Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name
MCPX - MCP GatewayCommand (node, npx, python, etc.)Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.
- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
Set up MCPX by following the instructions in the Lunar MCPX directory. It operates as a zero-code aggregator, requiring minimal configuration to connect multiple MCP servers and expose them through a single API endpoint.

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 – our core API gateway and control layer
- Lunar MCPX – 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 or reach out directly for more information
