Anthropic’s CLI for Claude — the coding agent
Claude Code is Anthropic’s official CLI for coding with Claude. Explore skills, MCP servers, frameworks, and tools built for the Claude Code ecosystem.
npm install -g @anthropic-ai/claude-codeRequires Node.js 18+. Works on macOS, Linux, and WSL.
cd your-project && claudeOpens an interactive session. Claude reads your codebase and helps you code.
Add skills (custom slash commands), MCP servers (external tools), hooks (lifecycle events), and agents for complex tasks.
One command. Takes about 30 seconds.
Check if you have Node.js
node --versionYou need v18 or higher. If you see a number like v20.11.0, you're good. If you get "command not found", go to nodejs.org and install it first.
Install Claude Code globally
npm install -g @anthropic-ai/claude-codeThis installs the claude command on your machine. Runs on macOS, Linux, and Windows (WSL).
Verify it worked
claude --versionYou should see a version number. If you do, you're ready to go.
Point it at your code and start talking.
Open your terminal
On Mac: Spotlight → type "Terminal". On Windows: open WSL or Windows Terminal.
Navigate to your project folder
cd ~/my-projectReplace ~/my-project with the actual path to your project.
Start Claude Code
claudeThat's it. Just type claude and hit Enter.
First time? Log in
It'll open a browser window to authenticate with your Anthropic account. Log in, come back to the terminal, and you're connected.
Start talking
Claude automatically reads your project files. Just describe what you want: "add a login page", "fix the failing test", "refactor this function".
Everything you need to know to not feel lost.

Pro tip: When Claude wants to edit a file or run a command, it'll ask for permission. Press y to allow, n to deny. You can also type ! to allow and stop asking for that type of action.
