Category Maps and Location
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 Security74
- 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
- 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 Usability74
- AI-judged instruction clarity (good).Pass
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management47
- Stability observed for 14 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 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 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 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 →
calculate-cod-fee Calculate COD fee ~92
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.
| Name | Type | Req | Description |
|---|---|---|---|
| amount_lkr | number | yes | Amount the courier collects from the buyer, in LKR. |
| weight_grams | number | yes | Parcel weight in grams. |
No output schema declared.
No examples provided.
calculate-postage Calculate postage ~159
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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 | yes | Weight of the item in grams, e.g. 750 for 750 g. |
No output schema declared.
No examples provided.
check-prohibited-articles Check prohibited articles ~101
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.
| Name | Type | Req | Description |
|---|---|---|---|
| country | string | yes | Destination country, as an English name ("Australia") or two-letter ISO code ("AU"). |
No output schema declared.
No examples provided.
find-post-office Find post office ~127
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.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | yes | Post office name ("Kandy"), post code ("20000"), short code, or village/town name ("Peradeniya"). |
No output schema declared.
No examples provided.
