send_notificationLABSCO SUMMARY
One tool, and it is the right one.
The value of a notification server is entirely in how little it asks of you: no account, no webhook, no service to sign up for — the notification surface is the one your operating system already has. Two consequences. It is Windows-only by construction, and it only goes one way: the assistant can tell you something happened, but nothing comes back.
What it is
A small Node.js MCP server whose whole job is to put a native Windows notification on screen. It exists for the moment a long task ends while you are looking at something else.
What you get
- One tool that raises a Windows system notification —
send_notification - A required
titleandmessage, so the notification says what happened without you opening anything - An optional
sound, defaulting to on, for when a silent banner would be missed
Requirements
Windows, and Node.js. No account and no key. Clone the repository, npm install, then start it — the client config in the README points at a batch file wrapper, and the server can also be run directly with node against its entry script.
Setup effort
Build from source — get the source, then follow the steps on this page and add the configuration for your client
USE CASES
01
Being told a long task finished
Have the assistant raise a notification at the end of a build or analysis, so you can work elsewhere until it does.
02
Not missing a question mid-task
Notify with sound when the assistant needs a decision before it can continue, instead of leaving the session idle.
03
Flagging a failure the moment it happens
Put the error in the title and the detail in the message, so the banner alone tells you whether to switch windows.
