Perplexity

Run deep wallet profiling inside Claude Desktop

The `profiler_current_balance` tool pulls live token balances directly into your Claude Desktop chat window. You don't need to open three different block explorers or copy-paste long hex strings back and forth. Just paste a wallet address and let your agent map its holdings, historical snapshots, and associated profiles using `profiler_historical_balances` and `profiler_labels`. This local integration lets you cross-reference on-chain identities without leaking your workspace context. By running this MCP Server locally through your config file, you can inspect suspicious counterparties via `profiler_counterparties` and trace connected entities using `profiler_related_wallets` directly from your desktop terminal.

Track smart money flow intelligence with Claude Desktop

The `smart_money_netflow` tool identifies where institutional capital is moving across major EVM chains in real time. Your agent queries this endpoint to pinpoint which tokens are experiencing heavy accumulation or sudden distribution. Instead of manual sorting, Claude scans the incoming JSON arrays and flags anomalous volume spikes instantly. Combine this flow data with `smart_money_holdings` to see exactly what smart money wallets hold right now. You can also pull recent decentralized exchange transactions using `smart_money_dex_trades` to catch early momentum before it hits retail dashboards, keeping your research pipeline completely inside your local chat interface.

Analyze prediction markets and perpetual leaderboards

The `perp_leaderboard` tool reveals the most profitable Hyperliquid traders, exposing their open positions and execution strategies. Your agent processes these rankings to help you copy-trade or monitor top-tier market makers. You can inspect specific traders using `profiler_perp_positions` to dissect their leverage and risk profiles. For event-driven plays, use `prediction_market_screener` and `prediction_orderbook` to extract real-time bid-ask depth on major political or crypto betting markets. Claude handles the heavy math, calculating win rates and aggregate PnL via `prediction_pnl_by_address` so you can spot mispriced contracts before the crowd reacts.
