```json
{
  "jsonrpc": "2.0",

## Why start_deal is rated Critical

Starting a deal directly executes a trade on a live exchange, which constitutes a financial commitment. This falls under the Financial category as it moves or commits funds. The severity is critical because an AI agent could misuse this to initiate unintended trades with real money, potentially causing significant financial loss.

From the tool's own definition: "'Manually start a deal on an active bot immediately' — initiates a live trading deal on Binance or Hyperliquid exchanges, committing real financial transactions without waiting for a signal."

## Use case

AI agents use start_deal to commit financial operations through :GT Protocol MCP Server, usually the final step of a payment, billing, or trading workflow. A call moves real money.

## Recommended policy (PolicyLayer)
