Tork Guardian

AI governance and safety layer for OpenClaw agents. Protects against unsafe actions, redacts sensitive data, and generates compliance audit trails.

Tork Guardian for OpenClaw

OpenClaw is powerful. Tork makes it safe.

Enterprise-grade security and governance layer for OpenClaw agents. Detect PII, enforce policies, generate compliance receipts, control tool access, and scan skills for vulnerabilities before installation.

Installation

bash

npm install @torknetwork/guardian

Quick Start

typescript

import { TorkGuardian } from '@torknetwork/guardian';

const guardian = new TorkGuardian({
  apiKey: process.env.TORK_API_KEY!,
});

// Govern an LLM request before sending
const result = await guardian.governLLM({
  messages: [
    { role: 'user', content: 'Email [e-mail] about the project' },
  ],
});
// PII is redacted: "Email [EMAIL_REDACTED] about the project"

// Check if a tool call is allowed
const decision = guardian.governTool({
  name: 'shell_execute',
  args: { command: 'rm -rf /' },
});
// { allowed: false, reason: 'Blocked shell command pattern: "rm -rf"' }

Network Security

Tork Guardian governs all network activity — port binds, outbound connections, and DNS lookups — with SSRF prevention, reverse shell detection, and per-skill rate limiting.

Using the network handler

typescript

const guardian = new TorkGuardian({
  apiKey: process.env.TORK_API_KEY!,
  networkPolicy: 'default',
});

const network = guardian.getNetworkHandler();

// Validate a port bind
const bind = network.validatePortBind('my-skill', 3000, 'tcp');
// { allowed: true, reason: 'Port 3000/tcp bound' }

// Validate an outbound connection
const egress = network.validateEgress('my-skill', 'api.openai.com', 443);
// { allowed: true, reason: 'Egress to api.openai.com:443 allowed' }

// Validate a DNS lookup (flags raw IPs)
const dns = network.validateDNS('my-skill', 'api.openai.com');
// { allowed: true, reason: 'DNS lookup for api.openai.com allowed' }

// Get the full activity log for compliance
const log = network.getActivityLog();

// Get a network report with anomaly detection
const report = network.getMonitor().getNetworkReport();

Standalone functions

typescript

import { validatePortBind, validateEgress, validateDNS } from '@torknetwork/guardian';

const config = { apiKey: 'tork_...', networkPolicy: 'strict' as const };

validatePortBind(config, 'my-skill', 3000, 'tcp');
validateEgress(config, 'my-skill', 'api.openai.com', 443);
validateDNS(config, 'my-skill', 'api.openai.com');

Switching policies

typescript

// Default — balanced for dev & production
const guardian = new TorkGuardian({
  apiKey: 'tork_...',
  networkPolicy: 'default',
});

// Strict — enterprise lockdown (443 only, explicit domain allowlist)
const guardian = new TorkGuardian({
  apiKey: 'tork_...',
  networkPolicy: 'strict',
});

// Custom — override any setting
const guardian = new TorkGuardian({
  apiKey: 'tork_...',
  networkPolicy: 'custom',
  allowedOutboundPorts: [443, 8443],
  allowedDomains: ['api.myservice.com'],
  maxConnectionsPerMinute: 30,
});

See docs/NETWORK-SECURITY.md for full details on threat coverage, policy comparison, and compliance receipts.

Example Configs

Pre-built configurations for common environments:

typescript

import {
  MINIMAL_CONFIG,
  DEVELOPMENT_CONFIG,
  PRODUCTION_CONFIG,
  ENTERPRISE_CONFIG,
} from '@torknetwork/guardian';

Config	Policy	Network	Description
MINIMAL_CONFIG	standard	default	Just an API key, all defaults
DEVELOPMENT_CONFIG	minimal	default	Permissive policies, full logging
PRODUCTION_CONFIG	standard	default	Blocked exfil domains (pastebin, ngrok, burp)
ENTERPRISE_CONFIG	strict	strict	Explicit domain allowlist, 20 conn/min, TLS only

typescript

import { TorkGuardian, PRODUCTION_CONFIG } from '@torknetwork/guardian';

const guardian = new TorkGuardian({
  ...PRODUCTION_CONFIG,
  apiKey: process.env.TORK_API_KEY!,
});

Configuration

typescript

const guardian = new TorkGuardian({
  // Required
  apiKey: 'tork_...',

  // Optional
  baseUrl: 'https://www.tork.network',   // API endpoint
  policy: 'standard',                     // 'strict' | 'standard' | 'minimal'
  redactPII: true,                        // Enable PII redaction

  // Shell command governance
  blockShellCommands: [
    'rm -rf', 'mkfs', 'dd if=', 'chmod 777',
    'shutdown', 'reboot',
  ],

  // File access control
  allowedPaths: [],                        // Empty = allow all (except blocked)
  blockedPaths: [
    '.env', '.env.local', '~/.ssh',
    '~/.aws', 'credentials.json',
  ],

  // Network governance
  networkPolicy: 'default',               // 'default' | 'strict' | 'custom'
  allowedInboundPorts: [3000, 8080],       // Ports skills may bind to
  allowedOutboundPorts: [443],             // Ports for outbound connections
  allowedDomains: ['api.openai.com'],      // If non-empty, only these domains are allowed
  blockedDomains: ['evil.com'],            // Domains always blocked
  maxConnectionsPerMinute: 60,             // Per-skill egress rate limit
});

Policies

Policy	PII	Shell	Files	Network
strict	Deny on detection	Block all	Whitelist only	Block all
standard	Redact	Block dangerous	Block sensitive	Allow
minimal	Redact	Allow all	Allow all	Allow all

Standalone Functions

typescript

import { redactPII, generateReceipt, governToolCall } from '@torknetwork/guardian';

// Redact PII from text
const result = await redactPII('tork_...', 'Call 555-123-4567');

// Generate a compliance receipt
const receipt = await generateReceipt('tork_...', 'Processed user data');

// Check a tool call against policy
const decision = governToolCall(
  { name: 'file_write', args: { path: '.env' } },
  { policy: 'standard', blockedPaths: ['.env'] }
);

Security Scanner

Scan any OpenClaw skill for vulnerabilities before installing it. The scanner checks for 14 security patterns across code and network categories.

CLI

bash

# Scan a skill directory
npx tork-scan ./my-skill

# Full details for every finding
npx tork-scan ./my-skill --verbose

# JSON output for CI/CD
npx tork-scan ./my-skill --json

# Fail on any high or critical finding
npx tork-scan ./my-skill --strict

Programmatic

typescript

import { SkillScanner, generateBadge } from '@torknetwork/guardian';

const scanner = new SkillScanner();
const report = await scanner.scanSkill('./my-skill');

console.log(`Risk: ${report.riskScore}/100`);
console.log(`Verdict: ${report.verdict}`); // 'verified' | 'reviewed' | 'flagged'

See docs/SCANNER.md for the full rule reference, severity weights, and example output.

Tork Verified Badges

Skills that pass the security scanner receive a Tork Verified badge:

Badge	Score	Meaning
Tork Verified (green)	0 - 29	Safe to install
Tork Reviewed (yellow)	30 - 49	Manual review recommended
Tork Flagged (red)	50 - 100	Security risks detected

typescript

import { SkillScanner, generateBadge, generateBadgeMarkdown } from '@torknetwork/guardian';

const scanner = new SkillScanner();
const report = await scanner.scanSkill('./my-skill');
const badge = generateBadge(report);

// Add to your README
console.log(generateBadgeMarkdown(badge));
