Get historical price data (OHLCV) for a token
AI agents call get_price_history to retrieve information from Opinion Trade 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 historical price information (Open, High, Low, Close, Volume) for tokens. It performs a query-only operation that does not modify state, execute code, delete data, or commit financial transactions. While the server supports trading capabilities, this specific tool is explicitly read-only data access, making it a Read category tool with low severity.
From the tool's definition Tool name 'get_price_history' and description 'Get historical price data (OHLCV) for a token' indicate data retrieval with no side effects.
