}Coverage and interpretation
Use the focused guides for their exact coverage. Other general tools include ten NWS US forecast points, a rolling USGS M2.5+ earthquake feed and the latest 20 French RappelConso notices; none is exhaustive.
Read status, returned, observation dates, units, nulls, freshness, citation and provenance. Collection time is not the observation period. Historical values can be revised. independently_verified remains false: official-source and schema checks are not independent factual corroboration. Missing information stays unavailable.
Troubleshooting and verification
Use Streamable HTTP with the exact endpoint above. Client policies and workspace trust may restrict MCP. No authentication is required for factual tools. A successful HTTP status alone does not prove usable data: inspect the structured status. An out-of-theme tool requires another scope.
Runnable HTTP and SDK examples · Dated response excerpts · Live catalog · OpenAPI · Plain-text quickstart
Configuration syntax checked against official client documentation; SDK tests are not end-to-end certification of each client interface. No uptime guarantee during the pilot. The optional paid HTTP country report is separate and is never called by these examples.
