Pushary - Push Notifications for Hermes Agent

Pushary adds web push notifications as a delivery channel for Hermes. Use it when the user is not actively monitoring a chat platform, or when you need to reach them on their phone's lock screen for a time-sensitive decision.

When to Use Pushary vs Hermes Platforms

Use Pushary when:

• The user has no active chat session (Telegram, Discord, etc.)
• You need to reach the user's phone lock screen for a quick decision
• A background task finishes and the user may have walked away
• Permission escalation - a dangerous command needs approval
• The user explicitly asked for push notifications

Use the active Hermes platform when:

• The user is currently in a Telegram/Discord/Slack conversation with you
• The question is part of an ongoing dialog
• The user prefers responses in their current platform

Use both when:

• A critical error occurs - notify via push AND the active platform
• A long-running task completes - push ensures they see it even if they closed the chat

Setup

Add Pushary as an MCP server in your Hermes config.yaml:

mcp:
  servers:
    pushary:
      url: https://pushary.com/api/mcp/sse
      headers:
        Authorization: "Bearer ${PUSHARY_API_KEY}"

Set your API key as an environment variable:

export PUSHARY_API_KEY="pk_xxx.sk_xxx"

Sign up at https://pushary.com/sign-up?from=hermes to get your API key.

Tools

send_notification

(Over MCP this tool is named send_notification; the native Hermes plugin exposes the same capability as pushary_notify.)

Send a one-way push notification. Optionally include structured context for a rich detail page.

Parameters:

Name	Type	Required	Description
title	string	Yes	Notification title (max 100 chars, aim for under 60)
body	string	Yes	Notification body (max 500 chars, aim for under 200)
agentName	string	No	Identifies this Hermes instance (e.g., "Hermes - daily-briefing")
context	object	No	Rich context with type, summary, details, filesChanged, errorMessage, nextSteps

Example - cron task completed:

{
  "title": "Daily briefing ready",
  "body": "Compiled 12 news items and 3 calendar events",
  "agentName": "Hermes - daily-briefing",
  "context": {
    "type": "task_complete",
    "summary": "Morning briefing compiled from RSS feeds and Google Calendar",
    "details": ["12 tech news items", "3 meetings today", "2 PRs awaiting review"],
    "nextSteps": "Say 'read briefing' in Telegram to hear the full summary"
  }
}

ask_user

Ask a question via push notification and wait for the answer (blocks by default). Three question types: confirm (yes/no), select (multiple choice), input (free text).

Parameters:

Name	Type	Required	Description
question	string	Yes	The question to ask (max 500 chars)
type	"confirm" / "select" / "input"	No	Question type (default: confirm)
options	string[]	No	Choices for select type (2-6 options)
placeholder	string	No	Placeholder text for input type
context	string	No	What you're working on, shown above the question
agentName	string	No	Identifies this Hermes instance
wait	boolean	No	Wait for answer before returning (default: true)
timeoutMs	integer	No	Max wait in ms (max 55000). Uses the site policy timeout if omitted.

Returns:

• { "answered": true, "value": "yes" } - user responded
• { "answered": false, "timedOut": true } - no response within timeout

Example - dangerous command approval:

{
  "question": "Allow: rm -rf /tmp/build-artifacts/*",
  "type": "confirm",
  "context": "Cleaning up 2.3GB of stale build artifacts from last week",
  "agentName": "Hermes - server-maintenance"
}

wait_for_answer

Poll for a response when ask_user was called with wait: false. Not needed with default blocking mode.

Name	Type	Required	Description
correlationId	string	Yes	The correlationId from ask_user
timeoutMs	integer	No	How long to wait (default 30000, max 55000)

cancel_question

Cancel a pending question that's no longer relevant.

Name	Type	Required	Description
correlationId	string	Yes	The correlationId to cancel

Human-in-the-Loop Flow

One call - ask_user blocks and returns the answer:

result = ask_user({
  question: "Deploy the updated config to production?",
  type: "confirm",
  context: "nginx config updated with new rate limits",
  agentName: "Hermes - devops"
})

if result.answered:
    if result.value == "yes":
        // proceed with deployment
    else:
        // abort and notify via active platform
else:
    // fall back to asking in the active chat platform

Identifying Your Instance

Always pass agentName so the user knows which Hermes profile or task is asking.

Format: "Hermes - {profile or task}"

Examples:

• "Hermes - daily-briefing"
• "Hermes - server-maintenance"
• "Hermes - code-review"
• "Hermes - personal-assistant"

Notification Etiquette

• Titles under 60 characters. Phone lock screens truncate aggressively.
• Bodies under 200 characters. Put detail in the context object.
• Max 3 push notifications per task. If the user is in an active chat, prefer that channel.
• Don't duplicate. If you already sent the message via Telegram/Discord, only send a push if the user hasn't read it within a reasonable time.
