## 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**: 63/100
  - 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 enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - 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**: 65/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 967 tokens (~241/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**: 57/100
  - Stability observed for 17 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)

### `list_guides` (~120 tokens)

List the appeal guides

Lists Claim Back’s guides (US), each with its slug, title, one-line summary and link. Medicare Advantage: how to appeal and who can ask, the appeal deadline, a prior authorization denial, the fast appeal when care is ending, care ended or denied because the patient stopped improving (the maintenance standard), and the independent review. Long-term care insurance: what to do after a denial, and the independent review of benefit-trigger denials state by state. Use it to find the guide that answers the user’s question, then read_guide.

### `read_guide` (~79 tokens)

Read an appeal guide

Returns one guide in full as Markdown, with its sources (federal and state regulations, Medicare.gov, CMS and state insurance departments). Use it to answer questions about Medicare Advantage appeals and long-term care insurance claim denials accurately, and link the guide in the answer.

Input parameters:

- `slug` (string, required): The guide’s slug, from list_guides.

### `appeal_deadline` (~233 tokens)

Work out an appeal deadline

Calendar arithmetic for Medicare Advantage appeal deadlines. Give notice_date (the date printed on the plan’s denial notice) for the plan reconsideration deadline: 65 days from that date (the rule is 60 days from receipt, presumed 5 days after the date). Or give care_end_date (the date covered skilled nursing, home health or outpatient rehab care ends, on the Notice of Medicare Non-Coverage), and notice_delivered_date (the day that notice was handed over) if known, for the fast appeal: by noon of the day after delivery; without the delivery date, noon the day before the end date, which holds only for a notice that came two days ahead. The notice’s own instructions come first.

Input parameters:

- `care_end_date` (string): The date covered care ends, from the Notice of Medicare Non-Coverage, YYYY-MM-DD.
- `notice_date` (string): The date printed on the denial notice, YYYY-MM-DD.
- `notice_delivered_date` (string): The day the Notice of Medicare Non-Coverage was delivered, YYYY-MM-DD (with care_end_date).

### `claim_back_services` (~103 tokens)

Claim Back’s services and prices

How Claim Back helps with a Medicare Advantage appeal, and what it costs: a free check of the denial letter, then two fixed-price services (we handle it for you, paid only if the decision is reversed; or we prepare it and you send it). It also says what Claim Back offers for a long-term care insurance claim denial. Returns the link where the user uploads their letter. Use it when the user wants help with an appeal or asks about Claim Back.
