Quick start

Quick start

You need Node.js 22.14 or newer. In a terminal, run one command:

npx -y @4thtech-io/agentlink init

It finds your AI tools, shows you the exact change to their settings, and writes it only after you confirm. Then restart the tool.

Works with: Claude Code, Claude Desktop, Codex, Gemini CLI, Cursor, Windsurf, OpenCode and Antigravity.

Protect your approvals

• Published 0.2.0: run npx -y @4thtech-io/agentlink owner init in a terminal you opened yourself. It sets an owner code. It is shown once. Save it in a password manager right away. It cannot be recovered.
• In 0.3.0 (releasing): init opens the first-run page in your browser. One Touch ID or passkey protects your approvals, then your backup code is shown once. See Using the local app.

Or ask your agent

Install AgentLink for me. Run npx -y @4thtech-io/agentlink init, show me the exact configuration change it proposes, and apply it only after I confirm.

Claude Desktop

There is also a one-click bundle, signed by 4thTech, on the latest release page.
