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.

CLI

Evaluate a ticker directly from the environment where your agent is already working.

$leroy evaluate ABNB
Read the CLI guide

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.

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.

5/5

Match tiers from exact ticker setup to side baseline.

From market memory to a model.

Market Memory gives an agent current context, strategy signals, and historical outcomes. We're developing a paper model on top of that foundation—testing how those signals combine, exposing its decision threshold, and keeping every result inspectable.
