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 STEM Agent
Recommended: use
pipx run stem-agent, not PyPI's genericpip install stem-agentprompt.pipxruns the full installer in its own environment, separate from your other Python projects.
If Python 3.12 and pipx are already installed, run:
pipx run stem-agent
Starting from a new machine? Use the setup assistant. It installs Python 3.12
and pipx, then runs the same STEM Agent command:
Windows PowerShell: irm https://raw.githubusercontent.com/cdimurro/STEM-agent/main/product/install-with-prerequisites.ps1 | iex
macOS or Linux: curl -fsSL https://raw.githubusercontent.com/cdimurro/STEM-agent/main/product/install-with-prerequisites.sh | sh
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.
Install once for each operating-system user account and restart agent sessions that were already open. Every newly opened agent session starts its own local STEM Agent process, so multiple sessions can use the same installation at the same time from the same or different project folders. STEM Agent rejects two simultaneous runs that claim the same declared output file.
Running the same install command again checks the installed release and refreshes detected agent connections without downloading another copy of the scientific environment.
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 15 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.
