Claude Code Security Guide
Security best practices for Claude Code users. Protect your codebase, credentials, and development environment from AI agent attacks.
Overview
Claude Code is Anthropic's AI coding assistant that operates directly in your terminal with access to your filesystem, git repositories, and shell. While powerful, this access level requires careful security configuration. This guide covers hardening your Claude Code setup against prompt injection (via code comments, README files, dependency descriptions), credential protection (using tools like Secretless AI), and MCP server security.
Features
- -CLAUDE.md governance file configuration
- -Permission boundary setup
- -MCP server allowlisting
- -Credential protection with Secretless AI
- -Git hook security (pre-commit scanning)
Security Considerations
Claude Code reads CLAUDE.md files, which means any repository you clone can influence the agent's behavior. Always review CLAUDE.md in unfamiliar repos before opening them with Claude Code. Use HackMyAgent to scan repos before working in them.
