Building real-time features fast with the PubNub MCP: Eric Lake

Eric Lake, a Senior Solutions Architect at PubNub, describes using the company’s MCP server to accelerate development of real-time application features, particularly prototypes and customer demonstrations. He built a livestream chat system in about an hour that uses PubNub Illuminate to grant VIP-room access to highly engaged users and revoke access from repeat offenders identified by AI moderation. Lake says the MCP server applies PubNub documentation and best practices without forcing rigid components or workflows, and its token-efficient design distinguishes it from MCP servers that overwhelm an agent’s context with tools. Beyond generating code, it can configure services such as Illuminate business objects and decision logic, while also serving as a learning aid by providing working implementations that developers can inspect and understand. He views moderation of repeat disruptive behavior as a broadly useful application and recommends using the MCP selectively to explore, prototype, and deliver specific real-time experiences rather than treating it as another always-on development tool.
