Connect Claude to Indian stock market data

Why connect Claude to Indian market data

Claude is excellent at reasoning, summarising and comparing — but on its own it has no live window into Indian listed companies. DalalOS closes that gap. It exposes 20+ read-only tools over streamable HTTP, drawing from official NSE archives, BSE official APIs and SEBI BSE-XBRL filings, covering roughly 5,000 NSE and BSE companies.

Once connected, you can ask Claude to pull end-of-day quotes, explore fundamentals, compare companies, and read shareholding trends — and Claude does the reasoning on top of real, sourced numbers.

How it works

Add the server

Paste the DalalOS MCP config into your Claude client and restart it.

Ask in plain English

Type a question about an Indian stock. Claude picks the right tool automatically.

Get sourced data

Claude answers using official, timestamped data — no scraping, no verdicts.

Add the MCP config

Open your Claude client config (commonly claude_desktop_config.json) and add the server below. The server key is dalal-os, pointing at the streamable HTTP endpoint. Save the file and restart Claude.

claude_desktop_config.json

{
  "mcpServers": {
    "dalal-os": {
      "url": "https://indianstockdatamcp.duckdns.org/mcp"
    }
  }
}

That is the whole setup. There is no API key juggling in this guide — join the waitlist to receive your access details and endpoint when your invite opens.

FAQ

Common questions

How do I connect Claude to Indian stock market data?

Add the DalalOS MCP server to your Claude client config (claude_desktop_config.json) using the server key "dalal-os" and the streamable HTTP endpoint, then restart Claude. Once connected, Claude can call the read-only tools and answer questions about NSE/BSE stocks in plain English.

Does this give Claude real-time prices?

No. Data is end-of-day (after market close), plus financials within the filing cycle and shareholding each quarter. Every response is timestamped with its source so you know how current it is. It is not a real-time exchange feed.

Is the output investment advice?

No. DalalOS returns raw data and mechanically-computed ratios only — no recommendations, target prices or buy/sell calls. Claude reasons over the numbers; you make investment decisions independently.

Does it work with Claude Desktop and other Claude clients?

Any Claude client that supports MCP servers over streamable HTTP can connect. The same endpoint also works with other MCP clients such as Cursor and ChatGPT-style agents.
