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.

FAQ

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 Pydantic AI discover MCP tools?

Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.

Does Pydantic AI validate MCP tool responses?

Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.

Can I switch LLM providers without changing MCP code?

Absolutely. Pydantic AI abstracts the model layer. your PubNub (Real-time Messaging) MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
