You can play instantly by connecting to the public MCP Game Server using your favorite agent tools—no server setup required!
- Download and install Warp Preview
- Open Warp Preview
- Go to
Settings→Manage MCP servers→+Add - Paste the following into the "SSE endpoint URL" field:
https://mcplayerone.onrender.com/api/v1/mcp/sse - Save and connect!
- You can now interact with the MCP Game Server directly from Warp Preview.
- Install Cursor IDE
- Add the MCP Game Server as a tool server:
- Open Cursor and go to Extensions/Integrations.
- Add a new MCP tool server with this config:
{ "MCPlayerOne": { "transportType": "sse", "url": "https://mcplayerone.onrender.com/api/v1/mcp/sse", "openapi": "https://mcplayerone.onrender.com/api/v1/mcp/openapi.json" } }
- Start playing! Use Cursor's chat or code tools to send MCP commands, automate moves, or analyze game data.
- Install Python and pip
- Install uv:
pip install uv
- Install mcp-proxy:
uvx install mcp-proxy
- Add this to your Claude Desktop config:
{ "mcpServers": { "MCPlayerOne": { "command": "uvx", "args": ["mcp-proxy", "https://mcplayerone.onrender.com/api/v1/mcp/sse"] } } } - Restart Claude Desktop and select the MCPlayerOne server to start playing!
- 404 or connection errors? Make sure you're using the correct Render URL above.
- Agent not responding? Check that you're using the correct SSE endpoint and OpenAPI URL.
- Session timeouts? SSE sessions last for 1 hour of inactivity—just reconnect if needed.
Whether you want to jump right into a game or set up your own server, getting started with MCPlayerOne is easy:
- Use any of the methods above (Warp Preview, Cursor, Claude, etc.) to connect to the public MCP Game Server.
Once connected, tell the agent you would like to play an MCPlayerOne game.
Now, just tell the agent which game you'd like to play and optionally give yourself a username (the agent will choose one for you if you don't).
You can also create and generate your own game to play.
Have fun with it, point it at a website, maybe a GitHub repo, or just give it a theme. The more creative and imaginative you are the more interesting your game. This is where AI generation really shines.
For example, tell the agent something like "Let's create a new MCPlayerOne game, use github https://github.com/SonicDMG/mcp-game-server for the theme" or "Create a new MCPlayerOne game with a theme based on DOOM playing as a space marine".
Game creation takes about 2-3 minutes so please be patient.
