Rug pull risk check. Checks mint authority, freeze authority, top holder concentration. ALWAYS run before buying.
AI agents call rug_check to retrieve information from Solana Trading MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The rug_check tool retrieves and analyzes blockchain data to assess risk factors (authority ownership and holder distribution) but does not execute trades, modify data, or commit financial transactions. It is informational and advisory in nature. The context of a trading bot does not change the tool's own function: gathering risk metrics for decision-making.
From the tool's definition Tool performs risk analysis checks: 'Checks mint authority, freeze authority, top holder concentration.' These are read-only queries of on-chain data with no side effects or state changes.
