## What it is
Agentgateway is an open-source, Rust-based proxy and gateway for agentic AI traffic, handling LLM provider routing, MCP tool servers, and A2A agent-to-agent communication alongside traditional HTTP, gRPC, and TCP traffic in one data plane. It can run as a standalone binary or as a Kubernetes Gateway API data plane with a built-in control plane, offering security, observability, and cost governance.

## Use cases
- proxy LLM requests to OpenAI, Anthropic, Gemini, and Bedrock through one OpenAI-compatible API
- expose and federate MCP tool servers to AI clients with OAuth and authorization
- secure and observe agent-to-agent (A2A) communication
- enforce LLM spend budgets, rate limits, and prompt guardrails
- load balance and fail over across multiple LLM providers
- route inference requests to self-hosted model pools on Kubernetes
- front regular APIs and microservices with the same gateway used for AI traffic

## When to choose
- you need a single gateway for both traditional service traffic and AI-native protocols (MCP, A2A, LLM providers)
- you run Kubernetes and want Gateway API / Inference Extension integration
- you need enterprise features like mTLS, OIDC, multi-tenancy, and cost attribution for agent workloads
- you want tool federation and policy enforcement in front of MCP servers

## When to avoid
- you only need a simple reverse proxy with no AI-specific routing or policy needs
- you want a lightweight client-side SDK rather than an infrastructure gateway
- your stack has no Kubernetes or container deployment capability and you need a managed SaaS gateway
