## 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 2026-10-03.

- **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**: 73/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 564 tokens (~188/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 53/100
  - Stability observed for 16 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 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (3)

### `find_drug` (~132 tokens)

Find a drug

Resolve free-text drug wording (brand or generic, English or Spanish) to the canonical LowerScript/RxSense drug: its known dosage forms, strengths, and a typical fill quantity. Cost/availability lookup only — never a substitute drug, never a dose recommendation, never priced (use get_prices for a price). Returns a "try another name" message when nothing matches.

Input parameters:

- `language` (string): Response language. Defaults to English.
- `query` (string, required): Drug name in English or Spanish, brand or generic (e.g. "metformin", "Ozempic", "amoxicilina").

### `get_prices` (~341 tokens)

Get pharmacy prices

Live cash prices for one drug at nearby pharmacies (up to 10, cheapest first, full spread shown — not just the lowest), using the LowerScript discount network (RxSense). Carries the LowerScript card codes, a wallet-pass link, and the lowerscript.com page for the same answer. One drug per call — no bulk lookups. Requires a 5-digit US ZIP in a state LowerScript currently serves (FL, TX, AZ, NC, SC, GA, IL, CA); city/state alone is not yet supported. Cost and pharmacy information only — refuses any clinical question (dose, safety, interactions, pregnancy, starting or stopping a medicine) with no price.

Input parameters:

- `city` (string): Optional city name, for context only. Does not replace zip — a price lookup still needs a 5-digit ZIP.
- `drug` (string, required): Drug name, English or Spanish, brand or generic.
- `form` (string): Optional dosage form, e.g. "tablet", "capsule", "pen", "inhaler".
- `language` (string): Response language. Defaults to English.
- `quantity` (number): Optional fill quantity. Defaults to a typical fill size for the drug's own form (e.g. 30 tablets; 1 pen/inhaler).
- `state` (string): Optional 2-letter US state, for context only. Does not replace zip.
- `strength` (string): Optional strength, e.g. "500 mg".
- `zip` (string, required): 5-digit US ZIP code. Required for a price — city/state alone cannot be geocoded by this tool yet.

### `get_card` (~91 tokens)

Get the LowerScript card

The static LowerScript discount card: RxBIN/RxPCN/RxGRP codes, how to use it at the pharmacy counter, wallet-pass and card-page links, member support, and the exact compliance wording (not insurance, up to 80%). No lookup involved — always the same answer for a given language.

Input parameters:

- `language` (string): Card language / RxGRP network. Defaults to English.
