## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, 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)

## MCP tools (3)

### `ca_rx_wac_increases` (~335 tokens)

California manufacturer disclosures of a prescription drug's Wholesale Acquisition Cost (WAC — the published list price before rebates/discounts) going UP. Required by California law (SB 17/AB 265) whenever a drug's WAC exceeds $40 for a course of therapy AND the increase exceeds the statutory cumulative threshold; filed with HCAI's Cost Transparency Rx (CTRx) program. Search by drug name/fragment, manufacturer, or NDC, optionally pinned to one report year (2019-present; omit to search every year). Returns each increase's amount, the WAC after the increase, and whether the record comes from the still-open current year or a closed annual archive. This is the LIST price a manufacturer sets, not what any payer or pharmacy actually pays — for that, see the drug-prices pack's nadac_price/asp_payment_limit tools. California-only: see the pack README for which other states publish this and in what form. Keyless.

Input parameters:

- `drug` (string): Drug name or fragment, e.g. "Humira", "insulin glargine", matched against the drug product description.
- `limit` (number): Max records to return, 1-100 (default 25).
- `manufacturer` (string): Manufacturer name or fragment, e.g. "AbbVie", "Novo Nordisk".
- `ndc` (string): National Drug Code, any common format.
- `year` (string): Report year, "2019".."2026". Omit to search every available year (recommended for a single drug/manufacturer/NDC lookup).

### `ca_rx_wac_five_year_history` (~183 tokens)

The 5-year WAC increase history California requires manufacturers to disclose alongside each WAC Increase Report — every prior increase for that NDC over the preceding 5 calendar years, with its date and amount. Use this to see a drug's full price trajectory rather than just its latest jump (ca_rx_wac_increases). Lookup is by NDC (get one from ca_rx_wac_increases first if you only have a drug name). Part of HCAI's CTRx program. California-only. Keyless.

Input parameters:

- `limit` (number): Max history rows to return, 1-200 (default 50).
- `ndc` (string, required): National Drug Code, any common format.
- `year` (string): Report year to pin to, "2019".."2026". Omit to search every available year.

### `ca_rx_new_drug_launches` (~242 tokens)

California manufacturer disclosures of a NEW prescription drug launched with a Wholesale Acquisition Cost (WAC — published list price) exceeding the Medicare Part D specialty-drug cost threshold — California's "launch price" transparency requirement, filed with HCAI's Cost Transparency Rx (CTRx) program (same law as ca_rx_wac_increases, different trigger: a NEW drug's starting price rather than an existing drug's price increase). Search by drug name/fragment or manufacturer, optionally pinned to one report year (2019-present). Returns the launch WAC, estimated patient population, and breakthrough-therapy/priority-review FDA designations when disclosed. California-only. Keyless.

Input parameters:

- `drug` (string): Drug name or fragment, e.g. "Vraylar", "Opdualag".
- `limit` (number): Max records to return, 1-100 (default 25).
- `manufacturer` (string): Manufacturer name or fragment, e.g. "AbbVie", "Bristol Myers Squibb".
- `year` (string): Report year, "2019".."2026". Omit to search every available year.
