earthquake-mcp-server

Use the earthquake_* tools to query seismic data from USGS ComCat and the EMSC SeismicPortal; no API key required. earthquake_get_feed gives USGS real-time magnitude tiers for current activity; earthquake_search handles historical or filtered queries, sized first with earthquake_count (search caps at 20,000 events). Both emit network-specific event IDs (e.g. us6000sznj) for earthquake_get_event, which returns full USGS detail (EMSC has no per-event endpoint). USGS carries richer metadata (PAGER, DYFI, ShakeMap); source=emsc is an independent global catalog from the European-Mediterranean Seismological Centre, useful for cross-checking an event of any region against a separate network, and does not apply USGS-only filters (the response names them in ignoredFilters).
