PubNub MCP Server

The PubNub MCP Server enables AI agents to interact with PubNub's real-time infrastructure. It allows agents to fetch documentation, execute live API calls like publish and fetchHistory, and manage presence data. Designed for IDEs like Cursor and Claude, it streamlines the integration of real-time features such as chat, dashboards, and IoT alerts by providing direct access to SDKs and APIs.
