Swap tokens or MON on Uniswap V2 on Monad testnet
AI agents use swap to commit financial operations through Monad MCP Server — usually the final step of a payment, billing, or trading workflow. A call moves real money.
Swapping tokens on a DEX is a financial transaction that moves assets between parties. While this is on a testnet (reducing real-world financial impact), the tool performs asset exchange operations. The severity is high because an AI agent could misuse this to swap tokens at unfavorable rates or drain a wallet's token holdings. Testnet context lowers severity slightly but the operation is inherently financial.
