## 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 2026-08-20.

- **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 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.
  - 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**: 76/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 462 tokens (~154/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**: 3/100
  - Stability observed for 1 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**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (3)

### `check_property_tax_savings` (~168 tokens)

Free check of whether a California home qualifies for a Proposition 8 decline-in-value property tax reduction. Returns a status (qualifies, fair_assessment, not_enough_data, not_residential, window_closed, county_not_served, already_filed, address_not_found, needs_more_info, busy), the current assessment, our opinion of value from recent comparable sales, and the estimated annual savings. When the property qualifies, the result includes a continueToken for start_filing. Checking is free and can only ever lower a tax bill, never raise it.

Input parameters:

- `address` (string, required): Street address including the city, for example "3746 Norris Canyon Rd, San Ramon"
- `unit` (string): Unit number for multi-unit buildings, for example "Unit 12"

### `start_filing` (~153 tokens)

Start a county filing for a property that qualified in check_property_tax_savings. Prepares the county's own review form and emails a signing link to the OWNER'S email address. The link is never returned here: the owner personally reviews, signs, and pays a flat $29 before anything is filed. Requires the continueToken from a qualifying check (valid 24 hours).

Input parameters:

- `continueToken` (string, required): The continueToken from a qualifying check_property_tax_savings result
- `ownerEmail` (string, required): Owner email; the signing link is delivered there
- `ownerName` (string, required): Owner name or names exactly as they appear on title
- `ownerPhone` (string, required): Owner daytime phone with area code

### `get_filing_status` (~59 tokens)

Coarse status of a filing by document id: awaiting_signature, awaiting_payment, filed, delivered, or unknown. Returns no personal information, addresses, or amounts.

Input parameters:

- `docId` (string, required): The docId returned by start_filing
