## MCP tools (7)

### `trigger_event` (~104 tokens)

Send an event to one or more Pusher channels. Use this to push realtime messages to connected clients.

Input parameters:

- `channel` (required): Channel name or array of channel names (max 100)
- `data` (required): Event payload — string or JSON object (max 10KB)
- `event` (string, required): Event name to trigger (e.g. 'new-message', 'update')
- `socketId` (string): Optional socket ID to exclude from receiving the event (prevents echo)

### `trigger_batch_events` (~51 tokens)

Send up to 10 events in a single API call. More efficient than triggering events individually when you need to notify multiple channels.

Input parameters:

- `events` (array, required): Array of events to send (max 10)

### `list_channels` (~78 tokens)

List all active channels in your Pusher app. Optionally filter by prefix (e.g. 'presence-' or 'private-') and request subscription or user counts.

Input parameters:

- `info` (array): Additional attributes to include for each channel
- `prefix` (string): Filter channels by prefix (e.g. 'presence-', 'private-chat-')

### `get_channel_info` (~53 tokens)

Get detailed information about a specific Pusher channel, including whether it is occupied and optional subscription/user counts.

Input parameters:

- `channel` (string, required): The channel name to query
- `info` (array): Additional attributes to request

### `get_presence_users` (~47 tokens)

List all users currently connected to a presence channel. Only works with channels that start with 'presence-'.

Input parameters:

- `channel` (string, required): Presence channel name (must start with 'presence-')

### `authorize_channel` (~85 tokens)

Generate an authorization token for a private or presence channel. Useful when building auth endpoints for Pusher client connections.

Input parameters:

- `channel` (string, required): Private or presence channel name (must start with 'private-' or 'presence-')
- `presenceData` (object): Required for presence channels — identifies the connecting user
- `socketId` (string, required): The socket ID from the client connection

### `terminate_user_connections` (~47 tokens)

Disconnect all connections for a specific user. Useful for moderation or security — forces a user offline across all channels.

Input parameters:

- `userId` (string, required): The user ID to disconnect from all channels
