License Verify MCP Server

license-verify-mcp

Verify contractor license status mid-task. Returns normalized JSON with active|expired|suspended|revoked status, bond details, and insurance. Two delivery modes: MCP server (stdio, for Claude/agent use) and Apify Actor (pay-per-event, agentic-payments eligible).

---

Jurisdictions

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.

---

Apify Actor

Agentic-payments eligible — pay-per-event pricing + limited permissions + no Standby mode.

Pricing

Charged only on found: true. Validation errors, not-found results, and source failures are not charged.

Input

{
  "jurisdiction": "WA",
  "license_number": "ECOSTSC758NN"
}

Output (default dataset)

{
  "found": true,
  "jurisdiction": "WA",
  "query": { "license_number": "ECOSTSC758NN" },
  "result": {
    "license_number": "ECOSTSC758NN",
    "business_name": "!ECO STAR C G CONSTRUCTION LLC",
    "status": "active",
    "license_type": "CONSTRUCTION CONTRACTOR",
    "bonded": {
      "is_bonded": true,
      "details": "Surety: NORTH RIVER INSURANCE COMPANY THE; Bond #: 46CF842686; Amount: $30,000; Effective: 2025-08-05; Expires: Until Canceled"
    },
    "insured": {
      "has_insurance": true,
      "details": "Carrier: State National Ins Co Inc; Policy: NXT9PTHTLT-01-GL; Coverage: $1,000,000; Agency: Next Insurance Inc; Effective: 2026-06-12; Expires: 2027-06-12"
    },
    "effective_date": "2025-08-15",
    "expiration_date": "2027-08-15"
  },
  "source_url": "https://data.wa.gov/resource/m8qx-ubtq",
  "retrieved_at": "2026-06-26T01:34:37.598Z",
  "raw": { ... }
}

status is always one of: active | expired | suspended | revoked | unknown.

On failure: { "found": false, "error": "SESSION_ERROR|NETWORK_ERROR|...", "message": "..." } — never a crash, never a charge.

Local test

npm install
npm run build
echo '{"jurisdiction":"WA","license_number":"ECOSTSC758NN"}' \
  > storage/key_value_stores/default/INPUT.json
npx apify run

2. Register it in src/providers/index.ts

No other changes needed in server or Actor.
