Taken individually the reads are specific in a way general search is not: psa_population_report returns the grade breakdown from Auth through PSA 10, search_nyc_violations pulls ECB penalty amounts by BIN, and verify_contractor_license answers from state licensing boards rather than from a directory. The boundaries are worth reading before relying on any of it — verify_contractor_license reaches CA, TX, FL and NY, verify_nurse_license reaches FL and NY, and search_houzz will not search on its own since it consumes a URL you construct. skillguard_verify sits in the same install without sharing its subject, classifying agent skills rather than searching anything.
A search server spanning consumer marketplaces, US licence and compliance registries, and public cost datasets, with a dedicated tool per source.
- Resale search across 13 named marketplaces: marketplace_search covers tcgplayer, reverb, grailed, redfin, bonanza, thriftbooks, abebooks, goodreads, offerup, swappa, stubhub, craigslist and poshmark, narrowed by query, marketplace, location, minPrice, maxPrice, sortBy and limit, returning listings with prices, conditions, seller info and URLs.
- Licence verification against official state boards: verify_contractor_license searches CA, TX, FL and NY by licence number, person name or business name and returns status, expiration, classifications and contact info, and verify_nurse_license searches FL and NY and returns qualifications and enforcement actions.
- Regulatory and municipal records: search_nyc_violations queries NYC Department of Buildings records by address, BIN or block and lot across DOB, Safety and ECB violations with penalty amounts and an aggregate summary mode, while search_fcc and fcc_details return FCC ID certifications with equipment class, grant dates, test reports and compliance documents.
- Cost data with a comparison path built in: childcare_cost reads the DOL National Database of Childcare Prices by ZIP, county or state, childcare_states returns averages across US states, childcare_compare puts up to 10 locations side by side, and home_service_cost returns min, max, average and median pricing for a service in an area.
- Local services and physical inventory: search_thumbtack returns service professionals with ratings, reviews, pricing and hire counts; search_houzz turns a Houzz search URL into pro profiles with projects and contact info; search_estate_sales and estate_sale_details cover EstateSales.net with dates, addresses, items and photos; search_storage and storage_facility_details cover SelfStorage.com with unit sizes, prices, amenities and hours.
- Government surplus auctions end to end: search_gsa_auctions filters GSA lots by query, agency, state, status and bid range, gsa_auction_details returns bid info, inspection dates and sale terms, and gsa_auction_stats aggregates by state, agency, status and total bid amounts.
- Two lookups outside the marketplace theme: psa_population_report returns a graded card's certification details with the full population breakdown from Auth through PSA 10, and search_imdb searches titles or browses the Top 250 Movies, Top 250 TV, Most Popular Movies and Most Popular TV charts.
- skillguard_verify classifies an agent skill or tool as SAFE, CAUTION or DANGER from its permissions, commands and description.
No credentials are configured. search_houzz is the call that needs something prepared beforehand: a Houzz search URL, built by browsing houzz.com/professionals.
