## 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**: 74/100
  - 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.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - 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**: 74/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 552 tokens (~138/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 47/100
  - Stability observed for 14 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 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 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).

## MCP tools (4)

### `calculate-postage` (~159 tokens)

Calculate postage

Calculates Sri Lanka Post postage for a weight, in LKR. Without a destination it prices every local service (ordinary letter, open article, parcel, speed post, logi post). With a destination country it prices every international airmail and sea mail service, with optional extras such as registration, and lists current notices for that country. Services that cannot carry the weight are left out. For cash on delivery fees use calculate-cod-fee instead.

Input parameters:

- `destination_country` (string): Destination country as an English name ("Japan") or two-letter ISO code ("JP"). Leave out to price local postage within Sri Lanka.
- `weight_grams` (number, required): Weight of the item in grams, e.g. 750 for 750 g.

### `calculate-cod-fee` (~92 tokens)

Calculate COD fee

Calculates the Sri Lanka Post cash on delivery (COD) fee for a parcel: the Logi Post courier fee for its weight, the money order commission on the amount collected, and the flat service fee. All amounts are in LKR.

Input parameters:

- `amount_lkr` (number, required): Amount the courier collects from the buyer, in LKR.
- `weight_grams` (number, required): Parcel weight in grams.

### `find-post-office` (~127 tokens)

Find post office

Finds Sri Lanka Post offices and postal codes. Search by post office name, 5-digit post code, short (tele) code, or a village or town name. Returns the post code, type, grade, whether it delivers, its division, phone numbers and, for a sub post office, the controlling post office. If no office matches the name, villages matching it are returned with the post offices serving their area.

Input parameters:

- `query` (string, required): Post office name ("Kandy"), post code ("20000"), short code, or village/town name ("Peradeniya").

### `check-prohibited-articles` (~101 tokens)

Check prohibited articles

Lists the items that are prohibited or restricted when posting from Sri Lanka to a destination country by international mail. Returns every entry for the country; compare the user's item against the descriptions yourself, as wording varies ("lithium batteries" vs "power banks"). Absence from the list is not a guarantee that an item is allowed.

Input parameters:

- `country` (string, required): Destination country, as an English name ("Australia") or two-letter ISO code ("AU").
