## 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 2026-09-27.

- **Endpoint Security**: 57/100
  - 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 3 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.
  - 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 (excellent).
  - Context-footprint check failed: tool/resource definitions use about 767 tokens (~255/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 63/100
  - Stability observed for 19 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.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 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 (3)

### `wa_reet` (~194 tokens)

Washington REET calculator

Calculate Washington State Real Estate Excise Tax (REET, RCW 82.45) for one sale: graduated state brackets plus the county's local rate, computed deterministically by SENTINEL's production engine — never estimated. Use when you need the exact excise tax owed on a WA home sale (seller-paid by default). Washington State counties only. The result includes the per-bracket breakdown, the $5 DOR technology fee, and rate-assumption caveats (verify the DOR location code for city-level exceptions). Uses no third-party data. The result includes an 'attributions' array (upstream source lines and the NWMLS/DOR/county non-affiliation line) and a professional-advice disclaimer — pass both through to end users.

Input parameters:

- `county` (string): Washington county the property sits in (lowercase).
- `salePrice` (integer, required): Contract sale price in whole US dollars.

Output parameters:

- `attributions` (array)
- `county` (string)
- `disclaimer` (string)
- `effective_rate_pct` (number)
- `estimated_total_due` (integer): total_reet + technology_fee.

### `wa_net_sheet` (~243 tokens)

Washington seller net sheet

Estimate a Washington home seller's net proceeds: commission, graduated REET, title/escrow/closing costs, mortgage payoff, and optional HOA/tax prorations — every line item computed deterministically by the same engine SENTINEL's product uses. Use for 'what will the seller walk away with' questions on WA sales; WA counties only. The result is an itemized dict. Uses no third-party data. The result includes an 'attributions' array (upstream source lines and the NWMLS/DOR/county non-affiliation line) and a professional-advice disclaimer — pass both through to end users.

Input parameters:

- `commissionRate` (number): Total commission as a decimal fraction (0.05 = 5%). Defaults to the NWMLS-typical rate.
- `county` (string): Washington county the property sits in (lowercase).
- `hasHoa` (boolean): Include HOA transfer/resale-cert fees.
- `mortgageBalance` (integer): Outstanding mortgage payoff in dollars.
- `propertyTaxProration` (integer): Seller-side property-tax proration, dollars.

- `state_reet_brackets_effective_through` (string)
- `title_insurance` (integer)
- `total_costs` (integer)
- `total_deductions` (integer)
- `total_reet` (integer)

### `nwmls_deadlines` (~269 tokens)

NWMLS deadline calculator

Compute the standard NWMLS transaction deadline set from a mutual-acceptance date: earnest money (Form 21), seller disclosure delivery + buyer rescission (Form 17, RCW 64.06), title contingency (Form 22T), inspection (Form 35), financing (Form 22A), and FIRPTA certification (Form 22E). Business-day counts exclude weekends and Washington state holidays per RCW 1.16.050 — never plain calendar arithmetic. Washington/NWMLS transactions only. Dates are the standard form DEFAULTS computed from public rules (no NWMLS data or form text); the result flags dates landing on non-business days and includes a verify-against-the-executed-contract disclaimer that must accompany any advice built on these dates. The result includes an 'attributions' array (upstream source lines and the NWMLS/DOR/county non-affiliation line) and a professional-advice disclaimer — pass both through to end users.

Input parameters:

- `closing`: Optional contract closing date (on/after mutual acceptance), ISO YYYY-MM-DD.
- `financingDays` (integer): Form 22A financing-contingency length.
- `mutualAcceptance` (string, required): Mutual acceptance date, ISO YYYY-MM-DD (within 5 years of today).

Output parameters:

- `attributions` (array)
- `deadline_disclaimer` (string)
- `deadlines` (array)
- `disclaimer` (string)
- `financing_days` (integer)
- `mutual_acceptance` (string)
