## 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 2026-09-20.

- **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. 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.
  - 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**: 77/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 358 tokens (~119/item across 3 items; 3 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 17/100
  - Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 95/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 83% 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)

### `fairpath_get_county_requirements` (~71 tokens)

Get FairPath County Requirements

Return public, CIE-backed county property-tax filing guidance and source metadata. This creates a private FairPath audit record but does not make a filing recommendation or change an external system.

Input parameters:

- `countyId` (string, required): FairPath county id, such as harris_tx or collin_tx.

Output parameters:

- `complianceFooter` (object)
- `confidenceLevel` (string)
- `countyCaveats` (array)
- `countyKnowledgeDensity` (object)
- `data` (object)
- `directAnswer` (string)
- `evidenceGaps` (array)
- `informationPosture` (string): Transitional compatibility field: current broker responses include it, while older broker deployments may omit it during the coordinated rollout.
- `nextAvailableFairPathAction` (object)
- `redaction` (object)
- `sourcesUsed` (array)

### `fairpath_explain_evidence_packet` (~56 tokens)

Explain A FairPath Evidence Packet

Explain the evidence categories FairPath can organize into a homeowner-reviewed property-tax evidence packet. This creates a private FairPath audit record but does not recommend a filing position, predict an outcome, or change an external system.

Output parameters:

- `complianceFooter` (object)
- `confidenceLevel` (string)
- `countyCaveats` (array)
- `countyKnowledgeDensity` (object)
- `data` (object)
- `directAnswer` (string)
- `evidenceGaps` (array)
- `informationPosture` (string): Transitional compatibility field: current broker responses include it, while older broker deployments may omit it during the coordinated rollout.
- `nextAvailableFairPathAction` (object)
- `redaction` (object)
- `sourcesUsed` (array)

### `fairpath_check_property` (~157 tokens)

Check A Consented Property

Look up a homeowner-provided address and return bounded property context. This requires explicit address consent, creates a private audit record, and may create or reuse short-lived scoped session and consent records. It does not expose owner, payment, or raw county records or change an external system.

Input parameters:

- `address` (string, required): The homeowner-provided property address to check.
- `addressConsentGranted` (boolean, required): Must be true only after the homeowner explicitly consents to address lookup.
- `consentEvidenceId` (string, required): Opaque, non-PII id for the client-side consent event. FairPath stores only its hash.
- `consentedAt` (string, required): When the homeowner explicitly approved this address lookup.
- `context` (object)

Output parameters:

- `complianceFooter` (object)
- `confidenceLevel` (string)
- `countyCaveats` (array)
- `countyKnowledgeDensity` (object)
- `data` (object)
- `directAnswer` (string)
- `evidenceGaps` (array)
- `informationPosture` (string): Transitional compatibility field: current broker responses include it, while older broker deployments may omit it during the coordinated rollout.
- `nextAvailableFairPathAction` (object)
- `redaction` (object)
- `sourcesUsed` (array)
