Lunar API Gateway

Example Use Cases

• 1

  Centralized observability of outbound API traffic (latency, errors, cost, and token usage) across LLM and other API calls.

• 2

  AI-aware policy enforcement to control tool access, throttle actions, and apply fine-grained governance rules.

• 3

  Traffic shaping and reliability controls like rate limits, retries, priority queues, and circuit breakers to optimize cost and performance.

Description

Lunar.dev provides a mediation layer (Lunar Proxy and Lunar MCPX) that centralizes outbound API traffic, offering real-time visibility, AI-aware policy enforcement, advanced traffic shaping, and cost/performance optimization. It helps control agent tool access, apply rate limits, retries, priority queues, and circuit breakers, and aggregates multiple MCP servers into a single unified gateway. The platform is open-source at its core and is free for non-production/personal use while offering production-focused features and platform tiers through guided onboarding.
