MCP tools · 10 exposed · ~875 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
check_email_domain ~70

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.

NameTypeReqDescription
email_or_domainstringyes–

No output schema declared.

No examples provided.

payout_reconciliation ~94

Explain why a payout is less than sales: walk gross -> deductions -> expected, and (if actual_deposit given) flag the unexplained gap (shortfall/surplus).

gross_salesnumberyes–

reorder_point ~70

Reorder point = lead-time demand + safety stock. If on_hand is given, returns whether to reorder now and the days of cover remaining.

No output schema declared.

stripe_connect_split ~152

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 ~56

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.

NameTypeReqDescription
routing_numberstringyes–

No output schema declared.

No examples provided.

validate_eori ~88

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).

NameTypeReqDescription
eoristringyes–

No output schema declared.

No examples provided.

validate_eu_vat ~111

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).

NameTypeReqDescription
vat_numberstringyes–

No output schema declared.

No examples provided.

validate_gtin ~60

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.

NameTypeReqDescription
codestringyes–

No output schema declared.

No examples provided.

validate_iban ~64

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.

NameTypeReqDescription
ibanstringyes–

No output schema declared.

No examples provided.

vat_rate_by_country ~110

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'.

Install

How do I install the org.scienceswarm/commerce-validators MCP server?

org.scienceswarm/commerce-validators is a hosted endpoint at https://mcp.scienceswarm.org/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

Is the org.scienceswarm/commerce-validators MCP server safe to use?

org.scienceswarm/commerce-validators scores 18 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

org.scienceswarm/commerce-validators exposes 10 tools: validate_iban, validate_gtin, validate_aba_routing, validate_eu_vat, validate_eori, and 5 more. Their descriptions and schemas cost roughly 875 tokens of context every time the server is loaded.

Does the org.scienceswarm/commerce-validators MCP server require authentication?

Its publisher declares no required credentials for org.scienceswarm/commerce-validators. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.

Is the org.scienceswarm/commerce-validators MCP server still maintained?
