Frequently asked questions
How can I track where Smart Money is moving capital?
Use the smart_money_netflow tool to see net capital flows (inflows vs outflows) for tokens, or smart_money_holdings to see aggregated balances held by these sophisticated entities.
Can I identify the behavior or identity of a specific wallet?
Yes, use profiler_labels or profiler_premium_labels to retrieve behavioral tags (like 'Smart Money', 'Heavy DEX User', or ENS names) associated with any blockchain address.
How do I analyze the performance of a specific address?
Use profiler_pnl_summary to get an aggregate view of profits and losses, or profiler_pnl for a detailed breakdown of performance for a specific address and token pair.
How does Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
