Connect Claude to Indian stock market data

DalalOS lets you connect Claude to Indian stock market data in minutes. It is an MCP (Model Context Protocol) server that brings NSE and BSE market context into Claude, so you can research Indian stocks with AI instead of copy-pasting numbers from a dozen tabs.

This guide is written for AI-savvy Indian investors — not just developers. If you can paste one line of config into Claude, you can start analysing Indian equities with AI today.

Why connect Claude to Indian market data

Claude is excellent at reasoning, summarising and comparing — but on its own it has no direct data connection to Indian listed companies. DalalOS closes that gap. It exposes 56 current MCP capabilities over streamable HTTP, drawing from official NSE archives, BSE official interfaces and SEBI-mandated BSE-XBRL filings, covering thousands of NSE and BSE companies. Market-data research capabilities are read-only; 2 account-scoped actions only add or remove symbols from the caller's DalalOS watchlist.

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

Connect in Claude

Open Claude → Settings → Connectors → Add custom connector and paste the DalalOS MCP URL from /connect — or edit your config file directly.

Authorize once

Claude opens a sign-in popup (Google or email code) and connects automatically. No API key to create or manage.

Ask in plain English

Type a question about an Indian stock. Claude picks the right tool and answers with sourced, timestamped data.

Add the MCP config

The quickest way to connect is the point-and-click flow at /connect: sign in, then in Claude go to Settings → Connectors → Add custom connector and paste the URL shown there. Claude authorizes itself over OAuth in a popup — nothing to copy into a config file, and no API key to manage.

Prefer editing claude_desktop_config.json directly instead? Add the server below using the key dalal-os, pointing at the streamable HTTP endpoint. Save the file and restart Claude.

claude_desktop_config.json

{
  "mcpServers": {
    "dalal-os": {
      "url": "https://mcp.dalalos.in/mcp"
    }
  }
}

Either way, that is the whole setup. DalalOS is available now — there is no waitlist, and no API key for Claude specifically, since the connectors flow authorizes over OAuth the moment you connect.

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.
