Findings (9)

HIGH
Capability escalation
L132

Detects excessive or dangerous capability requests in MCP configurations

permissions: ["all
FIX

Restrict the tool to well-defined scopes and prevent it from requesting all permissions. Implement least-privilege access controls and audit permission grants.

FP?

Likely FP if the match is a tool description documenting available permission scopes, not a tool that actually requests overly broad access.

MEDIUM
Conditional download and install
L22

Detects patterns that check for tool existence and install if missing

If not installed, install
FIX

Replace conditional download-and-install logic with explicit dependency declarations in a manifest file (package.json, requirements.txt). Verify checksums for any runtime downloads.

FP?

Likely FP if the conditional install is documentation showing standard prerequisite checks (e.g., checking if a tool is installed before installing it).

LOW
pip install arbitrary package
L16

Detects pip install of arbitrary packages that modify the host environment

pip install yt
FIX

Pin all pip packages to exact versions (e.g., pip install package==1.2.3). Use a requirements.txt or pyproject.toml with pinned versions and hash verification.

FP?

Likely FP if the match is in documentation showing how to install the skill's own PyPI package.

LOW
System package manager install
L19

Detects system-level package installation via brew, apt, yum, or dnf

brew install f
FIX

Pin system packages to specific versions where the package manager supports it. Document the exact packages required and prefer containerized environments to avoid system-wide changes.

FP?

Likely FP if the match is standard setup documentation listing well-known system packages (e.g., apt install git curl) that are prerequisites.

LOW
pip install arbitrary package
L24

Detects pip install of arbitrary packages that modify the host environment

pip install yt
FIX

Pin all pip packages to exact versions (e.g., pip install package==1.2.3). Use a requirements.txt or pyproject.toml with pinned versions and hash verification.

FP?

Likely FP if the match is in documentation showing how to install the skill's own PyPI package.

LOW
System package manager install
L25

Detects system-level package installation via brew, apt, yum, or dnf

brew install f
FIX

Pin system packages to specific versions where the package manager supports it. Document the exact packages required and prefer containerized environments to avoid system-wide changes.

FP?

Likely FP if the match is standard setup documentation listing well-known system packages (e.g., apt install git curl) that are prerequisites.

LOW
Mutable GitHub raw content reference
L178

Detects references to raw.githubusercontent.com on mutable branches like main/master

github.com/yt-dlp/yt-dlp/blob/master/supportedsites.md
FIX

Replace GitHub raw.githubusercontent.com references with pinned commit SHAs instead of branch names (e.g., /commit-sha/file instead of /main/file). Branch references are mutable.

FP?

Likely FP if the raw GitHub URL points to a versioned release tag in a well-known repository, though even tags are technically mutable.

LOW
pip install arbitrary package
L193

Detects pip install of arbitrary packages that modify the host environment

pip install yt
FIX

Pin all pip packages to exact versions (e.g., pip install package==1.2.3). Use a requirements.txt or pyproject.toml with pinned versions and hash verification.

FP?

Likely FP if the match is in documentation showing how to install the skill's own PyPI package.

LOW

L198

brew install f
