Contractor License + Bond + Insurance Verify (MCP, agent-payable)

The only MCP-native license check that returns official SURETY BOND + INSURANCE from state data — not just active/inactive status. Pay-per-success: $0.03 full result, $0.01 status-only, FREE on a miss. WA live (official L&I), CA beta (CSLB).

Tools: verify_license, list_supported_jurisdictions.

Quickstart

// Call
{ "tool": "verify_license", "jurisdiction": "WA", "license_number": "ECOSTSC758NN" }

// Response (abridged)

    "insured": { "has_insurance": true, "details": "Carrier: State National Ins Co Inc; Coverage: $1,000,000" }
  }
}

Result	Price
Full (status + bond + insurance)	$0.03
Status-only (no bond/insurance match, or `statusOnly: true`)	$0.01
Miss (`found: false`)	FREE

Jurisdictions

State	Status	Source	Bond + Insurance
WA	✅ Live	WA L&I open data (data.wa.gov)	✅ Real data (bzff-4fmt + ciwg-agsx datasets)
CA	⚠️ Beta	CSLB HTML (cslb.ca.gov)	✅ Parsed when CSLB is up

Washington is the reliable, production-ready jurisdiction. Official WA L&I open data is served via Socrata JSON — no scraping, no rate limits, bond and insurance data included from dedicated datasets.

California is beta. CSLB does not publish an open API; the provider fetches the HTML detail page directly. CSLB rate-limits or 503s automated requests intermittently. When unavailable, verify_license returns a clean SESSION_ERROR — you are never charged on source failures. Do not rely on CA for production workflows until a stable server-side CSLB run is confirmed.
