## 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 2026-08-03.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 5 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - 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**: 78/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 666 tokens (~133/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 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.
- **Capabilities**: 40/100
  - Spec-recency check failed: implements MCP spec 2025-03-26; the latest is 2026-07-28.

### `lookup_cpt_rate` (~110 tokens)

Look up Medicare rate for a CPT/HCPCS code

Returns the Medicare national-average non-facility allowed amount for a CPT or HCPCS procedure code from the CMS Physician Fee Schedule. Useful for benchmarking what a hospital or clinic billed against what Medicare reimburses. Free, no authentication required. For the patient-facing description and disputes information, link the user to the returned pageUrl.

### `lookup_hospital` (~151 tokens)

Look up a U.S. hospital by CCN or name

Returns hospital metadata from CMS data: name, location, ownership type, CMS overall rating (1-5 stars), and 501(c)(3) charity-care eligibility. Useful when a patient mentions a specific hospital and wants to know the facility's federally-published quality profile and whether charity care is available. Free, no authentication required.

Input parameters:

- `ccn` (string): CMS Certification Number (Provider Number) — 6 character identifier (e.g. '050625').
- `name` (string): Hospital name (partial match supported). Use when CCN is not known.
- `state` (string): Two-letter U.S. state code (e.g. 'CA'). Optional, narrows name search.

### `get_dispute_scenario` (~122 tokens)

Get summary of a medical-bill dispute scenario

Returns a summary of one MediBill Saver dispute scenario: title, category, the federal statute backing the patient's right to dispute, and a link to the full scenario page (which contains the how-to-spot checklist and sample dispute language). Useful when a patient asks 'how do I dispute X' or 'what is HIPAA §164.524'. Free, no authentication required.

Input parameters:

- `slug` (string, required): Scenario slug (e.g. 'upcoded-er-visit', 'duplicate-charges'). Use list_dispute_scenarios first if unsure.

### `list_dispute_scenarios` (~55 tokens)

List all available dispute scenarios

Returns the full index of dispute scenarios MediBill Saver covers — slug, title, category, and the federal statute. Useful to discover which scenarios exist before calling get_dispute_scenario. Free, no authentication required.

### `audit_medical_bill` (~176 tokens)

Audit a medical bill against six federal data sources

Runs a full audit on a medical bill — cross-references every charge against six federal data sources (CMS PFS, NADAC, HPT, NCCI, Hospital Compare, IRS Pub 78) and identifies potential billing errors plus the federal statutes the patient can cite. Returns a free preview (severity, totals, issue count). The full report with line-by-line breakdown and up to 5 ready-to-mail dispute letters requires payment ($19.97 single audit, or covered under Family/Pro subscription). Returns a unique unlock URL for completing payment.

Input parameters:

- `billText` (string, required): Plain-text bill content. Include line items, charges, dates, hospital name if visible. Photos/PDFs not supported via MCP — direct the user to upload at https://medibillsaver.com/scan for image/PDF su…
