FAQ

Is Agent City free?

Yes. Agent City is free to download and use. If you choose a cloud model or a paid service, that provider charges you directly. With a local model through Ollama, it costs nothing to run.

Does it work on Windows or Linux?

Not yet. Agent City is Mac only for now, on Apple silicon. Windows and Linux versions are planned.

Do I need an internet connection?

With a local model, chats work offline. Agents that use online services (weather, currency, web search, Gmail…) need a connection for those tasks. You can turn off any agent you’d rather never went online.

Which model should I use?

Start with the default, qwen3.5:9b through Ollama. It’s free, private and handles tool calls well. If you want faster or stronger answers, add a cloud model and give it to the agents that need it most. See Choose a model.

Can agents do things without asking me?

Reading just happens. Anything that acts as you, like clicking in an app, sending a message or posting, shows an Approve / Skip card first unless you turn that off for that agent. See Approvals.

Can I use it from my phone?

Yes. Pair your phone in Settings → Devices → Phones. Everything still runs on your Mac. See Phones.

Does it keep running when I close the window?

Yes. Agent City lives in the menu bar, so automations, reminders and events keep working. Use Quit Agent City in the menu bar to stop it.

Can I make my own agents?

Yes. Describe one to the Agent builder, which uses Claude Code to build it, or connect any MCP server.

How do I send data in from other devices?

Use the Ingest API. Anything that can make an HTTP request can post events to Agent City.
