fx_live_priceLABSCO SUMMARY
Quant signals as an answer, not a dashboard.
Two tools cover it: what the price is now, and what a named model says about the pair over a window. The testnet switch is the thing to get right first — production calls carry real payments, and the difference is one environment variable.
What it is
An MCP server for Vongstaad's quant models, giving an agent live prices and historical signals for FX and crypto pairs, published as @vongstaad/mcp-fx.
What you get
- The latest live price for a trading pair such as BTCUSD, ETHUSD or SOLUSD
- A historical quant signal for a pair, from a named model over a chosen window
- Seven models to choose between: sma crossover, latest qualified close price, BTC/ETH Pearson correlation, market regime detection, directional momentum, annualised realised volatility, and z-score mean reversion
- Windows of 7d, 30d or 90d, with regime and mean-reversion available on 30d and 90d
Requirements
Set VONGSTAAD_ENV to testnet for free testing; omitting it selects production, where calls involve real payments. Node, to run it via npx.
Setup effort
One command — npx @vongstaad/mcp-fx
USE CASES
01
Checking where a pair is trading right now
Ask for the live price on BTCUSD, ETHUSD or SOLUSD without opening a terminal.
02
Testing whether a pair is trending or chopping
Read the sma crossover and momentum signals over the same window and compare what they say.
03
Sizing risk before you take a position
Pull annualised realised volatility over 7d, 30d and 90d and see how the picture changes with the window.
04
Judging whether BTC and ETH are moving together
Read the Pearson correlation signal instead of eyeballing two charts side by side.
05
Trying it before it costs anything
Run with VONGSTAAD_ENV set to testnet, which is the free path, and keep production for when the workflow is settled.
