STEM Agent Free

STEM Agent gives the coding agent you already use one complete scientific toolkit, checked workflows, and a simple way to add specialized tools later. The Free Alpha installs 40 standard scientific components and keeps calculated results separate from independent verifier receipts.

STEM Agent is free to download and use. It remains proprietary software and is not open source.

Install

You need Python 3.12 and pipx. Then run:

pipx run stem-agent

The installer verifies its embedded release bundle, creates separate worker and verifier environments, checks all 40 components, runs a verified demo, and creates a tested connection for each of the 15 coding agents listed on the Exergy Lab home page.

Claude Code, Codex, GitHub Copilot CLI, Gemini CLI, Qwen Code, Prime-Agent, Grok Build, Kimi Code, and Hermes Agent connect automatically when their CLI is installed. OpenCode, DeepSeek Harness, MiniMax Code, and NAC receive exact native configuration files without overwriting existing settings. Apodex Agent Harness and Exoharness use the same installed tools through the stable local command line because their current releases do not expose MCP clients.

The release workflow tests Windows 11 x64, Ubuntu 24.04 x64, and macOS 12 or newer on both Apple Silicon and Intel before the package can publish.

No telemetry is sent. Use the local support and feedback commands to create an inspectable, privacy-safe report that you choose whether to share.
