How do I install Ultranix?

Copy the stdio config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

Does Ultranix need an API key?

The publisher lists these environment variables: 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.

What transport does Ultranix use?

Ultranix runs locally over stdio.

Credentials from the publisher

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)

Claude Code has no install link for a local command. Copy the command below and run it in a terminal.
