Troubleshooting MCP Server Launch Failures on M1 Mac (Claude Desktop Integration)

Context and Symptoms

When attempting to integrate a local MCP (Model Context Protocol) server with Anthropic’s Claude Desktop app on an M1 MacBook, users have encountered launch failures. In this scenario, the MCP server (written in Python 3.10–3.13 and run in a virtual environment) fails to start when Claude Desktop tries to connect to it. The Claude app’s logs repeatedly show an error message like:

Error: spawn uv ENOENT

Time command on OSX, Linux

The time command on OSX has less features than gnu-time gtime on Linux.

You can install gtime on OSX with Homebrew: brew install gnu-time

Example:

> time sleep 2

real	0m2.009s

Very simple, fragile, multi-line text parsing in javascript
// Let's parse the lines in from our textarea
var textarea = $("#mytextarea").val();
// Different browsers represent end of lines differently, so make all end of lines \n */
lines = textarea.replace(/\r\n/g, "\n").split("\n");
