Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security46
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to connect, but we couldn't read the tool list to see what that exposes. View diagnostics → Unverified
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 530, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability0
- Transport check failed: declared streamable-http, but the endpoint returned HTTP 530. See how to fix → View diagnostics → Fail
Schema Quality & AI Usability0
- Schema not yet verified: we couldn't read the endpoint's schema.Unverified
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage0
- Tool coverage not yet verified: we couldn't read the endpoint's tools.Unverified
Tool Safety0
- Tool safety not yet verified: we couldn't read the endpoint's tools.Unverified
Capabilities0
- Capabilities not yet verified: we couldn't read the endpoint's capabilities.Unverified
Unverified: 5 categories
Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.
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.

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 →
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.
| Name | Type | Req | Description |
|---|---|---|---|
| email_or_domain | string | yes | – |
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).
| Name | Type | Req | Description |
|---|---|---|---|
| actual_deposit | – | – | – |
| chargebacks | number | – | – |
| gross_sales | number | yes | – |
| other_deductions | number | – | – |
| processing_fees | number | – | – |
| refunds | number | – | – |
No output schema declared.
No examples provided.
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.
| Name | Type | Req | Description |
|---|---|---|---|
| avg_daily_sales | number | yes | – |
| lead_time_days | number | yes | – |
| on_hand | – | – | – |
| safety_stock | number | – | – |
No output schema declared.
No examples provided.
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.
| Name | Type | Req | Description |
|---|---|---|---|
| application_fee_fixed | number | – | – |
| application_fee_pct | number | – | – |

No output schema declared.
No examples provided.
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.
| Name | Type | Req | Description |
|---|---|---|---|
| routing_number | string | yes | – |
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).
| Name | Type | Req | Description |
|---|---|---|---|
| eori | string | yes | – |
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).
| Name | Type | Req | Description |
|---|---|---|---|
| vat_number | string | yes | – |
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.
| Name | Type | Req | Description |
|---|---|---|---|
| code | string | yes | – |
No output schema declared.
No examples provided.
validate_iban ~64

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'.
| Name | Type | Req | Description |
|---|---|---|---|
| country_code | string | yes | – |
| date | string | – | – |
No output schema declared.
