaction that moves KSKD tokens to the wallet. This constitutes a financial operation (asset transfer) within a DeFi protocol. Misuse could drain accrued rewards prematurely or be exploited in a reward-claiming attack. Severity is high given it operates autonomously on a DeFi protocol with real token value.
