Inputs
The agent sends the setup it is considering. Leroy does not need a candle dump or a giant prompt.
Request Body
POST /api/mcp
{
"symbol": "AAPL",
"side": "buy",
"entry_price": 212.34,
"holding_horizons": [15, 30]
}Market evidence through MCP.
Connect Leroy to the agent or workflow you already use. Rank current signal confluence in one snapshot, then send a ticker and side for historical context, outcomes, and explicit limits.
No card required. Free accounts include 100 lookups each month.
From request to response.
Scroll through the five passes behind a MCP answer. Every step adds context before Leroy returns the evidence.

Agent Wake
Set a rule. Wake your agent.
Tell Leroy what to watch. When a fresh live setup meets the rule, Leroy wakes your trading agent and sends the evidence it needs to decide what happens next.
The delivery is a signed HTTPS webhook with current quote context, signal confluence, match strength, historical outcomes, provenance, and an explicit research-only boundary. Leroy never places an order.
Create a Wake Rule01
Set the rule
Choose a ticker, side, confluence, evidence strength, and outcome threshold.
02
Leroy watches
Only fresh frames during the regular market session can trigger a wake.
03
Your agent decides
Your endpoint receives a signed evidence packet and remains responsible for any action.
The operating loop
A rule is durable. A wake is event-driven. The payload is auditable.

Ask get_current_confluence_leaders for the current quote-fresh symbols with the most active signal agreement. It is one scanner snapshot and one lookup; follow it with evaluate_current_setup when a specific ticker needs historical evidence.
