Claude Code

Claude Code is Anthropic's official agentic coding tool, built to run directly in your terminal (and integrate with VS Code and JetBrains IDEs). It can read and edit files across a codebase, run shell commands and tests, and search the web — all from natural-language instructions.

It speaks MCP natively: any MCP server you configure becomes available to Claude Code as tools, letting it reach beyond the local filesystem into databases, APIs, issue trackers, and other systems a project depends on. It also supports subagents, hooks, custom slash commands, and a plan mode for reviewing multi-step changes before they run.
