HEA-Bench

Overview

HEA-Bench is a Model Context Protocol server that brings high-entropy alloy and oxide analysis directly to your AI assistant. It provides descriptors, phase rules, materials properties, and design tools for high-entropy materials research, letting Claude and other MCP clients access these capabilities as native tools rather than through manual workflows.

The server runs locally on your machine via the Python package hea-bench, installed with uvx hea-bench. No authentication or external credentials are needed—it works immediately after installation. Version v2.5.6 is available under the MIT license, with full source code at dfieser/hea-bench on GitHub.

HEA-Bench is listed in the Development category and works with any MCP client including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, you can claim this listing to verify ownership and keep the information up to date.
