What is the PubNub (Real-time Messaging) MCP Server?
Connect your PubNub account to any AI agent to orchestrate real-time communication, monitor user presence, and manage data streams through natural language.
What you can do
- Real-time Messaging — Publish JSON payloads to any channel and retrieve historical message logs with precise timetokens.
- Presence Monitoring — Track who is online (
here_now), see which channels a user is in (where_now), and manage custom presence states. - User & Channel Metadata — Manage App Context by creating and retrieving user profiles, channel metadata, and memberships.
- Message Management — Count messages sent after specific timestamps or purge history for compliance and storage management.
- File Sharing — Generate upload URLs and manage files stored within the PubNub network.
- Admin & Push — Monitor keyset metrics, manage applications, and configure mobile push notifications (APNS/FCM).
How it works
- Subscribe to this server
- Enter your PubNub Subscribe Key, Publish Key, and UUID
- Start streaming data and managing real-time interactions from your MCP-compatible client
Who is this for?
- IoT Developers — Monitor device heartbeats and send control commands via real-time channels.
- Support Teams — Inspect chat history and user presence to provide better live assistance.
- System Architects — Audit channel metadata and monitor keyset metrics directly from the AI interface.

Why teams choose Vinkius for PubNub (Real-time Messaging) in Google ADK
The PubNub (Real-time Messaging) MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 31 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in Google ADK only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

* Every MCP server runs on Vinkius-managed infrastructure inside AWS - a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts optimized for native MCP execution. See our infrastructure
How Vinkius secures
PubNub (Real-time Messaging) for Google ADK

Frequently asked questions
How can I check if a specific user is currently online in a channel?
You can use the presence_here_now tool to see a list of all active UUIDs in a specific channel, or presence_where_now to find all channels a specific UUID is currently subscribed to.
Can the AI retrieve past messages from a channel?
Yes, the get_message_history tool allows the agent to fetch historical messages from one or more channels, including metadata and specific time ranges.
Is it possible to manage user profiles and metadata through this server?
Absolutely. You can use set_user to create or update profiles and get_user to retrieve them. You can also manage channel metadata using set_channel and get_channel.
How does Google ADK connect to MCP servers?
Import the MCP toolset class and pass the server URL. ADK discovers and registers all tools automatically, making them available to your agent's tool-use loop.
Can ADK agents use multiple MCP servers?
Yes. Declare multiple MCP tool providers in your agent configuration. ADK merges all tool schemas and the agent can call tools from any server in a single turn.
Which Gemini models work best with MCP tools?
Gemini 2.0 Flash and Pro models both support function calling required for MCP tools. Flash is recommended for latency-sensitive use cases, Pro for complex reasoning.
