High risk — review carefully before installing

This package can run commands on your computer AND reads your secret tokens. That combination means it could potentially steal your credentials. Only install this if you trust the author and understand why it needs these permissions.

What We Found(5 issues)

Each card explains what was found and what it means in plain English. Click "Technical details" for the full breakdown.

HIGHHIGH-003

Caution. This package runs system commands on your computer. This is like giving someone the keys to your terminal. They could run anything — download files, change settings, or access your private data.

Technical details

Direct process execution functions (exec, spawn) can run arbitrary commands. Combined with user input, this enables remote code execution.

HIGHHIGH-005

Caution. This package reads your secret passwords and API tokens from your system. If it also has network access, your credentials could be sent to someone else's server. Check WHY it needs your secrets.

Technical details

Reading sensitive environment variables (tokens, secrets, keys, passwords) suggests data exfiltration. MCP servers should declare required env vars, not silently read secrets.

MEDIUMMED-002

Risky. This package doesn't lock its dependency versions. That means if one of its dependencies gets hacked tomorrow, you'd automatically download the hacked version. Good packages always pin their versions.

Technical details

Using '*' or 'latest' as a dependency version means any future version will be installed automatically — including compromised ones.
