Add travel assistant and flight booking agents - Strands + A2A Agentcore

[pkdey-aws]

Add Travel Booking Agents with Strands Framework

Closes #196, #197

Overview

This PR adds two AI agents built with AWS Bedrock AgentCore and the Strands framework for flight search and booking functionality. Follows the specs declared in 196 and 197 for database, frameworks and API endpoints required.

What's New

Travel Assistant Agent (travel_assistant_agent)

• Searches for available flights between cities
• Provides flight recommendations based on price and preferences
• Returns detailed flight information (times, prices, airlines)
• In memory SQLite DB

Flight Booking Agent (flight_booking_agent)

• Checks flight availability and seat counts
• Creates flight reservations
• Manages booking database
• In memory SQLite DB

Project Structure

These agents are implemented in a separate agents-strands/ directory as a standalone project. This approach keeps the Strands-based implementation isolated from the original agents/ directory, which uses LangChain/LangGraph. By maintaining separate directories, we avoid mixing different agent frameworks and preserve the existing project structure.

The agents support two deployment modes:

• Local Docker Container: Containerized FastAPI servers running on available through local 9001 and 9002
• Live into AWS Account: Quick deploy script uses Agentcore CLI to create or update to Agentcore Runtime

cd agents-strands
./deploy_local.sh  # Deploy local docker containers 
./deploy_live.sh    # Deploy to AWS account

Key Differences between Local and Live

Agentcore runtime only supports exposing the main A2A interface path which is arn/

Feature	Local Docker	AgentCore Runtime
A2A Protocol	✅	✅
Custom API Endpoints	✅	❌
Health Check /ping	✅	✅
Deployment	Docker Compose	AgentCore CLI

Testing

Simple test scripts to invoke the agents

cd agents-strands/tst
python3 simple_agents_test.py --endpoint local  # Test Docker
python3 simple_agents_test.py --endpoint live   # Test AgentCore

More information in the README of the agents-strands/ directory.

What's next for MCP Registry Gateway project?

When the MCP Gateway Registry service supports agent registry, these agents could be automatically hooked up and registered before the service starts. There are TODO markers for possible integration points.
