Env
This gives Claude direct access to your development environment through tools for parsing dotenv files, checking port availability, and inspecting system info. You get operations like env_list_variables to see what's in your .env, env_compare_files to diff against .env.example, port_check to identify what's using port 3000, and system_info for OS and runtime versions. The env_generate_example tool creates sanitized templates by stripping values while preserving structure. Useful when Claude needs to troubleshoot configuration issues, verify dependencies are installed, find an open port for a new service, or detect missing environment variables before deployment.
