PubNub MCP Server 2025: Features & Setup Guide

Overview

The PubNub MCP Server is a CLI-based implementation of the Model Context Protocol that exposes PubNub SDK documentation and PubNub API resources to large language models and AI tooling. It provides JSON-RPC over STDIN/STDOUT for interacting with PubNub via a suite of tools that fetch official SDK docs in multiple languages (JavaScript, Python, Java, Go, Ruby, Swift, Objective-C, C#, PHP, Rust, Unity, Kotlin, Unreal) and API reference sections (configuration, publish/subscribe, presence, access-manager, channel-groups, storage-and-playback, mobile-push, objects, files, message-actions, misc, functions). It can fetch PubNub Chat SDK docs (JavaScript, Kotlin, Swift, Unity, Unreal) and topics (configuration, chat, channel, user, message, membership, thread-channel, thread-message, message-draft, event, access-control, glossary), plus PubNub conceptual guides from local resources. The server supports publishing messages, subscribing and receiving real-time and historical messages, retrieving presence information, and generating step-by-step instructions for creating PubNub apps (write_pubnub_app) and managing apps/API keys (manage_pubnub_account). It uses environment variables (PUBNUB_PUBLISH_KEY, PUBNUB_SUBSCRIBE_KEY), SSE transport (HTTP_PORT), and a Chat SDK mode for focused Chat SDK resources. Web/article content is converted from HTML to Markdown via jsdom and turndown; input validation uses Zod; and tooling is built on the MCP SDK for extensibility, suitable for Cursor IDE integration.
