hpsilab-mcp 0.6.0

Python SDK for the HPSILab quantitative finance API — options analytics, IV surface modeling, Monte Carlo simulation, and AI-driven predictions, with native MCP support.

HPSILab Python REST SDK

hpsilab-mcp is the official Python SDK for the hosted hpsilab.com REST API — quantitative finance and options analytics (IV surface, Monte Carlo simulation, AI predictions, pre-trade risk scans, and more).

Note: This package wraps REST endpoints only. It does not implement MCP transport — see MCP Transport below if you need that.

Requirements

• Python >= 3.9

Installation

pip install hpsilab-mcp

To let the client pay per call when the free quota runs out (see Paying past the free quota):

pip install "hpsilab-mcp[x402]"

Quick Start

from hpsilab_mcp import HpsiMcpClient

client = HpsiMcpClient()

calls = {
    "analyze_stock": client.analyze_stock("NVDA"),
    "get_ai_prediction": client.get_ai_prediction("NVDA"),
    "get_iv_radar": client.get_iv_radar("NVDA"),
    "get_option_pressure": client.get_option_pressure("NVDA"),
    "get_pretrade_risk_scan": client.get_pretrade_risk_scan("NVDA"),
    "get_monte_carlo": client.get_monte_carlo("NVDA"),
    "get_equity_curve": client.get_equity_curve("NVDA"),
    "generate_stock_images": client.generate_stock_images("NVDA"),
    "generate_stock_research_report": client.generate_stock_research_report("NVDA"),
}

print(calls["analyze_stock"])

Authentication

All listed REST SDK methods are callable without an API key. The SDK does not block any method client-side; any access restrictions are enforced server-side.

from hpsilab_mcp import HpsiMcpClient

client = HpsiMcpClient(
    api_key="YOUR_API_KEY",
    base_url="https://hpsilab.com",
)

result = client.get_ai_prediction("TSLA")
print(result)

Pass an api_key to raise rate limits or unlock account-specific features, where applicable.

Paying past the free quota

Anonymous callers get a per-tool daily quota. Once it runs out — or when calling a Pro tool, which has no anonymous allowance — the API answers HTTP 402 with an x402 payment challenge instead of refusing outright, so an agent can pay for the call in USDC on Base and keep working.

Without a wallet the SDK raises HpsiMcpPaymentError with the challenge attached, and you can pay it however you like:

from hpsilab_mcp import HpsiMcpClient, HpsiMcpPaymentError

try:
    client.get_monte_carlo("NVDA")
except HpsiMcpPaymentError as exc:
    print(exc.tool, exc.price)   # get_monte_carlo $0.10
    print(exc.accepts)           # scheme / network / asset / amount / payTo

With a wallet, the client signs the challenge and repeats the request for you:

from hpsilab_mcp import HpsiMcpClient, X402Wallet

client = HpsiMcpClient(wallet=X402Wallet(PRIVATE_KEY, max_price_usdc=0.20))
client.get_monte_carlo("NVDA")   # free while quota lasts, paid after that

X402Wallet() reads HPSILAB_X402_PRIVATE_KEY when no key is passed, and a client with no wallet= picks that variable up automatically. Three things hold regardless of how it is configured:

• Nothing is paid pre-emptively — the free call is always attempted first.
• Each call is retried once after paying; a server that keeps answering 402 cannot drain the wallet.
• max_price_usdc (default $1.00) caps a single call. A challenge asking for more is refused, not signed.

Signing happens locally; the private key never leaves your process.

Tool	Price per call
analyze_stock, get_pretrade_risk_scan	$0.15
get_monte_carlo	$0.10
get_iv_radar, get_option_pressure, get_ai_prediction, get_equity_curve	$0.05
generate_stock_research_report	$0.35

Version

import hpsilab_mcp

print(hpsilab_mcp.__version__)

Request tracking

Every request carries X-HPSILAB-Source: sdk, X-HPSILAB-Client: python-sdk, X-HPSILAB-Version: <installed version>, X-HPSILAB-Tool: <method name> (e.g. get_ai_prediction), and User-Agent: hpsilab-python-sdk/<version>. These are merged into any custom headers you pass to HpsiMcpClient(...) without overriding Authorization or other business headers.

REST SDK Methods

Method	Endpoint
analyze_stock(symbol)	GET /api/analyze_stock/{symbol}
get_ai_prediction(symbol)	GET /api/ai_prediction/{symbol}
get_iv_radar(symbol)	GET /api/iv_batch?symbols={symbol}
get_option_pressure(symbol)	GET /api/option_pressure/{symbol}
get_pretrade_risk_scan(symbol)	GET /api/pretrade-risk-scan?symbol={symbol}
get_monte_carlo(symbol)	GET /api/monte_carlo/{symbol}
get_equity_curve(symbol)	GET /api/equity_curve/{symbol}
get_equity_curves(symbol)	Deprecated alias of get_equity_curve — warns on use
generate_stock_images(symbol)	POST /api/stock_report/{symbol}/images
generate_stock_research_report(symbol)	POST /api/stock_report/{symbol}/research_report

The SDK itself does not publish MCP tool annotations; those are declared by the MCP server in its tools/list response. The GET analysis methods are read-only. The two generate_* methods create or refresh hosted artifacts and may consume quota or trigger payment; repeated calls are not guaranteed to be idempotent.

MCP Transport

All official MCP tools have REST SDK coverage. Use an MCP-compatible client (e.g. Claude, or any MCP host) when you specifically need MCP transport, tool discovery, or assistant-native tool calls — see the MCP server docs for setup.

Scope

This package is a REST API wrapper only. It does not implement MCP transport, SSE, streaming, tool discovery, Claude integration, or proprietary finance logic.

These tools return research-oriented information. They are not financial advice.
