If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

The package's postinstall lifecycle script runs automatically on `npm install` and collects installer host identifiers (hostname, platform, arch, node version, package name, timestamp) and POSTs them to the hardcoded endpoint https://6cjhdzmo.instances.poc.jchunt.top/xrblocks-mcp. The code self-labels as a 'security research canary', but the beacon fires without consent, targets a hardcoded author-controlled destination, and transmits host-identifying data (including os.hostname()) that has no bearing on the package's declared functionality.
