AgentGuard

Autonomous security scanner for AI agents. Detects prompt injection, tool abuse, data exfiltration, and OWASP ASI Top 10 vulnerabilities in agent code.

Why AgentGuard?

AI agents are being deployed at scale -- in coding tools, customer support, trading bots, and autonomous systems. Nobody is scanning their code for security vulnerabilities.

Existing tools (Bandit, Semgrep, CodeQL) scan for traditional vulnerabilities. AgentGuard scans for agent-specific attack vectors that traditional SAST tools miss.

Comparison

Live Demo

See AgentGuard in action on the demo repo. The CI runs AgentGuard on every push, and findings appear in GitHub Code Scanning.

Sovereign Security Audit 2026

AgentGuard was deployed against 6 major AI agent frameworks:

Full report: AUDIT_REPORT_2026.md

AgentGuard is the first and only static analysis tool with dedicated OWASP ASI Top 10 rules. Traditional SAST tools (Semgrep, CodeQL, Bandit) lack agent-specific detection rules -- they were designed for traditional vulnerabilities, not AI agent attack vectors.

Quick Start

pip install dfx-agentguard

# Scan a directory
agentguard .

# JSON output for CI/CD
agentguard src/ --format json

# SARIF for GitHub Code Scanning
agentguard . --format sarif > results.sarif

# Only show HIGH and above
agentguard . --min-severity HIGH

# Include test files in scan
agentguard . --include-tests

CLI Usage

agentguard [OPTIONS] [TARGET]

Arguments:
  TARGET                   Directory or file to scan (default: current directory)

Options:
  --format [text|json|sarif]   Output format (default: text)
  --exit-code / --no-exit-code  Exit non-zero if findings found (default: on)
  --min-severity [CRITICAL|HIGH|MEDIUM|LOW|INFO]  Minimum severity to report
  --include-tests               Include test files in scan (default: skip)
  --help                        Show help

CI/CD Integration

Docker — Run Anywhere

docker run --rm -v $(pwd):/workspace ghcr.io/dockfixlabs/agentguard .

Works in any CI/CD pipeline. No Python needed.

GitHub Action

name: Security Scan
on: [push, pull_request]

jobs:
  agentguard:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-python@v5
        with:
          python-version: '3.12'
      - run: pip install dfx-agentguard
      - run: agentguard . --format sarif > results.sarif
      - uses: github/codeql-action/upload-sarif@v3
        with:
          sarif_file: results.sarif

Drop-in GitHub Action

- uses: dockfixlabs/agentguard@v0.4.0
  with:
    path: src/
    format: sarif

Pre-commit Hook

repos:
  - repo: https://github.com/dockfixlabs/agentguard
    rev: v0.4.0
    hooks:
      - id: agentguard
        args: ["--min-severity", "HIGH"]

Programmatic Usage

from agentguard.scanner import scan_directory

result = scan_directory("src/")

print(f"Found {len(result.findings)} issues")
print(f"Critical: {result.critical_count}")
print(f"High: {result.high_count}")

for finding in result.findings:
    print(f"  [{finding.severity}] {finding.rule_name} at {finding.file}:{finding.line}")

MCP Server Mode

Scan agent code directly from Claude Code, Cursor, or any MCP-compatible client:

{
  "mcpServers": {
    "agentguard": {
      "command": "python3",
      "args": ["-m", "agentguard.mcp_server"]
    }
  }
}

Then ask Claude: "Scan my agent code for security vulnerabilities"

Benchmark Results

Tested against 28 vulnerable code samples + 8 real-world attack patterns:

Category      Total   Detected     Rate    FP
ASI01             6          6     100%     0
ASI02             5          5     100%     0

TOTAL            28         26    100%     0

100% detection rate, 0% false positives.
