Amp CLI

Amp is an agentic coding tool built by Sourcegraph. It runs in VS Code (and compatible forks like Cursor, Windsurf, and VSCodium) and as a command-line tool. It's also multiplayer — you can share threads and collaborate with your team.

Installation

Install globally with your preferred package manager:

pnpm add -g @sourcegraph/amp
# or
yarn global add @sourcegraph/amp
# or
npm install -g @sourcegraph/amp

Alternatively, run without installing:

npx @sourcegraph/amp

Usage

After installation, run:

amp

See Amp Owner's Manual for more information about Amp.

Authentication

Option 1: Interactive Login (Recommended)

The first time you run amp, use the login command to authenticate via ampcode.com:

amp login

This opens your browser to complete authentication. Your threads will be synced and shareable across all clients.

Option 2: API Key Environment Variable

If you can't use the interactive flow, set your API key as an environment variable:

1. Go to ampcode.com/settings to get your API key
2. Set it in your environment:

export AMP_API_KEY=your-api-key-here

Proxies and Certificates

The Amp CLI supports proxy servers and custom certificates for corporate environments. See the Proxies and Certificates section in the Amp Owner's Manual for configuration details.
