Indian Stock Exchange

Indian Stock Exchange MCP Server

An MCP server that gives Claude (and any MCP client) live access to the Indian market: NSE/BSE equities, fundamentals, analyst targets, IPOs, mutual funds and commodities. Ask things like:

• "Compare TCS, Infosys and Wipro on valuation, margins and momentum."
• "Give me a research note on Reliance: financials, shareholding changes, analyst targets and recent filings."
• "What's moving the market today? Any IPOs opening this week?"
• "Shortlist the best mid-cap mutual funds by 3-year return and compare the top three."

Data comes from the Indian Stock Market API.

[Demo: the compare-stocks tool returning TCS, Infosys and Wipro side by side]

Real output from the compare-stocks tool. Regenerate it with node scripts/capture-demo.mjs && scripts/render-demo.sh.

Features

• 27 tools, all read-only and annotated as such, with compact, analysis-ready output instead of raw API dumps
• One-call stock snapshot: price, ranges, valuation, profitability, growth, leverage, returns, moving-average trend, analyst consensus and peers
• Fundamentals: multi-year P&L, balance sheet, cash flow, ratios, shareholding pattern, analyst estimates and price targets
• Market: gainers/losers, most active, price shockers, 52-week highs/lows, news, IPO calendar, commodity futures
• Mutual funds: search, browse by category and return, full scheme details
• 5 prompts (analyze-stock, compare-stocks, market-briefing, dividend-and-events, mutual-fund-picks) and 3 resources (news, IPO calendar, ise://stock/{name})
• Reliable client: request timeout, retry with backoff on 429/5xx, in-memory TTL cache, in-flight de-duplication, clear error messages, and the API key is never exposed in output
• stdio transport for desktop clients and stateless Streamable HTTP for remote use

Tools

Setup

Requires Node.js 20+ and an API key from indianapi.in.

git clone <this repo> && cd Indian-Stock-Exchange-MCPcp .env.example .env        # then set ISE_API_KEYnpm installnpm run build

The key is read from the ISE_API_KEY environment variable, .env, or src/.env. Never commit it; all three files are git-ignored.

HTTP mode

npm run start:http          # http://127.0.0.1:3000/mcp  (health check: /health)

Stateless Streamable HTTP, bound to localhost by default (HOST and PORT override). It has no authentication, so put it behind a reverse proxy with auth before exposing it beyond your machine.

Development

npm test         # build + unit tests (mocked HTTP, no key needed)npm run smoke    # calls every tool against the live API (needs ISE_API_KEY)

src/  index.ts          entry point: stdio or --http  server.ts         builds the McpServer and registers everything  client.ts         API client: auth, timeout, retry, cache  tools/            stocks, fundamentals, market, funds  prompts.ts        reusable analysis prompts  resources.ts      news, IPO and per-stock resources

Notes

• Amounts are in INR; market caps are in crore.
• get-top-gainers/get-top-losers come from the API's trending list, which is BSE-listed; use get-price-shockers with exchange: NSE for NSE.
• Responses are cached for 60 seconds by default (ISE_CACHE_TTL_MS); history and fundamentals for longer.
• This server provides information, not investment advice.
