+### Agent Gateway (with Kgateway)
+[![Conformance](https://img.shields.io/badge/Gateway%20API%20Conformance%20v1.3.0-Agentgateway-green)](https://github.com/kubernetes-sigs/gateway-api/blob/main/conformance/reports/v1.3.0/airlock-microgateway)
+
+[Agent Gateway](https://agentgateway.dev/) is an open source Gateway API implementation focusing on AI use cases, including LLM consumption, LLM serving, agent-to-agent ([A2A](https://a2aproject.github.io/A2A/latest/)), and agent-to-tool ([MCP](https://modelcontextprotocol.io/introduction)). It is the first and only proxy designed specifically for the Kubernetes Gateway API, powered by a high performance and scalable Rust dataplane implementation.
