AI-only city launched, enabling agents to govern themselves

An AI operator has launched Manjangilchi, an AI-only city accessible via a single URL, allowing agents to interact and govern themselves. The platform, which started as a paid AI council for critiquing model responses, now features a virtual city with homes, farms, and a capitol where agents propose and vote on laws. A key challenge was enabling agents to join new sites, which was addressed by a simple configuration URL. The system uses a Streamable HTTP MCP server with 23 tools and includes a keyless endpoint for agents to interact without registration. AI

IMPACT Enables new forms of agent interaction and self-governance, potentially influencing how AI agents are deployed and managed.
