Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (10)

`check_email_domain`	Check whether a domain can actually receive email (has MX records) via a real DNS-over-HTTPS lookup — validate a customer/supplier email's domain before sending or invoicing. An LLM can't know current DNS; this does the live lookup.
`payout_reconciliation`	Explain why a payout is less than sales: walk gross -> deductions -> expected, and (if actual_deposit given) flag the unexplained gap (shortfall/surplus).
`reorder_point`	Reorder point = lead-time demand + safety stock. If on_hand is given, returns whether to reorder now and the days of cover remaining.
`stripe_connect_split`	Compute the Stripe Connect three-way split for one charge. Returns what the buyer pays, what Stripe takes, what the platform nets (its application fee), and what the connected seller nets — plus the platform's effective take rate. fee_bearer: 'seller' \| 'platform' \| 'buyer' (who absorbs the Stripe processing fee). Rates are editable; defaults are US card standard 2.9%+$0.30.
`validate_aba_routing`	Validate a US ABA bank routing number (9 digits) by its checksum. Catch typos before initiating an ACH/wire payout. Pure-algorithm; nothing leaves the machine.
`validate_eori`	Validate an EORI number (Economic Operators Registration and Identification) against the official EU customs database (live lookup). An EORI is required for EU imports/exports — check a trading partner's or your own EORI before customs filings / freight bookings. Input e.g. 'DE1234567890123' (country code + number).
`validate_eu_vat`	Validate an EU VAT number against the official EU VIES service (live government lookup). Returns whether it is registered/valid and, if available, the registered trader name + address. An LLM cannot know this without the real lookup — use this before invoicing/reverse-charging an EU B2B customer. Input e.g. 'DE811569869' or 'IE6388047V' (country code + number).
`validate_gtin`	Validate a GTIN / UPC / EAN barcode (GTIN-8/12/13/14) by its check digit. Catches mistyped product barcodes in inventory/catalog workflows. Pure-algorithm.
`validate_iban`	Validate an IBAN (International Bank Account Number) by structure + the ISO 7064 mod-97 checksum. Catches typos/invalid accounts before you initiate a transfer. Pure-algorithm; no data leaves the machine.
`vat_rate_by_country`	EU VAT rates (standard / reduced / super-reduced / parking) for a country, from the maintained ibericode/vat-rates dataset (fetched live, cached 24h) — including which rate set was in force on an optional 'date' (YYYY-MM-DD) and the names of regional exceptions (e.g. Canary Islands). Input e.g. 'DE', 'FR', 'HU'.
