Security profile

Exposure: Limited

Runs commands or loads code on your machine, but does not reach secrets or other agents.

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 yesterday @ bf7dc50.

Detected

Installs itself to run later7 places
Writes startup entries, cron jobs or state files that outlive the session.
Runs unpinned packages at runtime2 places
Executes npx or uvx without a version, so a compromised upstream release would run.

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, matches a known malicious pattern.
