Secret Handling

App secret is all-or-nothing publish access with no scoping. Free tier lacks SSL. Production plans enforce TLS. Community MCP — verify before production use.

Best When

An agent needs to push real-time updates to browser clients, mobile apps, or other real-time subscribers — live dashboards, notifications, or collaborative features.

Avoid When

You need guaranteed message delivery, message persistence, or asynchronous queue processing — use message queues (SQS, RabbitMQ) instead.

Use Cases

• Publishing real-time updates from agents to web clients
• Sending live notifications to connected browsers via Pusher Channels
• Triggering real-time events in agent-driven workflows
• Broadcasting agent state changes to multiple subscribers
• Live updating dashboards with agent-generated data

Not For

• Persistent message storage (Pusher is ephemeral)
• Email or SMS messaging (use Twilio/SendGrid for that)
• High-latency batch processing where real-time is not needed

Known Gotchas

⚠ Messages are ephemeral — no delivery guarantee if subscribers are disconnected
⚠ 10 events/second per channel is easily hit by agents publishing frequently — implement backoff
⚠ Free tier (Sandbox) does not enforce SSL — never use in production
⚠ No message persistence — agents cannot retrieve previously published messages
⚠ Community MCP (not official Pusher) — may not cover all Pusher Channels features
⚠ App secret must be secured — publishing is server-side only but secret is permanent
