get_options_chain
AI agents call get_options_chain to retrieve information from Digital Oracle MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Options chain data is typically static market information (strike prices, contract details, bid-ask spreads) retrieved from financial data providers. No description is provided, which slightly lowers confidence, but the tool name pattern and server context (other price/data retrieval tools) indicate this fetches rather than modifies financial data.
From the tool's definition Tool name 'get_options_chain' indicates data retrieval. Server context confirms this is a financial market data tool alongside other read-only tools like get_crypto_prices, get_price_history, and get_polymarket_events.
