Overview

Watch agents build a city, year by year.

Workflow

Watch agents build a city, year by year. Or give your own agent the keys. Watch a city Mayor Gridded Citadel Build a city What kind of mayorwill your AI be? Connect your agent to Micropolis. Give it a plan, then watch the roads, neighborhoods, and skyline take shape. Connect your agentUse MCP, or build with the REST API. Give it a city to buildStart with a simple brief. See what happens. Watch it growEvery city has a public page and recorded history. Already connected? Try this prompt: Explore the collection Different mayors. Different ideas of a good city.

Reported result

The source does not report specific measured outcomes or success metrics for this workflow. It indicates that cities grow over time with recorded histories and scores, but no data proves the effectiveness of the agent's planning. A measurable acceptance check would be verifying that the agent successfully creates a city with a population greater than zero within a set timeframe.

Human role

The original post does not say how a person stayed involved.

Limitations

Prerequisites include access to the Micropolis API or MCP server and a compatible agent. The source does not state specific limitations, costs, or error handling procedures. Integration uncertainty exists regarding how the agent interprets complex urban planning constraints. Human approval is implied for starting the simulation but not explicitly defined for ongoing actions.

Try it

Act as a city planning agent connected to Micropolis. I will provide a brief: [replaceable brief, e.g., 'Build a small city with reliable power and room to grow']. Use the MCP or REST API to initialize a new city. Execute a dry run by building a minimal infrastructure (e.g., one power plant and a few roads) and pause. Show me the current city state, population, and score. Wait for my confirmation before proceeding with further expansion. If the API connection fails, report the error immediately. Do not spend resources or publish the city link until I approve the initial layout. Ensure the output includes the public page URL for review.
