## Why swap is rated Critical

Despite the empty description, the tool name 'swap' combined with the server's explicit purpose of cross-chain token swapping strongly implies this tool initiates financial transactions moving tokens between blockchains. Swapping tokens is a financial operation that commits real assets. Misuse could result in irreversible loss of funds across chains, warranting critical severity.

From the tool's own definition: "Tool name 'swap' on a server described as enabling 'cross-chain token swapping between different blockchains using 1inch Fusion+ API'"

## Use case

AI agents use swap to commit financial operations through 1inch Cross-Chain Swap MCP Server, usually the final step of a payment, billing, or trading workflow. A call moves real money.
