DocStoX: Indian Stock Market MCP Server for Claude, ChatGPT and Cursor

Ask your AI assistant about any NSE or BSE stock and get answers built on real Indian market data, not the model's memory.

DocStoX is an Indian stock market MCP server, available as a Claude plugin, a ChatGPT app and an extension for Codex and Gemini CLI. It connects your assistant, over the Model Context Protocol, to NSE and BSE data for every actively traded listed company: latest and historical prices, quarterly and annual fundamentals, shareholding, FII and DII flows, F&O and index options, a stock screener, IPOs, corporate actions, filings and market news. Use it for AI stock research in India, from a single company deep dive to a Nifty and Sensex market brief.

The plugin adds five research skills on top of the server, so your assistant knows which data to pull, in what order, and how to present it with units, as-of dates and plain-English explanations.

Compare stocks

• "Compare TCS, Infosys and HCL Tech on revenue growth, margins, ROE and valuation."
• "Compare Maruti Suzuki and Tata Motors on sales growth, margins, debt and promoter holding."

Screen the market

• "Find Indian mid-caps with ROE above 20%, debt to equity below 0.5 and P/E under 30."
• "Which stocks are trading near their 52-week high with rising delivery volumes?"

Follow the market

• "Give me today's Indian market brief: Nifty, Sensex, sectors, FII and DII flows and top movers."
• "What are FIIs doing in the cash market and in index futures this week?"
• "Show the Nifty option chain with max pain, PCR and open interest build-up."
• "Which IPOs open this week, and what are GIFT Nifty, gold and crude doing?"

Your own account

• "How is my DocStoX portfolio doing today, and what news affects my holdings?"
• "Check my watchlist for results due this week."

In apps that support interactive views, stock quotes, screens and your portfolio also render as charts and tables inside the conversation.

Install the DocStoX MCP server

The server is https://mcp.docstox.com/mcp (streamable HTTP). There is nothing to clone, build or run locally. Any app that supports remote MCP servers can use it.

When you connect, a browser window opens on docstox.com so you can sign in with Google or your DocStoX email and password, then allow read-only access. A free account is created if you do not have one. Apps that cannot open a browser sign-in use a personal API key from docstox.com/mcp/keys, sent as Authorization: Bearer dox-....

Tools: Indian stock data by area

DocStoX exposes 93 read-only tools. On the Free plan, 57 return full results, 6 market-wide scans return the first rows of their results, and 30 are part of DocStoX Pro. Calling a Pro tool on Free returns a short explanation of what it would add, and that call is not counted against your allowance. Every tool, with its parameters and plan, is listed at docstox.com/mcp/tools.

Symbols are NSE tickers such as RELIANCE, TCS or HDFCBANK. Amounts are in Indian rupees; market capitalisation and flows are in rupees crore.

Skills

The plugin's skills are Markdown instructions in skills/ that guide the assistant through a research workflow. They fall back to free tools when a Pro tool is not available on your plan.

Plans and limits

The daily count resets at 00:00 UTC (05:30 IST). The read_me guide and calls to a Pro tool while on Free are never counted. Your usage is shown at docstox.com/mcp/keys. Plan details: docstox.com/pricing.

Data and privacy

• What the plugin contains: skills (Markdown instructions) and a reference to one remote server, https://mcp.docstox.com/mcp. It runs no code on your computer and stores nothing itself.
• What is sent: when your assistant uses DocStoX, it sends the tool name and its inputs (for example a stock symbol or screening conditions) to mcp.docstox.com, authenticated with your DocStoX sign-in. Your conversation, other chats, files and memory are not sent.
• What DocStoX records: usage per account (which tool, when, and whether it succeeded) to apply your plan's limits and show you your usage at https://docstox.com/mcp/keys. You can revoke a connected app there at any time.
• Read-only: every DocStoX tool reads data. The plugin cannot place trades, move money, or change your portfolio, watchlist or account.
