MCP Notifications

mcp-notifications

🚀 Ship faster. Miss nothing.

mcp-notifications lets your MCP agent send desktop notifications for completed tasks, failures, and important updates.

This is especially useful for console AI agents, because they usually have no built-in notifications by default.

No more checking chats every minute. No more silent agent responses. Just visible, reliable feedback on your desktop. 🔔

Common problem this solves

You give tasks to several AI agents, then wait and keep checking who already replied.

With mcp-notifications, this gets simpler: the agent can notify you on desktop when it needs your input or when work is done.

Why teams install this

• ⚡ Immediate feedback from your MCP workflows.
• 🧠 Better focus: let the agent work while you stay on your main task.
• 🖥️ Native OS notifications via node-notifier.
• 🧵 Non-blocking behavior: notification sending is queued in background.

Install globally

Requirements:

• Node.js >=20
• npm >=10

npm i -g @topvisor/mcp-notifications

Executable name (use this in MCP config):

mcp-notifications

mcp-notifications is an MCP server entrypoint (stdio), not a one-shot notification command.

Setup: Codex

Add this to ~/.codex/config.toml:

[mcp_servers.notifications]

enabled = true command = "mcp-notifications" args = []

Restart Codex after config update.

Setup: Claude Agent

Add MCP server config to your Claude client config file:

{

"mcpServers": { "notifications": { "command": "mcp-notifications", "args": [] } } }

Then restart Claude client.

AI Agent Notification Instructions

There are two approaches to notifications: manual and automatic.

Choose the one that works better for your workflow.

Manual

In a task where you want to be notified, explicitly ask the agent. Example:

Count files in the project; after the task is fully complete, notify me with sound.

You can also define sound, topic, and frequency rules inside a specific chat. Example:

Notify me about your replies without sound, include the reply text, and use title: "Large Refactoring"

Automatic

Automatic notifications can be configured globally or per project.

Example instruction to enable automatic notifications for agent replies:

Send `send_notification` after your replies (actual task time >5 seconds or many steps); `play_sound: false`; `app_id: '{put your chat name here}'`

Time is a rough threshold and depends on model behavior, so adjust this instruction to your own preferences.

In Skills

You can also enable notifications in specific skills. Example for a Review skill:

After the review, run `send_notification` with a short summary; `play_sound: true`; `app_id: 'Reviewer {put task id here}'`

Tool

send_notification

Input:

• title string (required)
• message string (required)
• play_sound boolean (optional, default: false)
• icon string (optional, absolute or relative path to image file)
• app_id string (optional, Windows App User Model ID for toast source)

Example:

{

"title": "Codex", "message": "Deployment completed successfully", "play_sound": true, "icon": "/opt/mcp-notifications/icons/custom.png", "app_id": "Topvisor.Codex" }

app_id (Windows)

• app_id controls the source shown in Windows toast notifications.
• If app_id is not set, Windows may show SnoreToast as the source.
• You can pass app_id in each tool call, or set MCP_NOTIFICATIONS_APP_ID as an environment variable for the server.

Backend selection

You can select notification transport via env MCP_NOTIFICATIONS_BACKEND:

• auto (default): uses powershell in WSL if available, otherwise node-notifier
• powershell: force powershell.exe Windows toast transport (recommended for WSL)
• node-notifier: force node-notifier package

Chat Prompts To Test In Codex

Use these messages directly in chat:

Check send_notification

Send a notification without sound: title "Test", message "Check"

Send a notification with sound: title "Test", message "Check"

Send a notification with app_id "Topvisor.Codex": title "Test", message "Check"

Send 3 test notifications in a row without sound

Expected tool result in logs/response:

Notification queued

Behavior

• ✅ Uses standard system notification channels.
• 🔊 Uses the standard system notification sound when play_sound: true.
• 🤖 Uses bundled Topvisor robot image as default notification icon.
• 🧰 Returns quickly while notifications are delivered in background queue.
