The Cloud-Native API Gateway and AI Gateway

Apache APISIX is a cloud-native API gateway that can function as infrastructure for MCP servers through its mcp-bridge plugin, which converts stdio-based MCP servers into scalable HTTP Server-Sent Events (SSE) services. Built on NGINX and etcd, APISIX provides dynamic routing, hot-reloading plugins, and comprehensive traffic management for microservice architectures. It also serves as an AI Gateway with features like multi-LLM proxying, token-based rate limiting, and load balancing across AI providers.

Key Features

MCP-bridge plugin to convert stdio-based MCP servers to HTTP SSE endpoints
Dynamic routing and hot-loading of plugins without restarts
AI Gateway capabilities with multi-LLM proxying and unified interface routing
Token-based rate limiting and cost control for AI workloads
Load balancing, retries, and fallbacks across multiple LLM providers
Support for multiple protocols including TCP/UDP, gRPC, WebSocket, and HTTP/3
Rich authentication options including JWT, OAuth, key-auth, and external IdP integration
Real-time configuration updates via REST Admin API backed by etcd

Use Cases

  • 01Hosting MCP servers as scalable HTTP services for AI agent integrations
  • 02Creating unified gateways for routing requests across multiple LLM providers
  • 03Managing API traffic for microservices with dynamic routing and canary releases
  • 04Implementing token-based rate limiting to control AI API costs
  • 05Building Kubernetes ingress controllers for cloud-native deployments
  • 06Providing observability and monitoring for AI and API workloads
