What is the HEA MCP server?

High-entropy alloy and oxide descriptors and phase-prediction rules, with provenance. Exposed over MCP by the hea mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

What it actually does

Open, interpretable tools for computing the standard high-entropy-alloy (HEA) and high-entropy-oxide (HEO) thermodynamic and geometric descriptors and the classic empirical phase-prediction rules, from any composition, with no fitted model and no black box. Every number is a transparent closed-form expression over a curated element-property table, validated against the primary literature.

Adding it to your client

Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.

Its toolset

Everything the assistant can do here goes through one of these:

  • Phase — prediction rules:** Yeh entropy, Zhang δ, Guo–Liu VEC,
  • High — entropy oxides** (hea_bench.oxides + the apps' Oxides mode):
  • Surface — Where

Caveats

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the hea mcp server does with a few real requests.

When to reach for it

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. HEA's toolset — Phase, High, Surface — is a fair guide to whether it matches your workflow. It is maintained by dfieser; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

How to install the HEA MCP server

{
  "mcpServers": {
    "hea-bench": {
      "command": "uvx",
      "args": ["hea-bench"]
    }
  }
}

Add to claude_desktop_config.json, then restart Claude Desktop.

Example prompts to try

  • Use HEA to Phase.
  • Use HEA to High.
  • Use HEA to Surface.

Frequently asked questions

It connects HEA to MCP-compatible AI assistants such as Claude and Cursor, exposing 3 tools (Phase, High, Surface) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with HEA directly.
