How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security50

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

What is the VPS Guardian MCP server?
VPS Guardian is an MCP server listed in the public MCP registry as io.github.murzirius/vps-guardian-mcp. Secure SSH bridge for AI agents to observe and safely administer Linux VPSs. This page covers its PyPI package (vps-guardian-mcp).
Is the VPS Guardian MCP server safe to use?
VPS Guardian scores 76 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the VPS Guardian MCP server expose?
VPS Guardian exposes 152 tools: get_system_health, get_top_processes, check_service_status, get_failed_systemd_units, read_service_logs, and 147 more. Their descriptions and schemas cost roughly 8,918 tokens of context every time the server is loaded.
Is the VPS Guardian MCP server still maintained?
VPS Guardian is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the VPS Guardian MCP server under?
VPS Guardian declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
