Why connect your AI tool to DalalOS
- A search gives you pages to read. DalalOS gives ChatGPT the numbers themselves, so one question can bring back a company's results, owners and peers.
- Every response carries a timestamp and its source, so you can check it.
- Ask in your own words, then follow up. No tabs, no copying into a sheet.
- Facts only: no buy or sell calls, no target prices. The data is end of day, not live.
Data comes from NSE archives, BSE official interfaces and SEBI-mandated BSE-XBRL filings, covering thousands of NSE and BSE companies, through 69 tools on an MCP server (the standard AI apps use to read outside data). 2 account actions only add or remove symbols on your DalalOS watchlist. Reading a filing can take a moment and use part of your quota.

What you need
Connect ChatGPT with the DalalOS plugin
Use the published plugin: open DalalOS in ChatGPT, select Install plugin, and sign in to DalalOS when prompted (Google, or a code we email you). You create no key and paste no URL.
Open the plugin
Use the button above, or search for DalalOS under Plugins in ChatGPT.
Install it
Select Install plugin.
Sign in
Complete the DalalOS sign-in when ChatGPT asks, then return to ChatGPT. This sign-in standard is called OAuth. There is no API key.
Ask in plain English
Start a new chat, mention DalalOS, and ask about an Indian stock. ChatGPT asks for approval before it changes your watchlist.
In plain words. A plugin is an add-on that lets ChatGPT use another service. MCP (Model Context Protocol) is the standard AI apps use to connect to outside services.
If it doesn't work
If the plugin page does not open, use manual setup below.

Manual setup if the plugin is not available to you
If the plugin page does not open, or you are outside India, add the server yourself. In ChatGPT, open Plugins, choose Create Plugin, and enter the following details. Interface labels in ChatGPT can change. ChatGPT does not use an mcpServers JSON file for this flow.
Create a plugin
In ChatGPT on the web, open Plugins and choose Create Plugin.
Add the server
Choose Server URL, enter https://mcp.dalalos.in/mcp, and select OAuth for authentication.
Authorize
Create the plugin, complete the DalalOS sign-in window, then return to ChatGPT.
Test it
Start a new ordinary chat, select the plugin, and make a research request.
For a first test, ask: “Use DalalOS to fetch the latest available quote and company profile for Reliance Industries. Tell me which DalalOS tools you called, the source of the data, and its freshness date. Do not use web search.”
A successful response names the tools it called and includes source and freshness information. Prices are end-of-day, and DalalOS is not a real-time exchange feed. If ChatGPT rejects the server URL, confirm that it matches https://mcp.dalalos.in/mcp, including the /mcp path.

FAQ
Common questions
- Is the data real-time?
- No. Prices are end-of-day, financials arrive within the filing cycle, and shareholding updates quarterly. Each response carries a timestamp and its source. DalalOS is not a real-time exchange feed.
- Does it give buy or sell recommendations?
- No. DalalOS returns raw data and mechanically-computed ratios only. Your agent reasons over the numbers, and you make your own investment decisions.
- How is this different from asking the model directly?
- Without a data connection, a model answers from memory, and memory can be stale or wrong for a given Indian ticker. Connected to DalalOS, the agent fetches current, sourced figures and shows where each came from.
- Do I need an API key to connect these tools?
- No. Use OAuth when the client supports it. The easiest way to connect ChatGPT is the published DalalOS plugin (https://chatgpt.com/plugins/plugin_asdk_app_6aded6de90f081918717da5227322e16): select Install plugin and sign in. If the plugin is not available to you, connect ChatGPT on the web through Plugins → Create Plugin: select Server URL, enter https://mcp.dalalos.in/mcp, choose OAuth, then complete the DalalOS sign-in. Use an API key only for a client that cannot use OAuth or requires a Bearer header.
- How do I know ChatGPT is using DalalOS?
- Ask ChatGPT to name the DalalOS tools it called and to include the source and freshness timestamp. A working connection returns those details. Prices are end-of-day; DalalOS is not a real-time exchange feed.
