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 Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- 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 Usability61
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 2914 tokens (~224/item across 13 items; 13 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management67
- Stability observed for 20 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 13 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 14 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

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 →

request_postal_pack Order a free postal pack (Bosca) for the user ~822
Orders a free insured postal pack for a person at a Republic of Ireland address and returns the Bosca number. This is the real order: the request is created when you call it, and for gold lots within the postal limits the pack is posted to the address given with no further step from the person. Silver, mixed lots, bullion and lots over 2,000 euro are registered and arranged on WhatsApp instead; the response says which happened. The person gets a receipt email with a single-use cancel link. Before calling: have the person's name, full address with Eircode, email, phone, what they are sending (gold, silver or mixed) with a rough description and rough value, their agreement to be contacted, and their agreement to the terms statement in accepts_terms. Explain the process first (get_postal_pack_info): items weighed and XRF tested on camera, an itemised offer at the live published rate on the day of testing (no payout is promised), free tracked return if they decline, insured in transit up to 2,000 euro, paid by bank transfer the same day they accept, one photo ID checked before payment. Lots worth more than 1,000 euro can be brought to us in person in Dublin, by appointment, and tested while you watch; message us on WhatsApp to arrange a time. Smaller lots go by post. Do not collect or pass ID documents. Errors name the field to fix.
