Connect to the trading stack you already use.
Bring Leroy into the same agent workspace you use to research and trade. It adds current context and historical evidence before execution.
The same evidence, wherever your agent runs.
Use the CLI from a terminal or connect through MCP. Both interfaces reach the same Market Memory and return structured evidence your agent can reason over.
MCP
Give an agent a direct research tool with explicit status, context, and historical outcomes.
Set a wake rule through MCP, and Leroy will wake your agent with signed evidence when a fresh setup matches.
connect leroy / research
See example requests From request to response.
Scroll through the five passes behind a CLI or MCP answer. Every step adds context before Leroy returns the evidence.
Inputs
The agent sends the setup it is considering. Leroy does not need a candle dump or a giant prompt.
