Migrate vanilla JavaScript apps and pages to React — full rewrites or incremental strangler-fig migrations of any size, from script-tag pages to ES-module apps.
https://mcp.context7.com/mcpUse this server to fetch current documentation whenever the user asks about a library, framework, SDK, API, CLI tool, or cloud service — even well-known ones like React, Next.js, Prisma, Express, Tailwind, Django, or Spring Boot. This includes API syntax, configuration, version migration, library-specific debugging, setup instructions, and CLI tool usage. Use even when you think you know the answer — your training data may not reflect recent changes. Prefer this over web search for library docs.
Do not use for: refactoring, writing scripts from scratch, debugging business logic, code review, or general programming concepts.
