Nothing serious here today

Today is the operative word: we check XHelio-SPICE every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Claude Code Claude Desktop Codex Cursor VS Code

run in your terminal

claude mcp add xhelio-spice -- uvx xhelio-spice

~/Library/Application Support/Claude/claude_desktop_config.json

command = "uvx"
args = ["xhelio-spice"]

This one needs environment variables set before it will start: XHELIO_SPICE_KERNEL_DIR (Override the default kernel cache directory (~/.xhelio_spice/kernels/)). The author declared them in the registry entry; get the values from the project itself.

XHelio-SPICE — questions

Answers built from our own checks of this server.

Why is there no uptime for XHelio-SPICE?

XHelio-SPICE runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package xhelio-spice was installed 33 times last week.

How do I connect XHelio-SPICE?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls xhelio-spice straight from pypi; nothing to host, nothing to sign up for.

How many people use XHelio-SPICE?

The pypi package xhelio-spice was installed 33 times in the last week. Week over week that is -48%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is XHelio-SPICE open source?

Yes — it is published under the MIT licence, written in Python and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
