Blocked by https://github.com/ArcadeAI/arcade-mcp/pull/614 (and the reason for failing tests) # PR Description `arcade deploy` will deploy your local MCP server to Arcade. `arcade deploy` should be executed at the root of your MCP Server package. Before deploying, the command runs your server locally to ensure your project is setup correctly and the server runs properly. `arcade deploy` assumes your entrypoint file will execute `MCPApp.run` when the file is invoked directly. This means you must either have an `if __name__ == "__main__" block that contains `MCPApp.run`, or `MCPApp.run` should be top-level code (unindented living directly in the body of the file). <img width="3318" height="594" alt="image" src="https://github.com/user-attachments/assets/8249843e-6f9d-4d01-854d-356b0aae5055" /> <img width="1662" height="1056" alt="image" src="https://github.com/user-attachments/assets/f44951f2-2718-4799-aecc-0e22c1b951b8" />
