Mock Mode

The server ships with a full mock data layer. Set MOCK_MODE=true in your environment and every tool returns realistic hardcoded data using real Indian stocks (RELIANCE, TCS, INFY, HDFCBANK, ICICIBANK, WIPRO, BAJFINANCE) and real mutual fund schemes. No Groww account needed. No API calls made.

MOCK_MODE=true node dist/index.js

---

WARNING

This software can place real trades and move real money.

A poorly worded prompt can trigger a market order. A misunderstood confirmation can invest your savings in the wrong fund. The mock mode exists specifically so you don't learn this the hard way.

Use MOCK_MODE=true until you are absolutely certain. Test with small amounts first. The authors of this project accept zero responsibility for financial losses incurred through use of this tool.
