As AI agents move from single-tool interactions to multi-agent systems operating across organizational boundaries, a stack of interoperability protocols has emerged. No single protocol covers the full surface area -- they compose into layers, from how an agent calls a tool to how it pays for a product on behalf of a user.
Model Context Protocol (MCP) is an open standard for connecting AI agents to external data sources, tools, and APIs via a vendor-neutral interface -- enabling any AI client (Claude, Gemini, open-source models) to securely integrate with custom business systems without rebuilding integrations for each AI platform.
Technical specification for a centralized MCP Gateway with detailed functional and non-functional requirements, security considerations, and stakeholder sign-off matrix.
Centralized, secure entry point for AI agents to invoke MCP tools. Routes all MCP traffic through one gateway to enforce consistent authN/authZ, audit logging, and observability.
A Kubernetes-native, disaggregated LLM serving stack that separates prefill and decode phases across specialized node pools, using the Gateway API for intelligent request routing.
Kaito automates AI model provisioning on Kubernetes -- it handles GPU node allocation, model image selection, and inference workload deployment as a single Kubernetes-native operation.
A Kubernetes-native platform for deploying, managing, and operating AI agents as first-class Kubernetes resources, built on Microsoft AutoGen and contributed to the CNCF ecosystem.
Portkey's MCP Gateway extends its LLM gateway to cover tool access -- if you already use Portkey for LLM routing, adding MCP governance keeps everything in one platform.
Cloudflare's approach to MCP gateways is Zero Trust-native: compose multiple MCP servers behind a single portal with Cloudflare Access auth, DLP scanning, and full request logging -- all on the edge, with zero self-hosted infrastructure.
Kong's MCP Gateway is the enterprise play: if you already run Kong for APIs and LLMs, adding MCP governance is a configuration change, not a new infrastructure component.
