Lockbox

Lockbox is an MCP (Model Context Protocol) server and toolkit that enables encrypted secrets management for Next.js applications, allowing developers to securely store, access, and rotate environment secrets without the need for an external vault. It uses AES-256-GCM encryption and is designed for teams building AI-enabled products and agent-native infrastructure, particularly those integrating with AI assistants or deploying on CI/CD. Lockbox integrates directly with the Next.js ecosystem and offers both CLI and TypeScript APIs for flexible usage in modern development workflows.
