The <strong>first complete</strong> connectivity solution for Agentic AI.

Agentgateway is an open source proxy built on AI-native protocols (MCP & A2A) that provides drop-in security, observability, and governance for agent-to-LLM, agent-to-tool, and agent-to-agent communication across any framework and environment.

Intro to Agentgateway Video

Key Features

• LLM Gateway

Route traffic to major LLM providers (OpenAI, Anthropic, Gemini, Bedrock, and more) through a unified OpenAI-compatible API with budget and spend controls, prompt enrichment, load balancing, and failover.

• MCP Gateway

Connect LLMs to tools and external data sources via MCP with tool federation, stdio/HTTP/SSE/Streamable HTTP transports, OpenAPI integration, and OAuth authentication.

• A2A Gateway

Enable secure agent-to-agent communication using A2A, with capability discovery, modality negotiation, and task collaboration.

• Inference Routing

Intelligent routing to self-hosted models using Kubernetes Inference Gateway extensions, with decisions based on GPU utilization, KV cache, LoRA adapters, and queue depth.

• Guardrails

Multi-layered content filtering with regex, OpenAI moderation, AWS Bedrock Guardrails, Google Model Armor, and custom webhooks.

• Security & Observability

Auth (JWT, API keys, OAuth), fine-grained RBAC with CEL policy engine, rate limiting, TLS, and OpenTelemetry metrics/logs/tracing.

Getting Started

• Standalone Quickstart — Get started with agentgateway in minutes.
• Kubernetes Quickstart — Deploy on Kubernetes using the built-in controller and Gateway API.
