Inspiration
Field service dispatch and contractor coordination often rely on vulnerable communication channels, manual scheduling delays, and unverified work orders. We created LocalPro Enclave to bring zero-trust security and proactive ambient intelligence to trade services using Alexa+ and Model Context Protocol (MCP).
What it does
LocalPro Enclave is an autonomous, zero-trust dispatch agent built for Alexa+. It processes hands-free voice requests to verify contractor identity, orchestrate trades, optimize local scheduling via MCP, and maintain cryptographically secured authorizations with edge enclaves.
How we built it
- Voice Interface: Custom Alexa+ conversational interaction model built with the Alexa Skills Kit (ASK) for ambient dispatch requests and spoken confirmations.
- Context & Tool Routing: Model Context Protocol (MCP) integration to securely connect the agent with local trade calendars, technician availability, and inventory data.
- Serverless Execution: AWS Lambda handles real-time voice fulfillment, trade dispatch routing, and policy execution.
- Frontend Interface: Cross-platform Flutter client for field technicians and admins to track jobs, review cryptographic tokens, and manage schedules.
- Data & Enclave Security: Amazon DynamoDB for low-latency schedule synchronization, paired with AWS Key Management Service (KMS) for zero-trust access verification.
Challenges we ran into
- Balancing conversational flexibility on Alexa+ with deterministic, zero-trust access boundaries.
- Coordinating multi-party dispatch (client, dispatcher, and technician) with low latency across voice and mobile clients.
- Structuring resilient offline failovers when field technicians lose local network connectivity.
Accomplishments that we're proud of
- Designing a hands-free workflow where complete service calls can be secured, matched, and dispatched via simple voice interactions.
- Seamless event orchestration linking Alexa voice commands directly to Flutter mobile apps and AWS serverless infrastructure.
What's next for LocalPro Enclave
- Multi-modal visual dash cards for Echo Show and smart displays with live map routing.
- On-device voice biometric authentication for high-value contractor payments and work order sign-offs.
- Automated IoT sensor integration to trigger preventive maintenance dispatch automatically before equipment failures occur.
