Anthropic's Claude Code adds deny rules for sensitive file access

By PulseAugur Editorial · [1 sources] ·

Anthropic's Claude Code now allows users to implement permission deny rules to prevent the AI from accessing sensitive files such as .env files, private keys, or cloud credentials. These rules can be configured in shared team settings or personal configuration files, ensuring that Claude Code cannot read specified paths even if broader read permissions are granted. This feature enhances security by allowing users to explicitly block access to critical information, with options to deny specific file patterns or even outbound commands like Bash curl. AI

IMPACT Enhances security for AI coding assistants by allowing users to control access to sensitive files.
