DocStoX

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.

• "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."

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.
