Which integrations are available for this server?

Allows exporting compliance logs in JSONL format for ingestion into Elastic for logging and analytics. Allows forwarding of compliance logs in CEF format to Splunk for SIEM monitoring and analysis.

How do I use Chrome MCP Server (Security Hardened)?

1. Click on "Deploy Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Chrome MCP Server (Security Hardened) access the corporate portal and take a screenshot of the dashboard" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

Compliance Logging

SIEM-ready logging in industry-standard formats. Every tool execution, credential access, and security event is logged.

Output Formats

Format	Use Case	Example
CEF	Splunk, ArcSight, QRadar	`CEF:0\|Pantheon-Security\|Chrome-MCP-Secure\|2.3.0\|...`
Syslog	Centralized logging (RFC 5424)	`<134>1 2025-12-16T10:30:00Z ...`
JSONL	Elastic, custom pipelines	`{"timestamp":"...","category":"audit",...}`

Event Categories (OWASP-Compliant)

authentication - Login attempts, session creation
authorization - Access control decisions
credential - Vault operations (store, retrieve, delete)
audit - Tool executions with timing
security - Rate limits, injection attempts, anomalies
data_access - Sensitive data retrieval

Quick Configuration

# Enable CEF logging for Splunk
COMPLIANCE_LOG_FORMAT=cef
COMPLIANCE_LOG_DIR=./logs/compliance

# Forward to remote syslog
SYSLOG_HOST=siem.company.com
SYSLOG_PORT=514

Example CEF Output

CEF:0|Pantheon-Security|Chrome-MCP-Secure|2.3.0|audit:tool:navigate|tool:navigate|3|rt=1702732800000 outcome=success msg=Tool navigate executed: success request=https://internal.company.com cn1=1702732800-abc123 cn1Label=correlationId

Real-World Results

"We used this MCP for hours building out our security dashboard - the reliability was incredible. The amount of work we produced was huge compared to manual browser interaction." — Pantheon Security team

Production Tested

Metric	Result
Session Duration	4+ hours continuous use
Stability	Zero crashes or disconnects
Credential Security	All logins encrypted, auto-wiped
Productivity Gain	10x faster than manual browser work

This isn't just a security enhancement - it's a reliable workhorse for AI-assisted browser automation. When you need Claude to interact with web apps for extended sessions, this MCP delivers.

Security Features

Core Security (v2.1.0)

Feature	Description
Post-Quantum Encryption	ML-KEM-768 + ChaCha20-Poly1305 hybrid
Secure Credential Vault	Encrypted at rest, auto-wiped from memory
Memory Scrubbing	Zeros sensitive data after use
Audit Logging	Tamper-evident logs with hash chains
Profile Isolation	Dedicated Chrome profile for secure sessions
Log Sanitization	Credentials masked in all output
Rate Limiting	100 requests per minute per operation
Input Validation	CSS selector sanitization, URL validation

Advanced Security Modules (v2.2.0+)

Module	Description
Secrets Scanner	Detects 25+ credential patterns (AWS, GitHub, Slack, OpenAI keys, private keys, JWTs, credit cards, SSNs)
Response Validator	Prompt injection detection (15 patterns), suspicious URL blocking, encoded payload detection
Session Manager	Credential session lifecycle with 8h max lifetime and 30min inactivity timeout
MCP Authentication	Token-based auth with auto-generation, SHA256 hashing, brute-force lockout
Certificate Pinning	SPKI-style pinning for Google, GitHub, Microsoft, Anthropic, OpenAI domains
Screenshot Redaction	Auto-redacts password fields, credit cards, CVV, SSN, API keys in screenshots
Cross-Platform Permissions	Secure file permissions on Linux, macOS, and Windows (icacls)

Post-Quantum Ready

Traditional encryption will be broken by quantum computers. This fork uses hybrid encryption:

ML-KEM-768 (Kyber) + ChaCha20-Poly1305

ML-KEM-768: NIST-standardized post-quantum key encapsulation
ChaCha20-Poly1305: Modern stream cipher (immune to timing attacks)

Even if one algorithm is broken, the other remains secure.

Why Post-Quantum Now?

Timeline	Threat
2024-2030	"Harvest now, decrypt later" attacks - adversaries collecting encrypted data today
2030-2035	Early cryptographically-relevant quantum computers expected
2035+	Current RSA/ECC encryption potentially broken

Your browser credentials stored today could be decrypted in 10 years. This fork protects against that future threat now.

Memory Protection

SecureCredential class: Auto-wipes credentials after TTL (5 min default)
Zero-fill buffers: Random overwrite + zero fill prevents memory dumps
No credential logging: Automatic masking of sensitive field names

Why ChaCha20-Poly1305 over AES-GCM?

Property	ChaCha20-Poly1305	AES-GCM
Timing attacks	Immune (constant-time)	Vulnerable without AES-NI
Software speed	Fast everywhere	Slow without hardware
Complexity	Simple	Complex (GCM mode)
Adoption	Google, Cloudflare TLS	Legacy systems

What's New in v2.2.x

v2.2.1 - Cross-Platform File Permissions

All file operations use centralized file-permissions.ts
Proper Windows ACL support via icacls
Consistent 0o700/0o600 permissions on Unix

v2.2.0 - Advanced Security Modules

Six new security modules totaling 3,000+ lines of security hardening:

Secrets Scanner - Detects leaked credentials in page content using patterns from TruffleHog, GitLeaks, and MEDUSA
Response Validator - Blocks prompt injection attacks in scraped content
Session Manager - Auto-expires credential sessions after configurable timeouts
MCP Authentication - Protects the MCP server itself with token-based auth
Certificate Pinning - Validates TLS certificates for sensitive domains
Screenshot Redaction - Overlays sensitive fields before screenshots

See CHANGELOG.md for full version history.

Troubleshooting

Chrome not accessible

curl http://localhost:9222/json
# If no response, start Chrome:
./setup.sh --start-chrome

Credential decryption fails

Check if you changed machines (machine-derived key won't work)
Set CHROME_MCP_ENCRYPTION_KEY to the same key used to encrypt
Credentials may need to be re-stored if key is lost

Element not found

Use get_page_info to see available elements
Use wait_for_element for dynamic content
