Agentgateway is an open source proxy built on MCP and A2A protocols for routing and securing agent-to-LLM, agent-to-tool, and agent-to-agent communication.

It provides LLM provider routing, MCP tool federation, A2A agent collaboration, self-hosted model inference routing, and multi-layered content guardrails. The project supports standalone and Kubernetes deployments with JWT/OAuth authentication, RBAC, rate limiting, and OpenTelemetry observability.
