DalalOS

I built an MCP server/connector to fetch financial data for all listed stocks on NSE and BSE. It can pull things like QoQ profit/revenue growth for any stock, price trends, promoter holdings, institutional investors, new company declarations, and more. I’ve also built 25 tools within the MCP to support different financial-data use cases. Today, if you ask Claude for personal finance or stock-related advice, it usually relies on web searches or stale training data. The reasoning might still be sound, but the underlying data sources can be outdated or unreliable. With this MCP/connector, Claude can use a more reliable source of truth for financial data, which should help: Improve the quality of results Reduce the token usage spent on web searches

FAQ

Questions, answered

Is this investment advice?

No. DalalOS serves raw data and mechanically-computed ratios only — no recommendations, target prices or buy/sell calls. You and your AI draw the conclusions, and you make every investment decision independently.

Where does the data come from?

Official, regulatory sources only: NSE archives, BSE official APIs and SEBI-mandated BSE-XBRL filings. No scraped vendor data.

How fresh is the data?

Prices are end-of-day (after market close), financials land within the filing cycle, and shareholding updates each quarter. Every response is timestamped with its source, so you always know how current a number is. It is not a real-time exchange feed.

Which AI assistants work with DalalOS?

Anything that speaks MCP — Claude, ChatGPT-style agents, Cursor, Perplexity and other AI agents. You connect once and ask questions in plain English.

Do I need to be a developer to use it?

No. DalalOS is built for AI-savvy Indian investors, not just developers. If you can paste one line of config into your AI client, you can connect it and start researching Indian stocks with AI.
