Remote MCP endpoint:

https://datoqa.bhazarstudio.workers.dev/mcp/fx

Connect one scope. Adding both the general server and every theme duplicates tools. Review and merge configuration with existing servers; do not overwrite another connection named datoqa.

Coverage and interpretation

ECB reference rates quote currency units per one EUR. Historical coverage starts in 1999 and varies by currency and year. Rates are indicative, not live or executable. No weekend carry-forward or invented rate.

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.

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.
