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(11 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.

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-004

Suspicious. This package loads code from an unknown location decided at runtime. We can't tell what it will actually run because it depends on a variable. This makes it harder to verify the package is safe.

Technical details

Dynamic require/import with variable arguments loads code determined at runtime. This can be used to load payloads that static analysis can't detect.
