LABSCO SUMMARY
The last step of a task, handled: open the thing.
It does three things and they are the three that let a conversation end in the right window being in front of you. Scope is strictly local macOS — it reads /Applications and asks the OS to open something, nothing more.
What it is
A small MCP server for driving macOS applications: it can tell an agent which apps are installed and start them, including opening a specific file with a specific app.
What you get
- List every application installed in the
/Applicationsfolder - Launch an application by name
- Open a file with a named application
Requirements
macOS and an MCP client. Nothing to build — add npx @joshuarileydev/mac-apps-launcher-mcp-server to your client's config. No account or key. Package version 0.0.1.
Setup effort
One command — npx y @joshuarileydev/mac-apps-launcher-mcp-server
USE CASES
01
Ending a task in the right app
Have the agent open the file it just produced in the application you actually edit it in.
02
Checking what is installed on this Mac
Ask for the application list before deciding which tool to use for a job.
