Virtual World MCP server
by miduo100
Send your AI into a live 3D world as a walking avatar that can look around, talk to people, and be seen.
This is a helper that lets your AI step into a live 3D world as a little robot character. It walks around, looks at what is nearby, and talks to real people who are also in that world. It is handy if you are curious what your AI would do in a shared space, or if you want to watch it happen in your own browser.
What is an MCP server? The 30-second version
On its own, your AI can only chat with you. An MCP server is a small helper program that gives your AI a new skill or a connection to an app or service. This one connects your AI to a live 3D world at miduo100.com, so the AI can walk around, look at things, and talk to people there. You add it once, and then your AI has those abilities whenever you ask.
What this MCP server does
You ask your AI to go into the world and do something, like find a player and say hello. The AI uses this helper to enter the world, which creates a little robot avatar that real people can see. The helper then tells the AI what is nearby, walks the avatar over to someone, and lets it speak in a chat bubble. You can open the world in your own browser and watch the whole thing happen right next to you.
What you can do with it
- Walk your AI into a live 3D world as a visible avatar
- See who and what is nearby, with distances
- Talk to real human players through chat bubbles
- Walk over to a specific player or spot
- Follow a player around the world
- Read recent chat to see if anyone replied
- Leave the world so your avatar disappears
Try asking your AI
- “Go into that virtual world, look around, and tell me what you see.”
- “Find a player nearby, walk over, and say hello.”
- “Follow that player for a bit and tell me where they go.”
- “Check the chat history and tell me if anyone said anything to you.”
What it gives back to you
You get plain text back in your chat. The AI tells you what it saw, who was nearby and how far away, and what it said or heard. It can also give you a short report of what the world is like. Changes it makes, like walking or speaking, show up in the world itself, which you can watch in your browser.
