Quick Start

Quick Start

Auto-discover and scan everything

The fastest way to start — auto-discovers all MCP client configs on your machine and scans them:

aguara scan --auto

Scan a specific directory

aguara scan .claude/skills/

Scan a single file

aguara scan .claude/skills/deploy/SKILL.md

Filter by severity

# Only high and critical
aguara scan . --severity high

# Only critical
aguara scan . --severity critical

CI mode

Shorthand for --fail-on high --no-color — exits with code 1 if high+ findings:

aguara scan .claude/skills/ --ci

Discover MCP clients (no scan)

See which MCP clients are configured on your machine:

aguara discover

JSON output:

aguara discover --format json

Output formats

# Default: colored terminal
aguara scan .

# JSON (for programmatic use)
aguara scan . --format json

# SARIF (for GitHub Code Scanning, VS Code, etc.)
aguara scan . --format sarif -o report.sarif

# Markdown (for PR comments, docs)
aguara scan . --format markdown -o report.md

List available rules

# All rules
aguara list-rules

# Filter by category
aguara list-rules --category prompt-injection
