NSE MCP

An MCP (Model Context Protocol) server that turns National Stock Exchange of India (NSE) data into AI tools. If you use an AI assistant on your computer (Claude Desktop, Codex, Gemini CLI, Cursor, or similar), this lets that assistant answer questions about Indian stocks in plain English — "What's the live quote for RELIANCE?", "Is the market open right now?" — with real data instead of guesses.

MCP is the standard plug that lets AI apps use extra tools: you install the server once, connect it in the app's settings, and then just ask questions. Powered by jugaad-data.

Quick install

Install with one command. No Python or venv needed — the installer bundles its own runtime and prints the config entry to paste.

Windows: open PowerShell (search for "PowerShell" in the Start menu), then run:

powershell -ExecutionPolicy ByPass -c "irm https://raw.githubusercontent.com/jugaad-py/nse-mcp/main/install.ps1 | iex"

Linux / macOS: open the Terminal app, then run:

curl -LsSf https://raw.githubusercontent.com/jugaad-py/nse-mcp/main/install.sh | sh

You should see a short log ending in nse-mcp installed. If Windows asks for permission, click Yes. If something fails, copy the error text and show it to your AI assistant.

Already have Python or uv? These work too (optional):

pip install nse-mcp
# or
uv tool install nse-mcp   # on-demand alternative: uvx nse-mcp

Connect your AI app

Your AI app (the "MCP client") reads a small settings file at startup. Add the block below to that file, save it, then fully quit and reopen the app:

{
  "mcpServers": {
    "nse-mcp": {
      "command": "nse-mcp"
    }
  }
}

This is the same block the installer prints in the terminal — paste whichever is easier.

Finding the settings file: the folders start with a dot (macOS/Linux) or are hidden by default (Windows). Fastest way — open the folder directly:

• Windows: press Win + R, paste %APPDATA%\Claude, press Enter
• macOS: in Finder choose Go → Go to Folder… (Cmd+Shift+G), paste ~/Library/Application Support/Claude, press Enter
• Linux: the file is at ~/.codex/config.toml — open the ~/.codex folder (in your file manager press Ctrl+H to show hidden folders)

If the file already contains text: don't delete it. If it already has an mcpServers section, add a comma after the last entry, then paste the block after it.

Where the settings file lives, by app:

ChatGPT on the web connects only to remote servers, so use a desktop app.

What you can ask

• "Get a live quote for RELIANCE" — price, change, volume, market cap
• "Is the NSE market open right now?"
• "Which stocks gained the most today?"
• "Show me INFY's closing price for the last 6 months"
• "What's NIFTY 50's P/E compared to a year ago?"

Features

• Live prices and trades — current price, the day's high and low, volume, buy/sell depth, and futures/options contracts for a symbol (stock_quote, stock_quote_fno, trade_info, chart_data)
• Market overview — open/closed status, total turnover, biggest gainers and losers, pre-market prices, trading holidays, F&O securities, and large bulk trades (market_status, market_turnover, pre_open_market, top_stocks, holiday_list, live_fno, block_deal_session)
• Indices — live index quotes and which stocks belong to an index (all_indices, live_index, index_list)
• Option chains — the contracts available for an index, stock, or currency pair, with their set prices and dates (index_option_chain, equities_option_chain, currency_option_chain, option_chain_contract_info)
• Corporate actions — announcements, symbol metadata, registrar details (corporate_announcements, symbol_meta, reg_details)
• History — past daily prices for stocks and indices, plus index P/E, P/B, and dividend yield (stock_history, index_history, index_pe_history)

Plain-language glossary for the jargon above:

For developers

git clone https://github.com/jugaad-py/nse-mcp
cd nse-mcp
python3 -m venv .venv
.venv/bin/pip install -r requirements.txt

Run the tests (live NSE data; needs a stable network):

.venv/bin/python -m pytest tests/ -v

Run the server directly:

.venv/bin/python server.py

Troubleshooting

• Tools don't appear after the config change? Fully quit and reopen the app.
• Check the settings file is valid (quotes and commas in JSON, one = per line in TOML) and that nse-mcp starts without errors when run in a terminal.
• NSE rate-limits IPs. A transient failure just means retry the question.
