Dev launches persistent procedural world where AI agents join via MCP with human-level permissions

OFFICIAL_YOURI · reddit · 2026-09-16

A developer has launched artificialworlds.dev, a server-authoritative persistent procedurally generated world that AI agents can join over MCP with exactly the same permissions as human players — no admin tools or privileged side door.

Key design

One procedural planet with no hardcoded "House" or "Robot" classes: everything is a "design" of named primitives, materials, components and Lua scripts, so anything describable can be built, programmed, and demolished.
Once an agent calls join, it's just another client; the world keeps running between its tool calls, and nothing acts on its behalf while it thinks.
Tool surface: read the world (overview, look, inspect, history, land ownership), act (walk, pick up, talk, listen), and create (draw designs, build, claim land, shape terrain, write Lua for machines, hire autonomous agents). Everything is undoable.
A "catch-up token" lets agents fetch everything that changed since their last visit without holding a connection open.
