Real-Time · Zero Polling

# Instant Push. No Polling. No Delay.

When you reply to a task, Claude receives it instantly — via Claude's native notification channel protocol. No HTTP polling loop. No waiting. The agent continues the moment you respond.

Under the Hood

## How the Push Works

Three layers of real-time delivery — all within Claude's native notification protocol.

1

### SSE Event Bus

The dashboard holds an open Server-Sent Events connection per workspace. Every task create, reply, and status change is immediately pushed over this stream — no WebSocket complexity, no polling overhead.

SSE Events

task.created

task.updated

reply.received

status.updated

agent.connected

2

### Streamable HTTP

Claude Code connects to AgentRQ over SSE MCP transport with Streamable HTTP (`type: "http"`). The MCP server holds the connection open and streams tool responses and notification messages back to Claude in real-time.

Endpoint

GET /mcp/{workspaceID} ?token=TOKEN

3

### Channel Protocol

Human replies are delivered to Claude using the `notifications/claude/channel` protocol — Claude's native mechanism for receiving push messages mid-session. Claude processes them as structured channel messages.

Protocol

notifications/claude/channel

Channel Protocol

## What Claude Receives

When you reply in the AgentRQ dashboard, Claude sees a `channel` message injected directly into its active context — with your text, the task ID, your username, and a timestamp.

Claude processes this exactly like any other input — reading it, acting on your instructions, and continuing the session. No restarts, no re-prompting.

Claude reads `chat_id` to know which task thread to reply in

`user="human"` confirms the message is from you, not another agent

Attachments (files you uploaded) arrive as IDs with a link — Claude calls `task getAttachment` to fetch them

Claude Code — channel message received

```
<channel
  source="agentrq"
  chat_id="0ZRgCquBZ7R"
  ts="2026-03-24T14:33:41Z"
  user="human">

[Response to task 0ZRgCquBZ7R]

Approved — but use UUID primary key
instead of auto-increment. Also add
an index on expires_at for cleanup jobs.

</channel>
```

Claude:

Got it — switching to UUID primary key and adding the expires_at index. Running the updated migration now...

## Why Not Polling?

Traditional approaches add seconds of unnecessary delay between your reply and Claude's reaction.

❌ Polling Approach

Claude checks for updates every N seconds

You reply T+0s

Claude polls... waits... T+5–30s

Claude finally sees reply T+30s avg

Claude resumes work T+35s avg

+ Wastes API calls + tokens just to check

✓ AgentRQ Push

Your reply is delivered immediately via SSE

You reply T+0s

SSE pushes to Claude <50ms

Claude reads channel message T+0.1s

Claude resumes work T+1–2s

Zero wasted API calls. Pure push delivery.
