mcping

Let MCP servers ping you

mcping is a daemon that connects to one or more MCP servers over Streamable HTTP and surfaces the notifications they send you.

Available on macOS only, for now.

Usage

Download the app from the latest release, drag it to your Applications folder, open it, and connect to your favorite MCP servers.

Note

mcping isn't notarized by Apple, so on first launch macOS may say it's "damaged and can't be opened." It isn't — macOS just quarantines apps it can't verify. Clear the quarantine flag once and open it normally:

xattr -cr /Applications/mcping.app

Build from source

Don't want to trust the prebuilt binary? Build your own. You'll need Bun and macOS.

git clone https://github.com/ilbertt/mcping.git
cd mcping
bun install
bun run release

The packaged .app and .dmg land in apps/mcping/release/. An app you build locally isn't quarantined, so it opens without the Gatekeeper prompt above.

How it works

MCP servers can send arbitrary notifications to clients that support receiving them. mcping keeps a connection open to each server you add and turns every notification it receives into a native push notification from your OS.
