View MAESTRO 7-layer threat model →Overview
Magic by 21st.dev creates polished React/UI components on demand from natural-language prompts, delivering ready-to-use code into the developer's project via MCP. It calls 21st.dev's generation backend and writes files. Generated code is untrusted output that lands directly in the codebase, so review of injected code is the relevant concern.
