Return ticker data (ask, bid, last, vol, etc.) for the given pairs.
AI agents call get_ticker to retrieve information from Mcp Kraken without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns publicly available ticker information (price, volume, bid/ask spreads) for cryptocurrency pairs. It performs a read-only query with no ability to modify accounts, execute trades, transfer funds, or delete data. The blast radius of misuse is minimal—an attacker can only gather market information that is typically public.
