# Welcome to Lunar.dev **Lunar.dev** is an open-source platform for **managing, governing and optimizing** third-party API consumption across applications and AI agent workloads at scale.

## Consumption Management for the AI Era As AI agents and autonomous workflows increasingly rely on external APIs, there's a growing need for a mediation layer that acts as a central aggregation point between applications, agents, and the services they depend on. Lunar.dev provides that layer—serving as a unified API Gateway for AI, delivering: - **Live API Traffic Visibility:** Get real-time metrics on latency, errors, cost, and token usage across all outbound traffic, including LLM and agent calls. - **AI-Aware Policy Enforcement:** Control tool access, throttle agent actions, and govern agentic traffic with fine-grained rules. - **Advanced Traffic Shaping:** Apply rate limits, retries, priority queues, and circuit breakers to manage load and ensure reliability. - **Cost & Performance Optimization:** Identify waste, smooth traffic peaks, and reduce overuse of costly APIs through smart gateway policies. - **Centralized MCP Aggregation:** Streamline operations by consolidating multiple MCP servers into a single gateway, enhancing security, observability, and management. ## Choose Your Path Lunar.dev is composed of two major components: - [**Lunar Proxy**](https://github.com/TheLunarCompany/lunar/tree/main/proxy#readme) – our core API gateway and control layer - [**Lunar MCPX**](https://github.com/TheLunarCompany/lunar/tree/main/mcpx#readme) – a zero-code aggregator for multiple MCP servers with unified API access Explore the one that fits your needs—or use both for a full-stack solution. ## Open Source at the Core This project was born out of the need for a more robust, production-ready approach to managing third-party APIs. It remains open-source at its core and free for non-production/personal use. For production environments, we offer advanced features through guided onboarding and platform tiers; [visit our website](https://lunar.dev) or reach out directly for more information29:T632,## What is Lunar.dev? Lunar.dev is an open-source platform designed for managing, governing, and optimizing third-party API consumption across applications and AI agent workloads at scale. ## How to use Lunar.dev? To use Lunar.dev, integrate it as a unified API Gateway in your applications to manage API traffic, enforce policies, and optimize performance. You can choose between the Lunar Proxy for core API management or Lunar MCPX for zero-code aggregation of multiple MCP servers. ## Key features of Lunar.dev? - Live API Traffic Visibility: Real-time metrics on latency, errors, cost, and token usage. - AI-Aware Policy Enforcement: Control access and govern agent traffic with fine-grained rules. - Advanced Traffic Shaping: Apply rate limits, retries, and priority queues for reliability. - Cost & Performance Optimization: Identify
