Reviewer Notes

AWS Amplify has solid agent tooling through well-documented SDKs and APIs, good reliability as an AWS service, and a free tier for experimentation. However, discovery is hindered by lack of an MCP server or llms.txt file—agents must navigate AWS documentation. Account creation requires AWS account setup with identity verification and payment method on file, making programmatic signup nearly impossible. The pricing model adds friction since scaling beyond the free tier requires credit card authentication upfront. Strongest for agents that already have AWS credentials; weakest for cold-start agent onboarding.
