Build a daily dependency watcher with LangGraph and Amazon Bedrock AgentCore web search
Machine Learning Blog
This article demonstrates how to build a daily dependency watcher for security teams using LangGraph and Amazon Bedrock AgentCore's Web Search API to monitor open source packages and container images.
- Web Search API provides current, cited web results through AWS credentials without third-party search engines
- LangGraph orchestrates parallel research branches for npm, PyPI, and container base images ecosystems
- Evidence checks validate findings against search sources, ensuring package names and CVE IDs appear in cited sources
- LangGraph store prevents duplicate reporting across daily runs
- Deploy on AgentCore runtime for scheduled jobs or scale across teams using AgentCore Gateway
- Three parallel branches complete in 36 seconds versus 99 seconds sequentially
The solution shows how to keep search rules in code, validate findings against sources, and deploy production-ready agents with web search capabilities on AWS infrastructure.
