## 8 Production Tools Included

### Cluster A: B2B Lead Generation, Email Verification & Website Intelligence
| MCP Tool Name | Apify Engine | Key Capabilities |
|---|---|---|
| `find_and_verify_corporate_emails` | [`invaluable_rondeau/corporate-email-finder-verifier`](https://apify.com/invaluable_rondeau/corporate-email-finder-verifier) | Resolve & verify corporate emails from `{fullName, domain}` (up to 500 leads/run) with honorific stripping and **MX Provider Fingerprinting** (`google_workspace`, `microsoft_365`, `proofpoint`, `mimecast`, `cloudflare`). |
| `enrich_company_websites` | [`invaluable_rondeau/b2b-website-enricher`](https://apify.com/invaluable_rondeau/b2b-website-enricher) | Extract `companyName`, `metaDescription`, 20+ B2B `techStack` signatures (Stripe, HubSpot, Salesforce, Marketo, Segment, Next.js, Intercom), role-based `publicEmails`, `socialLinks`, and `sizeSignals`. |
| `score_email_deliverability_risk` | [`invaluable_rondeau/b2b-email-deliverability-risk-gate`](https://apify.com/invaluable_rondeau/b2b-email-deliverability-risk-gate) | Score B2B email lists (`0–100`) for bounce, disposable, role-account, and spam-trap risk; route each address into `send` / `review` / `suppress`. |

### Cluster B: Domain, Email Security (SPF/DMARC/DKIM), SSL/TLS & RDAP Drift Monitoring
| MCP Tool Name | Apify Engine | Key Capabilities |
|---|---|---|
| `audit_domain_email_security` | [`invaluable_rondeau/b2b-domain-email-security-auditor`](https://apify.com/invaluable_rondeau/b2b-domain-email-security-auditor) | Audit domain SPF, DMARC (`p=none/quarantine/reject`), DKIM selectors, BIMI, MTA-STS, TLS-RPT, and spoofing risk (`0–100`) with stateful drift tracking. |
| `monitor_ssl_tls_certificates` | [`invaluable_rondeau/ssl-tls-certificate-drift-monitor`](https://apify.com/invaluable_rondeau/ssl-tls-certificate-drift-monitor) | Inspect live TLS handshakes, certificate expiry countdown (`daysRemaining`), CA issuer, Subject Alternative Names (`SANs`), and SHA-256 fingerprint changes. |
| `monitor_domain_rdap_expiry` | [`invaluable_rondeau/domain-rdap-expiry-registrar-monitor`](https://apify.com/invaluable_rondeau/domain-rdap-expiry-registrar-monitor) | Query authoritative IANA RDAP registries directly (no WHOIS rate-limit blocks) for domain age (`domainAgeYears`), expiration countdown (`daysUntilExpiry`), registrar, DNSSEC, and EPP transfer-lock status. |

### Cluster C: Quantitative Trading, MT5 / TradingView Overfitting Audit & Portfolio Kelly Sizing
| MCP Tool Name | Apify Engine | Key Capabilities |
|---|---|---|
| `audit_trading_strategy_overfitting` | [`invaluable_rondeau/trading-strategy-overfitting-stress-auditor`](https://apify.com/invaluable_rondeau/trading-strategy-overfitting-stress-auditor) | Audit **MT5, MT4, TradingView & quant backtests** across **7 institutional deployment gates**: Walk-Forward Efficiency (`WFE`), top-3 outlier reliance, **1,000-run Monte Carlo execution slippage & spread-spike stress**, **Prop Firm (FTMO / FundedNext) pass probability simulator**, and **MQL5 live-safety static code linter**. |
| `optimize_multi_strategy_portfolio` | [`invaluable_rondeau/multi-strategy-portfolio-correlation-kelly-optimizer`](https://apify.com/invaluable_rondeau/multi-strategy-portfolio-correlation-kelly-optimizer) | Construct orthogonal multi-EA portfolios: compute pairwise daily PnL correlation (`r`) and **Tail Co-Crash Ratio**, split **Tier-1 Live** vs **Tier-2 Bench Reserve** rosters, and calculate **Risk-Parity & Half-Kelly lot allocations** under your `targetMaxDrawdownPct` cap. |
