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
| set -g default-terminal 'tmux-256color' | |
| # Enable 24 bit true colors | |
| set -ga terminal-overrides ',*:Tc' |
| ctrl_table = { | |
| sends_escape = true, | |
| last_mods = {} | |
| } | |
| control_key_timer = hs.timer.delayed.new(0.15, function() | |
| ctrl_table["send_escape"] = false | |
| -- log.i("timer fired") | |
| -- control_key_timer:stop() | |
| end |
Most client-side applications need to fetch data over the network. In the Ember.js ecosystem, many developers use a high-level abstraction, like Ember Data, that standardizes network access via an adapter pattern.
For those who want more low-level control over data fetching, it is
