Return tradable pair metadata.
AI agents call get_asset_pairs 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 static metadata about cryptocurrency trading pairs (likely symbols, decimal precision, fees, etc.). It is a read-only operation with no side effects, no code execution, no financial transactions, and no data modification. The blast radius of misuse is minimal—an agent could only retrieve information already publicly available on the exchange.
