🏠 FrontDoor Concierge

AI-Powered Smart Doorbell Guardian & Alexa+ Model Context Protocol (MCP) Agent

FrontDoor Concierge transforms smart doorbells from passive notification buzzers into an intelligent front-porch concierge and security guardian. Built with Amazon Bedrock (Claude 3.5 Sonnet Multimodal Vision), Ring's Developer Ecosystem via ring-client-api, and a Self-Hosted Model Context Protocol (MCP) Server (Spec 2025-11-25 / Streamable HTTP) for Alexa+, it continuously perceives visitors, identifies delivery couriers, computes real-time porch piracy risk scores, generates 1-time courier smart lock PINs, and powers conversational Alexa+ voice agent workflows.

🛠️ Registered Model Context Protocol (MCP) Tools

The self-hosted MCP server exposes 6 high-utility tools to Alexa+ and agentic skills via POST /mcp (Streamable HTTP):

1. check_front_door_status: Inspects live camera state, active threats, and recent porch events.

2. inspect_latest_delivery: Queries courier identity (Amazon, UPS, FedEx), package size, delivery timestamp, and Bedrock confidence.

3. speak_to_visitor: Delivers an audible instruction through the Ring doorbell two-way speaker.

4. generate_smart_lock_pin: Creates a temporary 1-time access PIN (e.g. 15-minute PIN) for trusted couriers or guests to unlock the porch parcel box or gate.

5. escalate_threat_alert: Triggers high-risk emergency protocol (90dB siren, emergency mobile push notification, and evidence snapshot).

6. query_daily_analytics: Aggregates today's delivery metrics, courier breakdown, and security alerts.

✨ Key Features

1. Autonomous Courier Identification:

   • Classifies uniforms and packages across Amazon Logistics, UPS, FedEx, USPS, and DHL with confidence metrics.

2. Porch Piracy & Threat Scoring (0–10):

   • Assesses dwell time, body posture, face concealment, and package tampering to compute an actionable risk score.

   • Triggers dynamic red alert pulses, sirens, and audio warnings if risk exceeds safety thresholds.

3. Conversational Alexa+ Voice & MCP Simulator:

   • Web-based conversational agent simulator with speech-to-text / text-to-speech.

   • Interactive Live MCP JSON-RPC 2.0 Payload Inspector showing the exact request and response envelopes in real time.

4. Smart Lock & Access Control Hub:

   • Generates temporary, time-decaying 4-digit PINs for delivery couriers to unlock porch delivery boxes.

5. Resilient Dual-Mode Operation:

   • Production Mode: Connects directly to authenticated Ring accounts via RING_REFRESH_TOKEN to monitor actual hardware doorbells and camera snapshots.

   • Simulator Mode: Fully operational standalone experience for judges, equipped with 5 pre-configured scenarios (Doorbell Delivery, Motion Alert, Package Dropped, Visitor Arrived, Suspicious Threat).

🚀 Quick Start Guide

Prerequisites

• Node.js: v18.0.0 or later

• npm: v9.0.0 or later

AWS_REGION=us-east-1
AWS_ACCESS_KEY_ID=your_access_key
AWS_SECRET_ACCESS_KEY=your_secret_key
BEDROCK_MODEL_ID=anthropic.claude-3-5-sonnet-20241022-v2:0

# Ring Credentials (Optional: launches simulator mode if omitted)
RING_REFRESH_TOKEN=your_token

# Server & Client Ports
PORT=3001
CLIENT_URL=http://localhost:5173

3. Launch the Application

Run both the backend API and frontend Vite dev server concurrently:

npm run dev

• Frontend Dashboard: http://localhost:5173

• MCP Server Endpoint: http://localhost:3001/mcp

• MCP SSE Stream: http://localhost:3001/mcp/stream

🎮 Hackathon Demo Scenarios

Mode A: Porch Guardian View

1. Ring Doorbell (Amazon Delivery): Simulates an Amazon Logistics courier ringing the bell. Bedrock detects the uniform, greets the driver, and marks risk as low (1/10).

2. Threat Detected (Porch Piracy Attempt): Flags suspicious loitering and package tampering. Instantly triggers screen shake, high-risk banner (9/10), and emergency dispatch recommendations.

Mode B: Alexa+ Voice & MCP Console View

1. Click the 🗣️ Alexa+ MCP Agent tab in the top navigation bar.

2. Click "Alexa, who is at the front door?" ➔ Watch Alexa execute the check_front_door_status MCP tool and inspect the JSON-RPC 2.0 payload!

3. Click "Alexa, generate a PIN for the UPS driver" ➔ Watch Alexa generate a temporary 4-digit smart lock PIN valid for 15 minutes.

4. Switch to the 🔐 Smart Lock tab to see active codes and validity countdowns.

5. Switch to the ⚡ MCP Tools tab to inspect all 6 registered tool JSON schemas.

Mode C: Panoramic Split View

Click 🔀 Split View to view the live camera HUD, parcel timeline, and Alexa+ MCP voice console side-by-side.
