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 →
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 call this server, and 10 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS not yet verified: we couldn't determine whether a plaintext access path exists. 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 & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability66
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 875 tokens (~87/item across 10 items; 10 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
- Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage67
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

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 | — | — |
| charge_amount | number | yes | — |

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).

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.
