Agentic infrastructure must coordinate heterogeneous tools and models through shared enterprise services rather than another layer of point solutions. This matters now because decentralized agent adoption creates duplicated connectors, inconsistent controls, and brittle dependencies across systems of record.
McKinsey describes an agentic mesh built on reusable data assets and common technical standards. The article frames infrastructure as something enterprises redesign both for agents and with agentic automation. The mechanism is a shared mesh that provides context, integration, identity, policy, observability, and deployment paths while allowing different teams to use different agent-building tools.
Platform teams should define golden paths and common contracts while keeping the build layer open enough to avoid one-vendor lock-in. The evidence is McKinsey's proposed architecture and case framing, not independent proof that a particular mesh design is optimal. Watch for implementations that demonstrate portability, cross-platform traces, policy enforcement, and recoverable failure handling.
