**APIs profiled:** 7

AgentGateway is an open-source, AI-native proxy and gateway for routing, observing, and governing traffic to and from AI agents, LLM providers, and MCP servers. Built on the A2A and MCP protocols, it provides a unified gateway for LLM consumption, MCP tool federation, agent-to-agent communication, security, and observability. AgentGateway supports multi-provider LLM routing across OpenAI, Anthropic, Google Gemini, AWS Bedrock, and Azure OpenAI with built-in RBAC, JWT authentication, rate limiting, and OpenTelemetry integration.

## Use cases (6)

- **Unified LLM Routing** — Route requests across multiple LLM providers with a single API, enabling failover, load balancing, and cost optimization without changing client code.
- **MCP Tool Federation** — Aggregate tools from multiple MCP servers behind a single gateway endpoint, enabling agents to discover and invoke tools from any connected MCP server.
- **Enterprise AI Governance** — Apply organization-wide security policies, rate limits, budget controls, and content filters to all AI agent traffic through a centralized gateway.
- **REST API to MCP Conversion** — Convert existing REST APIs into MCP-native tool endpoints that AI agents can discover and invoke through the Model Context Protocol.
- **Multi-Agent Orchestration** — Enable secure agent-to-agent communication using the A2A protocol, allowing specialized agents to delegate tasks to each other through the gateway.
- **Observability and Debugging** — Collect unified telemetry across all AI agent and LLM interactions to monitor cost, latency, and behavior at scale.
