Introduction
Claude Code is an AI-powered development assistant that enhances coding workflows with intelligent tools.
What is Claude code?
Claude Code is a specialized development tool created by Anthropic that integrates directly into a developer's terminal environment. It functions as an intelligent coding assistant, leveraging advanced language models to help with writing, understanding, and maintaining code. The product aims to solve the problem of developer context switching and complex workflow management by providing AI-powered assistance within the natural development environment. A core component of its power is full support for the Model Context Protocol (MCP), which acts like a universal port, allowing Claude Code to connect securely to over 2,000 external data sources and tools through MCP servers. This makes it suitable for software developers, engineers, and technical teams who want to accelerate development, automate repetitive tasks, and interact with their systems using natural language.

Frequently Asked Questions about Claude code
Is Claude Code free to use?
Claude Code is currently in a beta research preview and is not free. Typical usage costs are estimated between $5-10 per developer per day, though costs can be significantly higher during intensive coding sessions.
Where can I try Claude Code?
You can experience general AI capabilities at Claude AI. For access to Claude Code specifically, you need to join the waitlist through the official Anthropic Console.
Is my code safe and secure with Claude Code?
According to the provided information, your code is safe. Claude Code operates directly in your terminal with a direct connection to Anthropic's API, meaning your code and queries do not pass through intermediate servers. The company also states it does not train models on user code or feedback.
What programming languages does Claude Code support?
Claude Code is designed to work with any programming language. It also understands various development tools, frameworks, and can interact with them through the terminal and connected MCP servers.
What is MCP (Model Context Protocol)?
MCP is an open protocol that standardizes how applications provide context to large language models. Think of it as a universal connector, like USB-C, for AI applications, allowing tools like Claude Code to securely interface with thousands of different data sources and services via MCP servers.
How does the Computer Use feature work?
The Computer Use beta runs in a secure, sandboxed environment where Claude can interact with applications through a virtual display. This allows for automation of tasks like UI testing while ensuring the safety and security of the user's primary system.
