Add this endpoint the same way as any other MCP server in your client. It needs no sign-in and no API key, and it offers one tool, growsurf_create_account. Your assistant asks for your business email, shows you the Terms of Service and Privacy Policy for approval, and creates the account. Verify the email GrowSurf sends you, then connect to https://mcp.growsurf.com for everything else.
