Simengine

Overview

Simengine is a Model Context Protocol server that brings Monte Carlo decision-intelligence to AI assistants. It lets you simulate, optimize, and make decisions under uncertainty—all callable as tools within Claude, Cursor, VS Code, and other MCP clients, without switching between apps.

Simengine runs locally via the uvx simengine-mcp command, requiring no authentication or credentials to get started. The Python package communicates with your MCP client over stdio. Version v3.0.1 is published under the Apache-2.0 license, with source code available at cogswellspacely8-star/simengine on GitHub.

Simengine is listed in the Development category on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, claim your listing to earn the Verified badge and keep the information up to date.
