Security profile

Exposure: Minimal

Stays within its own process: at most external requests and local configuration.

What this server can reach, from a static read of the shipped code. Nothing was executed and nothing here is a verdict: a browser tool has to run commands and an API wrapper has to call its API. Decide what fits your setup.

NVIDIA SkillSpector v2.11.0, MCPVault MCP-server policy. Scanned 6 days ago @ a9fdecb.

Detected

Nothing in the shipped code matched a capability pattern.

Not detected: reads environment variables in bulk, sends conversation content outward, runs shell commands, reads or writes other agents' configuration, accesses credential files, uses elevated privileges, installs itself to run later, matches a known malicious pattern.

Dependencies with known advisories

None found in the lockfiles and manifests checked against OSV.dev.

Left out of the profile

2 pattern matches in documentation, configuration or CI files were recorded but are not part of the profile, because they do not run when the server does. The owner dashboard lists them.

How the profile works Maintainers see file, line and a fix for each item in their dashboard.
