Vault-alexa-mcp

VaultAlexa+ is a two-sided autonomous AI agent built on Amazon's MCP Protocol (2025-11-25 spec) that bridges consumers and Amazon sellers.

FOR BUYERS: • Snap a product photo → Amazon Nova Pro (via AWS Bedrock) instantly analyzes the image and compares live prices across Amazon, Best Buy, and Walmart • "Alexa, can I afford this?" — voice-powered budget guard prevents impulse purchases • Proactive deficit forecast warns you before upcoming bills drain your account • Anti-impulse 24h cooldown + opportunity cost simulation ("This $200 buy = 4 months of Netflix")

FOR SELLERS: • AI generates complete Amazon FBA listings from product photos — title, bullets, pricing strategy, FBA tier • Real-time inventory stockout prediction with auto PO drafting • Dynamic Buy Box repricing to maintain 95%+ win rate • Revenue analytics dashboard with order dispatch monitoring

TECHNICAL HIGHLIGHTS: • Full MCP JSON-RPC 2.0 server with 13 tools, 3 resources, 2 prompts • Amazon Nova Pro multimodal vision via AWS Bedrock (SigV4 IAM auth) • Streamable HTTP + SSE + Stdio transport — all three MCP transports • Bilingual UI: English / Bahasa Indonesia • 9/9 automated MCP compliance tests passing
