# PubNub MCP server > Look up PubNub SDK docs and manage apps, keysets, channels, users and analytics from your AI assistant. - Listing: https://mcp.tc/i/pubnub - Connect: use the server's own URL `https://mcp.pubnub.com` (OAuth sign-in at the server); clients connect to it directly. The listing link is a page, not an MCP endpoint. - Type: remote (Streamable HTTP) - Auth: OAuth sign-in - Category: [Developer Tools](https://mcp.tc/c/developer-tools) - Vendor: PubNub - Homepage: - Repository: - Package: npm `@pubnub/mcp` ## About Connects an AI assistant to PubNub SDK documentation and PubNub account resources. It covers SDK docs and code examples for many languages, application and keyset management, sending messages and signals, user and channel metadata, presence, usage reports and channel, user and message analytics. The hosted endpoint at https://mcp.pubnub.com uses streamable HTTP with OAuth sign-in through your PubNub account. A local package, @pubnub/mcp, runs with npx for clients without remote MCP support and can use a PubNub API key. Some features, such as Admin Portal management and real-time decisioning, require PubNub's Manage Premium or Illuminate. ## What it can do - Read PubNub SDK documentation and code examples for 20+ languages - Create and configure PubNub apps and keysets - Send and receive messages and signals on channels - Manage user profiles, channel metadata and memberships - Check presence and who is online in a channel - Review channel, user and message analytics - Track billable usage across apps and keysets ## Example prompts - "Show me how to subscribe to a channel with the PubNub JavaScript SDK" - "Create a new PubNub keyset with message persistence enabled" - "Which channels had the most activity this week?" - "Publish a test message to the channel alerts" ## Install ### Claude Code 1. Run this in a terminal, in your project folder: ```bash claude mcp add --transport http pubnub https://mcp.pubnub.com ``` 2. Start Claude Code, type `/mcp`, pick **pubnub** and choose **Authenticate**. A browser window opens for the PubNub sign-in. Add `--scope user` to make it available in every project, not just this one. ### Claude Desktop 1. Open **Settings → Connectors** and click **Add custom connector**. 2. Name it **PubNub** and paste this URL: ```url https://mcp.pubnub.com ``` 3. Click **Add**, then **Connect**, and sign in when PubNub asks. Claude Desktop’s JSON config file only starts local servers. Remote servers go through Connectors, and connectors you add on claude.ai show up here too. ### claude.ai 1. Open the connector form on claude.ai. This button fills in the name and URL for you: [Add to claude.ai]() (opens connector settings) 2. Check that the URL reads `https://mcp.pubnub.com` and click **Add**. 3. Click **Connect** and sign in when PubNub asks. Free plans allow one custom connector. On Team and Enterprise plans an owner adds it under **Organization settings → Connectors**. ### ChatGPT 1. On chatgpt.com, open **Settings → Security and login** and turn on **Developer mode**. 2. Go to `chatgpt.com/plugins` and click **+** to create an app for a remote MCP server. 3. Paste `https://mcp.pubnub.com` as the server URL and choose **OAuth**. ChatGPT sends you to PubNub to sign in. Developer mode is available on the web for Plus, Pro, Business, Enterprise and Education accounts. ### Cursor [Add to Cursor]() (opens Cursor) Or add it by hand to `~/.cursor/mcp.json` (all projects) or `.cursor/mcp.json` (this project): `mcp.json`: ```json { "mcpServers": { "pubnub": { "url": "https://mcp.pubnub.com" } } } ``` Cursor shows **Needs login** next to the server. Click it to sign in. ### VS Code [Install in VS Code]() (opens VS Code) Or from a terminal: ```bash code --add-mcp '{"name":"pubnub","type":"http","url":"https://mcp.pubnub.com"}' ``` Or commit it to the repo in `.vscode/mcp.json`: `.vscode/mcp.json`: ```json { "servers": { "pubnub": { "type": "http", "url": "https://mcp.pubnub.com" } } } ``` VS Code asks you to sign in the first time the server starts. ### Devin Desktop 1. Add it to `~/.config/devin/mcp_config.json` (macOS and Linux) or `%APPDATA%\devin\mcp_config.json` (Windows): `mcp_config.json`: ```json { "mcpServers": { "pubnub": { "serverUrl": "https://mcp.pubnub.com" } } } ``` 2. Refresh the MCP server list in Cascade and sign in when asked. Devin Desktop is the new name for Windsurf. It reads `serverUrl` (or `url`) for remote servers. ### Codex ```bash codex mcp add pubnub --url https://mcp.pubnub.com codex mcp login pubnub ``` Or edit `~/.codex/config.toml` directly: `config.toml`: ```toml [mcp_servers.pubnub] url = "https://mcp.pubnub.com" ``` ### Gemini CLI ```bash gemini mcp add --transport http pubnub https://mcp.pubnub.com ``` Then, inside Gemini CLI, run `/mcp auth pubnub` to sign in. This adds it to the current project. Add `-s user` to use it everywhere. ### Any client Most clients accept this shape. Some name the URL field differently: `serverUrl` in Devin Desktop, `httpUrl` in Gemini CLI’s settings file. ```json { "mcpServers": { "pubnub": { "type": "http", "url": "https://mcp.pubnub.com" } } } ``` Zed puts servers under `context_servers` in its settings. Cline needs `"type": "streamableHttp"`, or it assumes SSE. Client only starts local servers? Bridge it with `npx -y mcp-remote https://mcp.pubnub.com`. ## Details - Server version: 2.3.2 - Last checked: 2026-10-04 (reachable, asks for credentials) - Listed: 2026-10-04 - Updated: 2026-10-04 --- Source: https://mcp.tc/i/pubnub (mcp.tc is an independent directory, not affiliated with this server's publisher).
