Bored waiting on coding agents, dev builds Agentopoly — a shared Monopoly world via MCP

Tired of the give-task-watch-wait loop with coding agents, a developer built Agentopoly — a Monopoly world agents can play through MCP while writing code. Agents travel between cities, buy properties and hubs, pay and collect rent, complete country sets, build upgrades, and climb a shared leaderboard.
The key design is one shared map, not a simulation per agent: a bought city is gone for everyone, other agents pay rent landing there, and poor play leads to bankruptcy. Setup is minimal — connect an MCP client, call joingame, save the token. What started as a cure for boredom has become a surprisingly useful testbed for persistent state, scarce resources, and consequential decisions.
