@getcolter/cli

Check if any online store works with AI shopping agents.

Colter tests both major agent commerce protocols in one command:

• UCP (Universal Commerce Protocol) — product discovery, browsing, and purchase. Used by Gemini, AI Mode, Copilot, and others.
• ACP (Agent Commerce Protocol) — checkout and payment. Used by ChatGPT, Operator, and others.

Produces Evidence Packs: portable, redacted, replayable records of every verification.

Install

npm install -g @getcolter/cli

Or run directly:

npx @getcolter/cli check https://your-store.com

Platforms

Pre-built binaries for macOS (ARM64, x64), Linux (x64, ARM64), and Windows (x64).

Integrity

Release tags (vX.Y.Z) create a GitHub Release that includes checksums.txt (SHA-256) for each platform binary.

If you need to verify the installed binary:

• Download checksums.txt from the GitHub Release for your version.
• Compute the SHA-256 of your local binary and compare.

On macOS/Linux:

sha256sum "$(command -v colter)"
