React Native Upgrader MCP Server

A Model Context Protocol (MCP) server that streamlines React Native project upgrades. It provides developers with automated tools to seamlessly upgrade React Native CLI projects to any desired version or the latest stable release. The MCP Server uses rn-diff-purge to generate the diff.

🚀 Features

• Version Management: Fetch and track the latest stable React Native versions with semantic versioning support
• Upgrade Automation: Generate detailed upgrade/downgrade diffs between versions with step-by-step migration guidance
• Release Candidate Support: Access and evaluate pre-release versions for early testing and feature validation

Important: This MCP Server is not compatible with Expo projects.
