## 📦 **Installation**

```bash
npm install monarchmoney
```

## 🏃 **Quick Start**

### **Standard Usage**
```typescript
import { MonarchClient } from 'monarchmoney'

const client = new MonarchClient({
  baseURL: 'https://api.monarchmoney.com',
  timeout: 30000
})

// Login with credentials and MFA
await client.login({
  email: 'your-email@example.com',
  password: 'your-password',
  mfaSecretKey: 'your-mfa-secret' // Optional TOTP secret
})

// Get accounts with different verbosity levels
const accounts = await client.accounts.getAll({ verbosity: 'light' })
const transactions = await client.transactions.getTransactions({
  limit: 10,
  verbosity: 'ultra-light'
})
```

### **AI Assistant Integration**
```typescript
import { MonarchClient, ResponseFormatter } from 'monarchmoney'

const client = new MonarchClient(/* config */)
await client.login(/* credentials */)

// Get ultra-compact responses perfect for AI context
const accounts = await client.accounts.getAll({ verbosity: 'ultra-light' })
// Returns: "💰 12 accounts, Total: $145,678"

// Or format existing data for AI consumption
const formatted = ResponseFormatter.formatAccounts(rawAccounts, 'ultra-light')
const quickStats = ResponseFormatter.formatQuickStats(accounts, recentTransactions)
// Returns: "💰 $52,345 • ⬇️ -$3,200 • 📊 14 accounts"
```

## 🎯 **Context Optimization Features**

### **Verbosity Levels**
Control response detail to optimize AI context usage:

| Level | Use Case | Characters/Item | Example |
|-------|----------|-----------------|---------|
| `ultra-light` | Quick overviews | ~60 chars | `💰 5 accounts, Total: $23,456` |
| `light` | Moderate detail | ~180 chars | Account names + balances + institutions |
| `standard` | Full analysis | ~800 chars | Complete account details + metadata |

### **Smart Query Selection**
```typescript
import { getQueryForVerbosity } from 'monarchmoney'

// Automatically select optimal GraphQL query
const query = getQueryForVerbosity('accounts', 'ultra-light')
// Returns optimized query with minimal fields
```

### **Response Formatters**
```typescript
import { ResponseFormatter } from 'monarchmoney'

// Ultra-compact account summary
const summary = ResponseFormatter.formatAccounts(accounts, 'ultra-light')
// "💰 12 accounts, Total: $145,678"

// Quick financial overview
const overview = ResponseFormatter.formatQuickStats(accounts, transactions)
// "💰 $52,345 • ⬇️ -$3,200 • 📊 14 accounts"

// Spending by category
const spending = ResponseFormatter.formatSpendingSummary(transactions, 5)
// "🍽️ $450 • ⛽ $280 • 🛒 $380 (top 3 this month)"
```

## 📚 **API Documentation**

### **Accounts API** (15+ methods)
```typescript
// Get accounts with verbosity control
const accounts = await client.accounts.getAll({
  includeHidden: false,
  verbosity: 'light'
})

// Get specific account details
const account = await client.accounts.getById('account-id')

// Get balance history
const history = await client.accounts.getBalanceHistory('account-id')
```

### **Transactions API** (25+ methods)
```typescript
// Get transactions with smart filtering
const transactions = await client.transactions.getTransactions({
  limit: 50,
  startDate: '2024-01-01',
  endDate: '2024-01-31',
  verbosity: 'ultra-light'
})

// Smart search with natural language
const amazonCharges = await client.transactions.smartQuery({
  query: "last 5 Amazon charges over $50"
})
```

### **Budgets API** (12+ methods)
```typescript
// Get budget data
const budgets = await client.budgets.getBudgets({
  startDate: '2024-01-01',
  endDate: '2024-01-31'
})

// Get budget performance
const performance = await client.budgets.getBudgetSummary()
```

### **Categories & Insights APIs**
```typescript
// Get all categories
const categories = await client.categories.getCategories()

// Get financial insights
const insights = await client.insights.getNetWorthHistory()

// Get cashflow analysis

  retries: 3,
  retryDelay: 1000,
  rateLimit: {
    requestsPerSecond: 10,
    burstSize: 20
  },
  cache: {
    enabled: true,
    ttl: 300000, // 5 minutes
    maxSize: 1000
  }
})
```

await client.interactiveLogin()
```

## 🎨 **MCP Integration Example**

Perfect for Claude Desktop and other Model Context Protocol integrations:

```typescript
// MCP Tool Implementation
async function getAccountsSummary(verbosity = 'ultra-light') {
  const accounts = await client.accounts.getAll({ verbosity })

  // Returns context-optimized response:
  // "💰 12 accounts, Total: $145,678"
  return accounts
}

async function smartTransactionSearch(query: string) {
  const result = await client.transactions.smartQuery({ query })

  // Natural language to optimized GraphQL:
  // "last 3 Amazon charges" → targeted GraphQL query
  return ResponseFormatter.formatTransactions(result.transactions, 'light', query)
}
```
