MADDOG MCP Server
[Listed on mcpservers.org]
Price-action session reads for AI agents — measured statistics, not opinions.
Endpoint: https://api.maddog.finance/mcp · stateless streamable HTTP · plain-JSON responses, no session to manage.
MADDOG reads a market session the way a price action trader does, and every number it
returns is a historical frequency with a published measurement behind it — never a
forecast, never a recommendation:
- a five-class day-type probability distribution — 66% top-1 accuracy over a complete
US day session against a 37% majority-class baseline, with a confidence grade whose
published accuracy ranges from 95% (best grade) to 41% (worst);
- the window's first range breakout with a calibrated per-event failure estimate
(AUC 0.646, calibration error 5.1%, n=2,637, validated on held-out NQ);
- from the 90-minute mark, the measured odds that a new session high or low still
prints before the close (69% by day type vs a 48% base rate, held out on 576
sessions the model never saw).
Covers US stocks and ETFs, futures (ES=F), FX, crypto, Hong Kong and China A-shares.

Why trust the numbers
The claims above were pre-registered before being published and the live model is
scored in public every trading day: the scoreboard
shows each 11:00 ET call next to what the session actually did, including the days the
model was wrong and the days no read was taken. The same data is served raw and keyless
at /v1/scoreboard.
