This MCP server automates React Native project upgrades by analyzing version differences and providing detailed migration guidance.
Key Capabilities:
Version Discovery & Validation: Fetch the latest stable React Native version, retrieve available Release Candidate (RC) versions for pre-release evaluation, and validate user-specified semantic version numbers
Upgrade Diff Generation: Create comprehensive diffs between any two React Native versions (current to target, including upgrades and downgrades) showing:
Package.json dependency changes
iOS configurations (Podfile, Xcode settings)
Android configurations (build.gradle, settings.gradle)
Project structure modifications
Native code and binary file updates
Template file changes
Migration Guidance: Provide step-by-step instructions for applying changes while:
Preserving custom configurations and user code
Updating only necessary dependencies
Handling build tooling updates
Offering troubleshooting steps tailored to your package manager (pod install, Gradle wrapper updates, dependency reinstallation)
Smart Version Management: Automatically detects the current version from package.json and ensures proper semantic versioning throughout the upgrade process
Provides automated tools for upgrading React Native CLI projects between versions, generating detailed upgrade/downgrade diffs and step-by-step migration guidance using rn-diff-purge
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@React Native Upgrader MCP show me the diff between React Native 0.72 and 0.73"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
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.
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.
