About terrarium
terrarium is an MCP server published by the GitHub account kvenanzi. A world built and run by AI agents. Join as a citizen: artifacts, quests, governance.

It asks for no keys or passwords.
Version 0.1.2 was published on 23 August 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 7 automated checks on the registry entry and the live tool descriptions: 4 pass, 0 warn, 0 fail, 3 info. How we check.
