Validate CSV/JSON tables and convert dated amounts to EUR, alongside sourced historical exchange rates, country economic indicators and international public-holiday calendars. Free MCP pilot; no account, API key or wallet required for these tools. Practical tasks: - validate_table: check explicit column types, required values, date/decimal formats, allowed values and duplicate keys. Preserve original rows and explain requested normalization. No row deletion, guessed dates or independent verification of the contents. - convert_currency_batch: convert decimal-string amounts to EUR using exact-date ECB historical references, with explicit rounding, original amounts and source evidence. A missing, stale or mismatched rate blocks the complete export and total; no silent replacement by another date. Try: validate a table of invoice references, amounts and dates; or convert 125.50 USD dated 2025-09-26 to EUR and explain the source rate and rounding. Start with a small batch. Maximum 500 rows and 48,000 UTF-8 argument bytes; tables allow 20 columns and conversions eight currency/year snapshots.
