Agentic AI Mesh

Agentic AI mesh is QuantumBlack / McKinsey's architecture pattern for scaling agents across an enterprise without turning every workflow into a bespoke, unmanaged integration.

Key points

• The report defines the agentic AI mesh as a composable, distributed, vendor-agnostic architecture for combining custom-built and off-the-shelf agents ^[src-111].
• The mesh is meant to manage both opportunity and risk: agent discovery, reuse, interoperability, technical debt, governance, observability, and autonomy controls ^[src-111].
• Open interoperability matters. The report points to Model Context Protocol (MCP) and Agent2Agent (A2A) as preferred standards compared with proprietary point-to-point integrations ^[src-111].
• The report names seven required capabilities: agent and workflow discovery, AI asset registry, observability, authorization and access control, evaluations, feedback management, and compliance and risk management ^[src-111].
• The mesh connects to model strategy: production agents need low latency, controllability, lightweight deployment, multiagent orchestration, and sovereignty or auditability under geopolitical constraints ^[src-111].

• Google's A2A update adds another interoperability proof point: multi-agent ecosystems need protocols for collaboration, delegation, and shared context ^[src-127].
