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 the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
