mcp-sysadmin (kreodevs/mcp-sysadmin) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: we have no way to read this server ourselves. No publisher has claimed this listing.
Provider-agnostic MCP server for managing heterogeneous infrastructure (SSH, Proxmox VE, Virtualizor, Hetzner Cloud, Cloudflare) via a JSON inventory, exposing tools for VM/container management, DNS, firewalls, and SSH operations.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

Install from
M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
Axios Node HTTP adapter can use an inherited proxy after interceptor config cloning
Axios: Excessive recursion in formDataToJSON can cause denial of service
Axios: Nested axios option objects can consume polluted prototype values
Axios: NO_PROXY bypass for 0.0.0.0 local addresses in axios
Axios form serializer maxDepth bypass via {} metatoken
Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
38/38 tools missing one or more hints — list-zones (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list-dns-records (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get-dns-record (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +35 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
Only 16/38 tool handlers declare input schemas (42%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tests exist
No test files found
Add tests that exercise each declared tool.
Shell command execution
2 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
0 critical, 1 high severity in production deps — axios@1.17.0 (high), axios@1.17.0 (medium)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
