MarketPing MCP server

Indian stock-market research for AI assistants: NSE/BSE corporate filings read by AI with the measured price reaction after each one, fundamentals for 5,000+ companies, page-cited reads of annual reports and earnings calls, a 108-metric screener, the IPO pipeline, FPI flows, the results calendar and the daily market briefing.

• Endpoint: https://mcp.marketping.in/mcp — remote, Streamable HTTP, JSON-RPC 2.0, MCP protocol 2025-06-18
• Auth: none for 20 of the 24 tools. No API key, no sign-up. Four account tools use OAuth 2.1.
• Writes: exactly one tool (watchlist_add), annotated readOnlyHint: false. Everything else is read-only.
• Advice: none. MarketPing publishes what companies filed and what the stock did next — no buy/sell calls, no price targets, no ratings, no grey-market premium.
• Product page: https://marketping.in/mcp · Operator: MarketPing, India · Contact: support@marketping.in

This repository is the server's public contract: the exact tool catalogue the server returns from tools/list (tools.json), a registry manifest (server.json), and a small open-source stdio bridge for clients that cannot speak Streamable HTTP directly. The server itself runs on MarketPing's infrastructure; its handlers are thin read-only wrappers over the same code paths that serve marketping.in.

ChatGPT (Developer mode / Apps) — add MCP server: same URL.

Cursor / VS Code / Windsurf (mcp.json):

{
  "mcpServers": {
    "marketping": { "url": "https://mcp.marketping.in/mcp" }
  }
}

Clients that only speak stdio — bridge to the same endpoint with mcp-remote:

{
  "mcpServers": {
    "marketping": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.marketping.in/mcp"]
    }
  }
}

That runs the published mcp-remote bridge against the endpoint above and nothing else. It stores no credentials of its own; mcp-remote keeps OAuth tokens in its standard location (~/.mcp-auth) only if you link an account.

bin/marketping-mcp.js in this repo does the same thing as a named wrapper. It is not published to npm, so npx -y @marketping/mcp will not resolve — run it from a clone, or just use the mcp-remote form above.

The 24 tools

Exact schemas and annotations: tools.json (the live tools/list response, captured 19 Sep 2026). Every description ends with the no-advice line — that is part of the contract the consuming model reads.

Data handling

• A tool call sends only the tool's arguments (a company name, a query, a date range) to mcp.marketping.in over HTTPS. Nothing else leaves the client; the bridge adds no telemetry.
• Anonymous calls are metered by caller class: a direct end-user IP gets its own daily budget (200 tool calls per IST day, the same as the Free plan); hosted assistants (claude.ai, ChatGPT) call from vendor egress ranges and share a bounded pool. Quota exhaustion is a normal tool result with a message, never an auth error.
• Linking a MarketPing account (OAuth 2.1; discovery at https://mcp.marketping.in/.well-known/oauth-authorization-server and /.well-known/oauth-protected-resource) unlocks the four account tools and the account's plan budget (Investor 1,000 / Trader 2,000 calls per day). Tokens are issued by MarketPing's own authorization server and can be revoked from the account's settings.
• Every result carries a marketping.in URL so the assistant can cite the page. Document text comes only from read_pages, page-anchored, so quotes are checkable.
• No tool fetches arbitrary URLs, runs code, or reads anything outside MarketPing's database.

Verify it yourself

curl -s -X POST https://mcp.marketping.in/mcp \
  -H "Content-Type: application/json" -H "Accept: application/json, text/event-stream" \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-06-18","capabilities":{},"clientInfo":{"name":"curl","version":"1"}}}'

curl -s -X POST https://mcp.marketping.in/mcp \
  -H "Content-Type: application/json" -H "Accept: application/json, text/event-stream" \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/list","params":{}}'

The second response is tools.json.

About MarketPing

MarketPing is an Indian stock-market research platform built around one idea: every NSE and BSE corporate filing, read by AI the moment it is published, delivered to WhatsApp within a minute, and followed by the measured price reaction — what the stock actually did 5 minutes to 3 months later. 500,000+ filings decoded, 1.9 million reactions measured, 5,000+ companies. It publishes no buy/sell calls, no price targets and no ratings.

What the same data looks like on the site (every MCP result links back to one of these):

• Announcements feed — every filing with its AI read and reaction; e.g. a contract-win filing or a buyback
• Company pages — filings, financials, concall reads and the results date; e.g. Reliance Industries, HDFC Bank
• Discover — stocks by catalyst: contract wins, QIPs, pledges released, demergers, CEO exits, splits and bonuses
• Screener — 108 fundamentals metrics with custom formulas, and Stacks, lists composed from screens, indices and watchlists
• IPO tracker — 1,150+ issues, live subscription by category, listing performance, banker league tables, deliberately no grey-market premium
• Daily market briefing and its archive, FPI flows, the results calendar
• Reaction Lab — how each category of announcement has moved stocks, in aggregate
• Glossary (60 terms, e.g. earnings call, record date vs ex-date, QIP), 33 free calculators, comparisons with Screener.in, Tickertape, Trendlyne and others
• Nexa AI — ask anything about a company and get page-cited answers
• Features · Pricing — free for 5 companies with WhatsApp delivery; Investor ₹199/month (30), Trader ₹599/month (100)
• llms.txt — the answer blocks MarketPing publishes for AI assistants
