Claude Code is an official terminal-based agentic coding tool developed by Anthropic. Executed via the `claude` CLI command, it provides an interactive assistant environment directly inside developer shells to inspect code, run terminal commands, and perform automated code modifications across local projects. In day-to-day development, Claude Code operates as an interactive agent that reads local file trees, analyzes repositories, writes changes, and executes shell tasks to verify outputs. It connects natively to Anthropic's Claude models, providing deep code comprehension and step-by-step problem-solving directly in the terminal alongside optional IDE integrations. A primary differentiator for Claude Code is its native integration with the Model Context Protocol (MCP). This enables developers to connect local or remote MCP servers, extending the agent's context and capabilities with custom toolsets, database connectors, and enterprise internal APIs. Claude Code supports flexible access models, allowing developers to authenticate and pay through direct Anthropic API billing or via eligible Claude subscription tiers.
