## 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**: 74/100
  - 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.
  - 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**: 66/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 391 tokens (~195/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 30/100
  - Stability observed for 9 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 2 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**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (2)

### `find_dentist` (~264 tokens)

Dental prices and NHS places near a postcode

What practices near a London postcode district charge for a treatment, lowest first, read by hand from each practice's own price list, with the NHS charge and which nearby practices say they are taking new NHS patients. Covers Tower Hamlets, Hackney, Southwark, Newham, City of London, Islington, Lewisham, Waltham Forest, Haringey, Redbridge, Greenwich and Barking and Dagenham so far. Every price carries its source page and the date it was read. Always pass on the urgent-care line.

Input parameters:

- `max_miles` (number): How far from the middle of the district. Default 2, the same as toothache.fyi's treatment pages. 1 is walking distance, 6 a short drive.
- `max_price` (number): Budget in pounds. Optional.
- `postcode` (string, required): The first half of a UK postcode (the district), e.g. "E14" or "EC1M". Send only that: a full postcode works but only the first half is used.
- `treatment` (string, required): What the person needs. "emergency" for pain now; "checkup" if unsure; "implant" means the implant and its crown for one tooth.

### `nhs_charges` (~40 tokens)

NHS dental charges in England

The NHS dental charge bands in England, what each covers, who is exempt, and how to get urgent care, to compare with a private quote.
