Free, deterministic, open source. License: MIT. Source: https://github.com/LuxAlgo/prop-firm-sim - [Market Trackers](https://www.luxalgo.com/market-trackers/): The public record, as infrastructure.

Source: https://github.com/LuxAlgo/luxalgo-mcp-server - [Every repository](https://github.com/LuxAlgo): Issues, releases and contributions, in the open. ## Honest by construction. - **Every number carries its sample size.** Edge Stats and Prop Firm Sim put a sample size and a confidence interval on every percentage. - **Historical frequencies, never predictions.** Statistics describe what happened. Simulations state their assumptions. Nothing here promises an outcome. - **Your keys stay on your machine.** Broker SDK and Trade Relay read credentials from your own environment. The hosted LuxAlgo MCP carries no broker tools, on purpose. - **Every row has a source.** Market Trackers links every row to the government document it came from. - **No telemetry.** Trade Journal, Broker SDK, Trade Relay, Prop Firm Sim, Edge Stats and Whale Options send nothing home. ## Every project, one connection. The LuxAlgo MCP serves the family as tools for Claude, ChatGPT, Cursor or any MCP client: the Library, your trade journal, prop-firm simulations, session statistics and the public record of US markets. Keyless for everything public, one sign-in for your journal. - Endpoint (streamable HTTP): https://mcp.luxalgo.com/mcp - Overview: https://www.luxalgo.com/mcp/ ## Built in the open, by the team behind Vela.
