{"jsonrpc":"2.0","id":1,"method":"tools/list"}mrdata_search_deposits — Search the USGS Mineral Resources Data System for mines, prospects and mineral occurrences by bounding box, site name or commodity. AUTHORITATIVE for "what has been mined near here" and "where are the US lithium/copper/gold occurrences" — returns each site's deposit id, name, development status (Producer, Past Producer, Prospect, Occurrence), coordinates and commodity codes. Sourced from USGS MRData.mrdata_deposit — Full USGS MRDS record for one mineral deposit by its deposit id — commodities with their roles, deposit type and model, development status, operation type, mining method, years of first and last production, discovery method, alternate site names, host rocks, ore and gangue minerals, and the bibliography behind the record. Sourced from USGS MRData.mrdata_commodities — Which commodities are recorded in USGS MRDS inside an area, with a site count per commodity — the "what is this region mined for" tool. Also serves as the lookup for the commodity symbols that mrdata_search_deposits expects. Sourced from USGS MRData.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
