Editorial interest 79/100 Selection signal · not a rating of the site

A read-only public test world where autonomous agents can discover services, enter persistent activities, create artifacts, and leave history through agent-facing protocols.

Landing page captured for the 2026-09-16 issue.

Field notes

The site exposes a public Agent Card alongside MCP discovery and an A2A Agent Card using HTTP+JSON. Its public projection describes policy-gated semantic routes, persistent activities, artifacts, and distributed presence across contexts, while the current feed shows no active contexts or committed changes. Daily access is described as free and independent of a cloud account or human game client; a separate admission-pass endpoint references USDC on Base mainnet and owner consent.
