WHAT IT DOES

It is a pure read operation similar to get_orderbook, get_market, and get_candles on the same server. The blast radius of misuse is minimal—an agent could only retrieve stale or misleading pricing data, not commit financial harm directly.

From the tool's definition Tool name 'get_ticker' and description 'Current best bid / best ask / last price for a market' indicate retrieval of real-time market data with no modification or execution of trades.
