HPSILab Quant Finance MCP Server for Stock & Options Analytics

HPSILab is an open-source Python quantitative finance MCP server for research on US equities, ETFs, and supported options. It brings stock signals, implied volatility, options analytics, Monte Carlo simulation, AI prediction, backtesting, and risk analysis into ChatGPT, Claude, Cursor, VS Code, and other MCP clients. Connect once, ask in natural language, and receive structured results that an assistant can compare and explain.

Monte Carlo research example

Example visualization of scenario-based Monte Carlo research output. Results depend on the selected inputs and model assumptions. See get_monte_carlo for tool details.

Quick start: Official Remote MCP

The hosted Streamable HTTP service is recommended and requires no local installation. The following is a Claude Code .mcp.json example; other clients use different configuration schemas, documented below.

{
  "mcpServers": {
    "hpsilab": {
      "type": "http",
      "url": "https://hpsilab.com/mcp",
      "headers": {
        "Authorization": "Bearer hpsi_your_key"
      }
    }
  }
}

1. Register a free account, sign in, and generate an API key from Settings.
2. Replace hpsi_your_key in your client's private MCP configuration. Never commit or paste a real key into chat.
3. Connect the server and verify it with:

Use HPSILab to analyze AAPL. Separate observed metrics from interpretation,
identify conflicting signals, and finish with a concise risk summary.

All financial research tools require a valid API key. See client setup and authentication for details.

Quick start: Local stdio

For clients that require local stdio:

pip install -U hpsilab-quant-finance-mcp

With HPSILAB_API_KEY configured, direct Python usage is:

import hpsilab_quant_finance_mcp
from hpsilab_quant_finance_mcp import server

print(hpsilab_quant_finance_mcp.__version__)

result = server.get_ai_prediction("NVDA")
print(result)

For MCP, add the stdio server to the client's private configuration. This example uses the mcpServers schema supported by Claude and Cursor; VS Code and GitHub Copilot use a servers schema instead.

{
  "mcpServers": {
    "hpsilab": {
      "command": "hpsilab-quant-finance-mcp",
      "env": {
        "HPSILAB_API_KEY": "hpsi_your_key"
      }
    }
  }
}

Then verify it through the MCP client:

Use HPSILab to get the AI prediction for NVDA and summarize the model consensus.

The client discovers tools with MCP tools/list and invokes them with tools/call. See local setup and Python usage.

Why HPSILab

HPSILab gives assistants typed inputs, structured outputs, ticker validation, machine-readable errors, and dedicated tools instead of invented metrics. It supports US-listed equities, ETFs, and supported options data; coverage and limits depend on the hosted service and plan.

Tools

The public product surface contains 9 public financial research tools.

Research tools accept one exchange ticker such as NVDA, SPY, or BRK.B; company names are not accepted. Live results can change between calls. Artifact tools can consume quota and should not be retried automatically.

Full inputs, outputs, side effects, and tool-selection guidance are in docs/tools.md.

Copy-ready prompts

Claude

Use HPSILab to analyze NVDA. Summarize the directional signal, AI model
consensus, IV regime, options pressure, 30-day Monte Carlo range, and the
three most important risks. Distinguish tool data from interpretation.

Cursor

Use HPSILab's IV radar and option-pressure tools for SPY. Compare IV rank,
percentile, skew, expected move, max pain, gamma wall, and pressure zones.
Return a compact table and do not recommend a trade.

ChatGPT

Run the HPSILab pre-trade risk scan for TSLA. Explain every warning or failed
check, preserve unavailable fields as unavailable, and quote the returned
reason instead of guessing. Do not execute or recommend a trade.

Setup guidance covers ChatGPT, Claude, Cursor, VS Code, GitHub Copilot, Continue, and Kimi. See the client setup guide for each client's transport and configuration format.
