AI orchestration is the layer that routes and governs AI traffic across model providers, MCP servers, agents, and downstream tools. It covers LLM gateways handling multi-provider routing and failover, MCP gateways brokering tool calls, and the agent-level orchestration that composes several agents into one workflow.

Why is AI orchestration important?
AI orchestration matters because it is the chokepoint where AI traffic actually composes, which makes it the only place inline policy can be enforced consistently across providers and agents. Enforce at the model and you cover one provider. Enforce at the application and you cover one application. Enforce at the orchestration layer and you cover everything routed through it.
This is also where organizations most often end up doing the work twice. A platform team selects an LLM gateway for cost optimization and multi-provider failover, security is not consulted, and eighteen months later the same team is retrofitting policy enforcement and data controls onto a component chosen on entirely different criteria.
The conclusion worth carrying into a procurement conversation is that the orchestration layer is an AI security decision regardless of who originally chose the tool. Gartner expects 40% of enterprise applications to carry task-specific AI agents by the end of 2026, so the volume passing through that layer is heading in one direction.
What is AI orchestration?
AI orchestration is the coordination layer sitting between the systems that request AI work and the providers, tools, and agents that perform it. Every request passes through it, which is what allows routing and policy enforcement to happen in one place rather than being reimplemented per application.
It operates at three levels. An LLM gateway brokers traffic to model providers, handling routing by cost, latency, or capability, with failover and per-request attribution alongside. An MCP gateway brokers tool calls, sitting between agents and the MCP servers they reach so each invocation can be logged and evaluated. Agent-level orchestration composes multiple agents into a workflow, sequencing them and managing what passes between them.
Orchestration is not the same as a control plane. A gateway routes and enforces on traffic reaching it. A control plane owns the inventory, the posture, and the policy that orchestration enforces, which is why orchestration is best understood as one function within it rather than a substitute for it.
Types of AI orchestration
The three levels in the definition are the primary taxonomy, and each answers a different operational need.
LLM gateways address provider management. They route across model providers, fail over when one degrades, attribute spend per request, and give a single place to apply rate limits and content policy. Organizations typically adopt one for cost and reliability, then discover it is the natural enforcement point.
MCP gateways address tool access. They broker calls between agents and MCP servers, which is the only place a tool invocation can be inspected before it executes. As agents gain tool access this becomes the higher-risk layer of the two.
Agent orchestration addresses workflow. It sequences agents and manages the handoffs between them, which introduces coordination risk that neither gateway sees – an individually permitted action can be part of a sequence that should not have been allowed.
AI orchestration & Onyx
AI orchestration is one of the five pillars of the Onyx Secure AI Control Plane. The Onyx AI Gateway provides centralized routing, policy enforcement, and queryable per-request audit for LLM and agent traffic, with multi-provider routing and inline policy enforcement.
Teams that have already standardized on a gateway do not have to replace it, since bring-your-own configurations including LiteLLM and similar are supported. The MCP gateway and agent-level orchestration sit alongside in the same control plane, on the same inventory and policy layer, which is what avoids the usual outcome of routing decisions living in one system and enforcement decisions living in another. AI Orchestration and MCP security are two views of the same traffic.
