AWS Launches AgentCore Gateway for Multi-Account AI Agents via MCP
AWS has released AgentCore Gateway, a managed control plane that enables AI agents to operate across multiple AWS accounts using the Model Context Protocol (MCP), centralising tool access and identity brokering for distributed agentic workloads. For defenders, this closes a meaningful gap in cross-account agent governance by providing a structured integration layer that enforces IAM-scoped tool invocation rather than relying on ad-hoc credential passing between accounts. Residual gaps remain around MCP server vetting maturity, cross-account audit log correlation, and the organisational readiness required to govern tool registries at scale.
