CAPI Gateway

CAPI Gateway is a lightweight, open-source API Gateway and load balancer powered by Apache Camel dynamic routes. Services register themselves in HashiCorp Consul, and CAPI automatically discovers them, creates routes, and applies security, throttling, and observability policies with no database required. It supports REST, WebSocket, SSE, and gRPC traffic, with built-in OAuth2/OIDC validation, Open Policy Agent authorization, distributed throttling via Hazelcast, and OpenTelemetry tracing. It also features an experimental MCP Gateway that can expose any existing REST API as an MCP tool for LLM agents without requiring code changes on the backend.
