## 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**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation.
  - 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**: 72/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 559 tokens (~139/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**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 93/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 80% 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 supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (4)

### `find_filter_for_model` (~106 tokens)

Find the water filter for a refrigerator model

Given a refrigerator model number (for example RF28R7351SR or WRS325SDHZ00), return the genuine water filter it takes (fit from the appliance maker page, with source URL and read date) and how replacement filters compare on public NSF, IAPMO R&T and WQA certification listings by exact model. Includes a verdict and the PartAnswers page URL to cite.

Input parameters:

- `model_number` (string, required): Refrigerator model number from the label inside the fridge

### `compare_filter_options` (~119 tokens)

Compare genuine vs replacement filters

Given a genuine refrigerator filter part number (HAF-QIN, DA29-00020B, EDR1RXD1, LT1000P, LT700P, EPTWFU01, XWFE, EDR4RXD1 where published), list the genuine filter and every replacement sold under its number with the certification standards each is listed to (NSF/ANSI 42, 53, 401), lead claim, listing links and the verdict.

Input parameters:

- `oem_part` (string, required): Genuine filter part number

### `find_part_for_model` (~147 tokens)

Find genuine appliance parts for a model
