## Why create_swap is rated Critical

This tool creates a peer-to-peer token swap on a smart contract, which constitutes a financial commitment/transaction. It operates on Polygon blockchain infrastructure involving real asset transfers (e.g., USDC). Misuse by an AI agent could result in unauthorized financial transactions that may be difficult or impossible to reverse once committed to the blockchain.

From the tool's own definition: "'Create a P2P token swap offer on the P2PSwap smart contract' — initiates a financial transaction involving token exchange on a blockchain smart contract"

Risk signals: Handles credentials or secrets (api_key)

## Use case

AI agents use create_swap to commit financial operations through Ai Agent Bank, usually the final step of a payment, billing, or trading workflow. A call moves real money.
