Get detailed information about a market
AI agents call ig_get_market_details to retrieve information from IG Trading MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves market information without side effects. Even in the context of a trading platform, querying market details does not create positions, modify accounts, execute orders, or move money. It is a straightforward data query operation with minimal risk if misused by an AI agent—an agent could retrieve irrelevant market data, but no financial or operational harm would result.
From the tool's definition Tool name 'ig_get_market_details' and description 'Get detailed information about a market' indicate data retrieval with no modification or execution of trades.
