## Testing Guide
### 1. Start the MCP Inspector
```bash
npm run inspector
```
### 2. Authenticate First
- Run: `start_authentication`
- Open the login URL in browser
- Get `tokenId` from redirect
- Run: `complete_authentication` with `tokenId`
### 3. Test Place Order
```json
{
"dhanClientId": "YOUR_CLIENT_ID",
"correlationId": "test_order_001",
"transactionType": "BUY",
"exchangeSegment": "NSE_EQ",
"productType": "INTRADAY",
"orderType": "LIMIT",
"validity": "DAY",
"securityId": "11536",
"quantity": 1,
"price": 1500
}
```
### 4. Test Get Order Book
Simply call `get_order_book` with no parameters - it returns all orders.
### 5. Test Super Order
```json
{
"dhanClientId": "YOUR_CLIENT_ID",
"correlationId": "super_order_001",
"transactionType": "BUY",
"exchangeSegment": "NSE_EQ",
"productType": "INTRADAY",
"orderType": "LIMIT",
"securityId": "11536",
"quantity": 1,
"price": 1500,
"targetPrice": 1600,
"stopLossPrice": 1450,
"trailingJump": 10
}
```
## Architecture Decisions
### 1. Separation of Concerns
- **types.ts**: Data structures only
- **authentication.ts**: API logic (requests/responses)
- **index.ts**: MCP server & tool registration
- **config.ts**: Environment configuration
### 2. Error Handling Strategy
All functions:
- Validate access token before making requests
- Catch both axios errors and unexpected errors
- Return descriptive error messages with HTTP status
- Log all operations to stderr for debugging
### 3. Request/Response Pattern
- All functions follow consistent axios request pattern
- Headers always include: `Content-Type: application/json`, `access-token`
- Responses parsed as TypeScript interfaces
- All data returned as JSON via MCP content
### 4. Type Safety Approach
- Request and response types defined for each endpoint
- Full type casting in tool handlers
- No `any` types used
- All parameters properly validated
## Next Steps (Optional Enhancements)
1. **Instrument Search**: Add tool to search instruments by symbol
2. **Market Data**: Add quotes, OHLC, and historical data tools
3. **Holdings**: Add tool to retrieve current holdings
4. **Positions**: Add intraday positions tool
5. **Portfolio**: Add portfolio analytics tools
6. **Alerts**: Add price alert management
7. **Database Integration**: Persist order history
8. **Token Refresh**: Implement automatic token refresh
9. **Webhook Support**: Handle DhanHQ webhooks for order updates
10. **React UI**: Build web interface for order management
