Contractor License Verification (TradesAPI)
This server connects Claude to live contractor licensing databases across all 50 US states, DC, and 8 major city portals including Chicago, NYC, and Las Vegas. You get three tools: verify_license hits the official state board with a license number and returns status, expiration, and disciplinary history; batch_verify handles up to 25 lookups in parallel; search_by_name does fuzzy matching when the jurisdiction supports it. Results are cached for 24 hours but you can force refresh. It's backed by TradesAPI and works via streamable-http or stdio. Each verification costs one credit, new accounts get 50 free. Reach for this when you're building compliance checks, vetting subcontractors, or need to answer licensing questions without opening 50 browser tabs.
