How Eon built multi-cloud investigation with an MCP Gateway on Amazon Bedrock AgentCore
Machine Learning Blog
This article describes how Eon used Amazon Bedrock AgentCore Gateway to replace per-tool credentials and local MCP processes with a single authenticated gateway for multi-cloud investigation tools.
- Consolidated credentials across AWS, GCP, and Azure into one SSO login through Cognito
- Eliminated local MCP server setup; developers now access hundreds of tools from a single gateway URL
- Implemented Cedar-based least-privilege policies for identity separation between humans and autonomous agents
- Achieved cross-account connectivity using IAM role assumption instead of VPC peering or PrivateLink
- Reduced developer onboarding time from 2 days to 2 minutes
- Deployed hybrid DEFAULT and DYNAMIC policy modes to manage Cedar policy size at scale
- Processed 10,000+ sessions across 100+ developers without per-tool token management
Eon's single-gateway architecture demonstrates how AgentCore enables unified tool access for developers and autonomous agents across multiple clouds with centralized policy enforcement.
