Nothing to run from here
Ultranix is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

# deploy-notes
Ultranix costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. This one runs on your machine: your client starts Ultranix as a process under your own user, with your files and your network, so the tool surface below is what it can do to your computer rather than to a server somewhere else. It has not been scanned here, so read the surface, and its source, before you approve it.
Claude Codedeclared by this listing
This is a public server: you run it yourself and this marketplace is not in the path. You need Docker installed and running. Only the required variables are passed into the container. To set an optional one (ULTRANIX_MCP_API_KEY, ULTRANIX_MCP_API_KEY_FILE, ULTRANIX_MCP_API_KEY_EXPIRES, ULTRANIX_MCP_HISTORY_SECRET, ULTRANIX_MCP_SENTRY_DSN, ULTRANIX_MCP_AUDIT_SECRET), add -e NAME before the image name and give it a value in the entry’s env: an unset -e would clear the default the image sets. Claude Code registers it in one command; --scope user makes it available in every project. The '--' is in quotes so that PowerShell passes it on.
claude mcp add --scope user ultranix-mcp '--' docker run -i --rm --platform linux/amd64 ghcr.io/jxoesneon/ultranix-mcp:1.4.0Reconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it runs from its publisher’s own image: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it asks of you
Nothing is required, but it can take ULTRANIX_MCP_API_KEY (API key(s) (uxcp_*) for HTTP transport auth - required for --transport http (fail-closed), unused on stdio), ULTRANIX_MCP_API_KEY_FILE (Path to a 0600 file holding uxcp_* keys, one per line), ULTRANIX_MCP_API_KEY_EXPIRES (Optional RFC 3339 expiry for the env-sourced key (self-revoking)), ULTRANIX_MCP_HISTORY_SECRET (AES-256-GCM secret for encrypted action history (per-install generated if unset)), ULTRANIX_MCP_SENTRY_DSN (Optional Sentry DSN for error reporting (unset = disabled)), ULTRANIX_MCP_AUDIT_SECRET (Optional HMAC-SHA256 signing secret for audit.jsonl lines (tamper evidence for SIEM ingestion)) if you want to set them.
What it writes
One config entry your client uses to start the process locally. A local server runs with your file system and your network, which is why it is priced without metering.
What you approve
1 tool, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

—Grade not published
No rule-by-rule report on file for this release
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing ships as a container image. The scanner reads packages on npm and PyPI and public source; an image is neither, so there is no grade here — not a withheld one, an unmeasured one.
Release history
It installs from a container image rather than from a versioned package, so the command cannot be pinned to a release. The history below is for reading; the current release on file is 1.4.0.

Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish Ultranix can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
