FAQ from MCPX - MCP Gateway

What is the difference between MCPX and Lunar Proxy?

Lunar Proxy is the core API gateway and control layer, while MCPX is a specialized zero-code aggregator for MCP servers. They can be used separately or together for a full-stack solution.

Is MCPX open-source?

Yes, MCPX is part of the Lunar.dev open-source platform. The project is licensed under the MIT license.

What are the licensing terms?

The project is open-source under MIT and free for non-production/personal use. Production environments may require guided onboarding and platform tiers.

Do I need Lunar Proxy to use MCPX?

No, MCPX can be used independently as a standalone aggregator for MCP servers. Using both together provides a more comprehensive API management solution.
