PubNub MCP Server

A hosted Model Context Protocol (MCP) server that exposes PubNub SDK documentation and PubNub API resources to LLM-powered tools. This improves the LLM AI Agent's ability to understand and interact with PubNub's SDKs and APIs. Uses HTTP transport with OAuth authentication. Its 15 documented tools cover pubnub, manage, sdk, documentation. It runs locally over stdio via the published package.

People connecting this server to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install PubNub MCP Server

before you install - you'll need

PUBNUB_API_KEY

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add pubnub-pubnub-mcp-server -- npx -y @pubnub/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "pubnub-pubnub-mcp-server": {
      "command": "npx",
      "args": [
        "-y",
        "@pubnub/mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
