Lunar.dev acts as a unified API gateway specifically built for AI agents, providing a mediation layer between autonomous agents and the external services they consume. It offers real-time visibility into LLM calls, agent traffic, latency, errors, and costs. The platform enables AI-aware policy enforcement including tool access control, traffic throttling, and fine-grained governance rules. It centralizes multiple MCP servers into a single gateway, applying rate limits, circuit breakers, retries, and priority queues to manage load and ensure reliability across agentic workflows.
