Quantustik MCP server — quantum-model S&P 500 analytics

Quantustik is a risk-first market-intelligence layer for humans and AI agents — calibrated probabilistic forecasts, transparent track records, and machine-readable decision support through REST and MCP. It forecasts S&P 500 price paths with a quantum-mechanics model (the Schrödinger equation and Feynman path integrals), layers a machine-learning classifier and a market-conditions read on top, and turns the result into risk-first BUY / WAIT / AVOID / EXIT signals — each with entry price, stop-loss, take-profit ladder and position sizing, plus calibrated 90% confidence bands and a live, auditable track record that includes the losses.

What the analysis gives you, per ticker and for the whole index:

• a signal with the full trade plan behind it (only actionable at ≥2:1 reward-to-risk), and a two-sided explanation of why the model made the call;

• multi-horizon price forecasts (1mo / 3mo / 6mo / 1y) with measured, published calibration — never a bare point estimate;

• whole-universe scans (conviction / direction / sector filters), a risk-vetted shortlist of asymmetric setups, market conditions and an overheating gauge, backtests, fundamentals, dividends and more — 24 tools in total.

Who it is for: AI agents and their users doing market research — analysts, self-directed investors, and anyone who wants honest, uncertainty-explicit market context inside Claude, Cursor, ChatGPT or any other MCP client. Bullish calls are deliberately rare and earned: the model prefers saying WAIT to flattering you.

Educational research only — not investment advice. Nothing here is a recommendation to buy or sell any security. Calibration is measured, not guaranteed; past model performance does not predict future results.

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

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.
