📖 Usage Examples

Swap Execution

// Parse natural language swap intent const intent = await mcpClient.call('swap.parse', { text: 'swap 1 ETH to USDC on Base', userAddress: '0x69bfD720Dd188B8BB04C4b4D24442D3c15576D10' }); // Get quote (AURA auto-selects best DEX) const quote = await mcpClient.call('swap.quote', intent.params); // Prepare transaction (check allowance, get tx data) const prepared = await mcpClient.call('swap.prepare', { quoteId: quote.quoteId, userAddress: '0x69bfD720Dd188B8BB04C4b4D24442D3c15576D10' }); // User signs transaction in browser const signedTx = await userWallet.signTransaction(prepared.transaction); // Execute swap const result = await mcpClient.call('swap.execute', { signedTransaction: signedTx });

Portfolio Analysis

// Get wallet balance across chains const balance = await mcpClient.call('portfolio.getBalance', { address: '0x69bfD720Dd188B8BB04C4b4D24442D3c15576D10', chain: 'ethereum' }); // Get DeFi positions with health factors const positions = await mcpClient.call('portfolio.getPositions', { address: '0x69bfD720Dd188B8BB04C4b4D24442D3c15576D10' });

Opportunity Scanning

// Scan for airdrop opportunities const airdrops = await mcpClient.call('ops.scanOpportunities', { kind: 'airdrop', params: { address: '0x69bfD720Dd188B8BB04C4b4D24442D3c15576D10' } }); // Scan for liquidation risks const liquidations = await mcpClient.call('ops.scanOpportunities', { kind: 'liquidation', params: { protocol: 'aave' } });

AI Strategy Automation

// Propose DCA Event-Aware Strategy const strategy = await mcpClient.call('strategy.propose', { intent: 'dca_event_aware', params: { asset: 'ETH', budgetUsd: 200, cadence: '2x/week', eventRules: { pauseOnUnlock: true, maxGasGwei: 25, boostOnDrawdownPct: 3 } }, address: '0x69bfD720Dd188B8BB04C4b4D24442D3c15576D10' }); // Backtest strategy const backtest = await mcpClient.call('strategy.backtest', { name: 'dca_event_aware', params: strategy.params, lookbackDays: 90 });
