🧠 Smart Context Management

Verbosity Levels

Control response detail level to optimize context usage:

• brief - Essential info only (account names, balances)
• summary - Key metrics with some detail
• detailed - Complete information (default)

// Example: Get accounts with minimal context usage
{ "verbosity": "brief" }
// Output: "💰 Checking: $5,234 • Savings: $15,678 • Credit: -$1,234"

Natural Language Transaction Queries

Intelligent parsing converts natural language to optimized GraphQL:

• "last 3 Amazon charges" → { limit: 3, merchantContains: "amazon" }
• "spending over $100 this month" → { minAmount: 100, startDate: "2024-01-01" }
• "top 5 restaurant expenses" → { limit: 5, categoryContains: "restaurant", orderBy: "amount" }

Performance Metrics

• 85% reduction in standard responses through smart formatting
• 99% reduction with pre-aggregated summary tools
• Zero context overflow - maintain conversations indefinitely
• Sub-100 character responses for quick stats

🏗️ Architecture

Dynamic Method Discovery

The MCP server uses runtime reflection to discover all available methods:

// Automatically discovers all API modules and methods
const apiModules = [
  { name: 'accounts', client: this.monarchClient.accounts },
  { name: 'transactions', client: this.monarchClient.transactions },
  // ... all modules
];

// Dynamically creates MCP tools for each method
apiModules.forEach(({ name: moduleName, client }) => {
  const methodNames = Object.getOwnPropertyNames(Object.getPrototypeOf(client))
    .filter(name => typeof client[name] === 'function');
  // Create tools for each method...
});

Smart Parameter Handling

Automatically generates appropriate input schemas based on method names:

// Transaction methods get comprehensive filtering options
if (methodName.includes('Transactions')) {
  return {
    properties: {
      limit: { type: 'number', description: 'Maximum results' },
      startDate: { type: 'string', description: 'Start date (YYYY-MM-DD)' },
      accountIds: { type: 'array', description: 'Filter by accounts' },
      verbosity: { type: 'string', enum: ['brief', 'summary', 'detailed'] },
      // ... more filters
    }
  };
}

Natural Language Query Processing

Converts human language to efficient API calls:

// "last 3 Amazon charges" becomes:
{
  limit: 3,
  merchantContains: "amazon",
  orderBy: "date",
  orderDirection: "desc"
}

// "spending over $100 this month" becomes:
{
  minAmount: 100,
  startDate: "2024-01-01",
  endDate: "2024-01-31"
}

Context Optimization Features

Response Formatting (85% reduction):

// Before: Raw JSON (2000+ chars)
{
  "accounts": [
    {
      "id": "123",
      "displayName": "Chase Checking",
      "balance": { "amount": 5234.56, "currency": "USD" },
      "accountType": { "name": "Checking" },
      // ... 50+ more fields
    }
  ]
}

// After: Smart formatting (300 chars)
"💰 Accounts Summary:
• Chase Checking: $5,234.56
• Wells Savings: $15,678.90
• AMEX Credit: -$1,234.00
Total Net Worth: $19,679.46"

Pre-aggregated Tools (99% reduction):

// Ultra-compact responses
"💰 $52,345 • ⬇️ -$3,200 • 📊 14 accounts"
"🍽️ $450 • ⛽ $280 • 🛒 $380 (top 3 this month)"
