LightNow is a registry for public and private Model Context Protocol (MCP) servers. It provides a publicly accessible catalog with verified publishers and a tenant-capable private registry. LightNow is fully compatible with the official MCP Registry and additionally exposes MCP server capabilities (tools, resources, prompts). Server manifests can be validated and published.

LightNow includes multi-layer trust scoring per server version as well as ownership verification. The registry is designed for enterprise use cases, including SSO/IdP integration, custom branding, and governance policies. Technically, it is built on an event-driven architecture and runs on Kubernetes, with AI-assisted category assignment.
