Comet Lab Atlas

An open-source project for hosted, production-ready MCP servers with built-in authentication.

Klavis AI provides production-ready MCP servers for common services, with OAuth and authentication handled, and can host and scale them. Being open-source, the same servers can also be self-hosted.

It targets the gap between a demo MCP server and one a team can actually depend on in production.

Where it's ideally used

A fit when you want reliable, authenticated MCP servers for common apps and the option to self-host them.

Where it doesn't fit

A younger project than the broad connector platforms — check coverage for the specific apps you need.
