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`.

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).
