## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 61/100
  - AI-judged instruction clarity (good).
  - 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.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 67/100
  - Stability observed for 20 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 13 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 14 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

Order a free postal pack (Bosca) for the user

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.

Input parameters:

- `consent_contact` (boolean, required): Must be true: the person agrees to be emailed about the pack and contacted about their items
- `county` (string, required): County in the Republic of Ireland, e.g. Cork, Mayo, Dublin (Northern Ireland addresses are refused with the alternative)
- `eircode` (string, required): The person's Eircode, 7 characters, e.g. D02 X285 (finder.eircode.ie)
- `email` (string, required): The person's own email: the receipt, the offer and every update go there
- `estimated_value_eur` (number): Rough total value in euro; ask for it. It sets the value band on the request and the route: gold up to 2,000 euro goes straight to a pack, lots over 2,000 euro are arranged on WhatsApp, and under 300…
