Get the current price for an instrument.
AI agents call get_current_price to retrieve information from Deribit MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves real-time price information from the Deribit exchange. It is a read-only query that returns data without causing any modifications, deletions, or financial transactions. The blast radius of misuse is minimal—incorrect price data could lead to poor trading decisions, but the tool itself performs no irreversible actions or commitments.
From the tool's definition Tool name 'get_current_price' and description 'Get the current price for an instrument' indicate a data retrieval operation with no side effects. The action queries current market data without modifying, creating, or deleting any state.
