MCP Amplify Docs

An MCP (Model Context Protocol) server that provides AWS Amplify documentation, code examples, and implementation patterns directly within Claude.

🚀 v1.6.0 - Real-World Lambda + DynamoDB Patterns

NEW: Production-tested patterns from actual deployed apps:

1. 📍 Real-World Lambda + DynamoDB - ACTUAL working pattern:

   • Correct import path: @aws-amplify/backend/function/runtime
   • Use process.env directly (NOT $amplify/env)
   • Always specify authMode: 'iam' for Lambda functions
   • Dependencies in root package.json only

2. 🎯 Enhanced Function Best Practices - New real-world-lambda-dynamodb pattern

   • Complete working examples from production apps
   • Common errors and their solutions
   • Proper project structure

Previous Updates (v1.5.0)

This version implements a hybrid approach to prevent common client-side errors:

1. 📍 Automatic Client-Side Reminders - EVERY response now includes critical reminders:

   • Amplify.configure(outputs) requirement
   • Auth mode specification for multi-auth setups
   • Use publicApiKey instead of guest for public access

2. 🎯 New Implementation Checklist Tool - get_amplify_implementation_checklist

   • Comprehensive checklists for auth, storage, data, functions
   • Complete working examples with proper error handling
   • Auth mode decision trees

This update specifically addresses the three most common Amplify errors that occur in browser consoles, ensuring Claude provides correct implementation guidance from the start.
