Quantustik MCP server — S&P 500 market data

Quantustik is a market data service for the S&P 500 — prices, fundamentals, SEC filings, insider and Congress trades, macro indicators and market conditions — for investors and AI agents, through a dashboard, a REST API and an MCP server.

The hosted MCP server at https://quantustik.com/mcp (streamable-HTTP) needs no API key. It serves nine tools:

Tool	What it returns
get_fear_greed	CNN Fear & Greed index (0-100)
get_earnings_calendar	Next and last earnings dates for a ticker
get_insider_pulse	SEC Form 4 insider activity, per ticker or an S&P 500 screener
get_filings_digest	SEC 8-K event digest, per ticker or a recent site-wide feed
get_filing_language_diff	What changed in the prose between a ticker's two most recent 10-K or 10-Q filings
get_institutional_activity	13F institutional ownership changes and SC 13D/G activist filings
get_congress_trades	STOCK Act disclosures from the House Clerk and Senate eFD
list_capabilities	Discover all tools and resources
get_started	Onboarding: per-tier quotas and how a free API key raises them

Every value carries its source and as-of date. Quantustik publishes measured data only, with no predictions and no recommendations.

Educational research only — not financial advice. Nothing here is a recommendation to buy or sell any security.

Connect

Clients that support remote streamable-HTTP servers can point straight at https://quantustik.com/mcp. Clients that only support local stdio servers (Claude Desktop, Cursor, Windsurf and others) can use this package, described below. Anonymous use is allowed under a per-IP hourly quota; a free key from quantustik.com/developers raises it.

What this package is

A thin stdio proxy to Quantustik's hosted MCP server. It lets MCP clients that only support local stdio servers (Claude Desktop, Cursor, Windsurf, and others) reach the live, keyless, streamable-HTTP endpoint at https://quantustik.com/mcp.

This package does not implement an MCP server itself, run any model locally, or cache any data. It is a small wrapper around mcp-remote pointed at our hosted endpoint. Every tool call is forwarded live to quantustik.com and answered from the same data and quota system as the hosted endpoint.

If your MCP client supports remote streamable-HTTP servers directly, you don't need this package at all — just point it at https://quantustik.com/mcp. This wrapper exists only for stdio-only clients.

The full tool catalog lives at quantustik.com/developers.

Usage

Claude Desktop / Cursor / Windsurf

Add to your MCP client config (e.g. claude_desktop_config.json):

{
  "mcpServers": {
    "quantustik": {
      "command": "npx",
      "args": ["-y", "@quantustik/mcp-server"]
    }
  }
}

Command line

npx -y @quantustik/mcp-server

This starts a local stdio MCP server that proxies to https://quantustik.com/mcp. Anonymous use is allowed under a per-IP hourly quota; no setup required.

Optional: raise your quota with an API key

Get a free key at quantustik.com/developers, then set it as an environment variable:

{
  "mcpServers": {
    "quantustik": {
      "command": "npx",
      "args": ["-y", "@quantustik/mcp-server"],
      "env": {
        "QUANTUSTIK_API_KEY": "your-key-here"
      }
    }
  }
}

Environment variables

Variable	Purpose	Default
QUANTUSTIK_API_KEY	Sent as Authorization: Bearer <key> to raise the anonymous per-IP hourly quota.	none (anonymous)
QUANTUSTIK_MCP_URL	Override the remote endpoint (mainly for local development against a non-production instance).	https://quantustik.com/mcp

Any additional CLI arguments you pass are forwarded to the underlying mcp-remote proxy (e.g. --debug).

How it works

npx @quantustik/mcp-server runs a small Node script (bin/quantustik-mcp.js) that spawns mcp-remote against https://quantustik.com/mcp using the http-only transport (our endpoint is streamable-HTTP, not SSE). mcp-remote speaks stdio to your MCP client on one side and streamable-HTTP to our server on the other — this package just pins the URL, transport, and optional auth header so you don't have to remember them.

Source

Server implementation (Python, FastMCP): the hosted endpoint's source lives in mcplafed/autoevolve (app/mcp_server.py, server.json). This wrapper repo only contains the thin npm client shown above.
