agentsec-ai 0.4.5

Security scanner for AI agents and MCP servers. OWASP Agentic Top 10 mapping, SARIF output, CI/CD ready.

agentsec

Static configuration scanner and hardener for AI agent installations. Detects misconfigurations, credential leaks, supply-chain risks, and MCP tool poisoning — then maps every finding to the OWASP Top 10 for Agentic Applications (2026).

Supports OpenClaw, Claude Code, Cursor, Windsurf, Gemini CLI, and MCP server ecosystems.

Scope: agentsec performs static configuration and file analysis. It does not provide runtime protection, behavioral monitoring, or real-time threat detection. Use as one layer in a defense-in-depth strategy.

Quick Start

pip install agentsec-ai
agentsec scan

Scan a specific installation:

agentsec scan ~/.openclaw

What agentsec checks

Module	Scope
installation	Gateway exposure, auth posture, DM/group policy, tool/sandbox settings, SSRF and safety checks, known CVE version checks, sensitive file/dir permissions
skill	Instruction malware, risky code patterns (eval/exec/subprocess), prompt-injection patterns, frontmatter capability risk, dependency/install-hook risk
mcp	Tool poisoning patterns, auth gaps on remote endpoints, dangerous schema/permissions, unverified npx usage
credential	detect-secrets engine (23 plugins) + 11 custom patterns (OpenAI, Anthropic, AWS, Databricks, HuggingFace, etc.), high-entropy detection, git credential leakage

Reference catalog:

• Checks Catalog (27 named checks + dynamic credential findings)
• CLI Reference (full command/options guide)

Core Commands

# Full installation scan (all scanners, default target=. )
agentsec scan

# JSON report for CI parsing and pipelines
agentsec scan -o json -f report.json

# SARIF output for GitHub code scanning upload
agentsec scan -o sarif -f results.sarif

# Run only selected scanners for focused checks
agentsec scan -s installation,mcp

# Fail build only at/above selected severity
agentsec scan --fail-on critical

# Preview profile changes without writing config
agentsec harden -p workstation

# Apply profile and write hardened config values
agentsec harden -p workstation --apply

# Watch files and auto re-scan on security-relevant changes
agentsec watch ~/.openclaw -i 2

# Pre-install package gate (scan before install)
agentsec gate npm install express

# Pin MCP tool descriptions for rug-pull detection
agentsec pin-tools

# Generate shell hook wrappers for npm/pip install flows
agentsec hook --shell zsh

Hardening Profiles

Profile	Intended use
workstation	Single-owner local usage
vps	Remote/self-hosted deployment
public-bot	Highest restriction for untrusted public input

Use agentsec show-profile <name> to inspect exact changes before applying.

Output and Exit Codes

Output formats:

• terminal (default)
• json
• sarif

Exit codes:

• 0: no findings at/above threshold
• 1: findings found at/above threshold
• 2: usage error (e.g., unknown scanner name)
• 3: runtime error (e.g., file access failure)

Screenshots

Screenshots below show the experimental demo sandbox flow (intentionally insecure configuration for detection and hardening demonstration). Gate and hook behavior are documented in docs/case-studies/003-preinstall-gate-blocked-malicious-package.md and docs/adr/ADR-0004-pre-install-gate.md.

Step 1: Initial scan on intentionally insecure demo config

Step 2: Apply workstation hardening profile

Step 3: Re-scan findings after hardening

Step 4: OWASP posture view after hardening

Benchmarks and Studies

• Fixture benchmark — precision/recall/F1 over a 20-fixture suite (self-authored fixtures, not independently validated).
• Top-50 MCP study — agentsec-only repro run with normalized findings output.
• Top-50 study kit — schema, selection CSV, JSONL findings, and summary JSON.

Current checked-in Top-50 summary data:

• docs/benchmarks/top50/reports/top50_summary_20260215.json
• docs/benchmarks/top50/reports/top50_findings_20260215.jsonl

Reproducibility

Fixture benchmark:

python docs/benchmarks/run_benchmark.py

Top-50 study repro:

powershell -ExecutionPolicy Bypass -File scripts\reproduce_top50_study.ps1 -DateStamp 20260215

Note: semgrep and gitleaks baseline runs are optional in the PowerShell repro script and require those tools on PATH.

Adversarial consistency audit (docs vs artifacts):
