With 31 tools connected to real PubNub data, your agents reason over live information, cross-reference it with other MCP servers, and deliver insights you would spend hours assembling manually.

Works with Claude, ChatGPT, Cursor, and any MCP-compatible client. Powered by Vinkius — your credentials never touch the AI model, every request is auditable. Connect in under two minutes.

Frequently asked questions about the PubNub (Real-time Messaging) MCP Server

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.
