## 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**: 77/100
  - 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 is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 64/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 2527 tokens (~315/item across 8 items; 8 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **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 8 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 9 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 (8)

### `get_products` (~218 tokens)

Get the HOUSINGFAX report and its consent text

Returns the HOUSINGFAX report for a home in Spain (productMode free): a single product, the full report with web view and PDF, free of charge, with the building condition assessment when the building has an IEE/ITE record. Also returns the capacity limits of the channel (no daily cap) and the consent text (with its SHA-256) that the person must accept before create_free_report. Use it when someone asks what HOUSINGFAX offers or before ordering. Always tell the person: it is a preliminary, automated report built from public records, not a technical inspection, valuation, certificate, safety assessment or legal advice; probabilities are given as words (very low to very high), never as percentages; a check without data (○) means unknown, not negative or safe; Navarra is not covered yet; the report is only available as a private link.

Input parameters:

- `language` (string): Language of the texts in the answer (and of the report): es, en, de, nl or fr. Default es.

Output parameters:

- `capacity` (object)
- `checksCount` (integer)

### `list_checks` (~182 tokens)

List the checks of the HOUSINGFAX report

Lists the 22 numbered checks of the report (title, question it answers and whether its source is integrated yet) and the meaning of the ✓ / ⚠ / ○ marks. Use it to explain what the report looks at. Checks marked pending_integration show as ○ no data, never as a negative result. Always tell the person: it is a preliminary, automated report built from public records, not a technical inspection, valuation, certificate, safety assessment or legal advice; probabilities are given as words (very low to very high), never as percentages; a check without data (○) means unknown, not negative or safe; Navarra is not covered yet; the report is only available as a private link.

### `check_coverage` (~227 tokens)

Check whether a Spanish province or municipality is covered

Says whether HOUSINGFAX can produce a report for a province (name or two-digit INE code) and, optionally, finds the municipality in the official street directory. Status covered, not_yet_covered (Navarra: foral adapter pending) or unrecognized; not_yet_covered never means no risk. In the Basque Country (Araba, Bizkaia, Gipuzkoa) the report covers the whole building, not a single flat. municipalityLookup unavailable means the directory did not answer: unknown, not missing. Call it before search_address when you are not sure the place is covered.

Input parameters:

- `language` (string): Language of the texts in the answer (and of the report): es, en, de, nl or fr. Default es.
- `municipality` (string): Optional municipality name; it is looked up in the official street directory of the province.

Output parameters:

- `contract` (string)
- `coverageNote` (string)
- `language` (string)
- `municipalities`
- `municipalityLookup` (string)
- `provinces` (array)

### `search_address` (~291 tokens)

Search a municipality or street in the official directory

Two steps to build an address. kind=municipality with provinceCode and q returns municipalities and their codes. kind=street with provinceCode, municipalityDgcCode, municipalityIneCode (from the first step) and q returns streets with streetTypeCode and streetCode (and localityId in the Basque Country). Pass the chosen street, the house number and the codes to resolve_building. Only for places check_coverage reports as covered. Do not store or publish the address.

Input parameters:

- `kind` (string, required): municipality (step 1) or street (step 2).
- `language` (string): Language of the texts in the answer (and of the report): es, en, de, nl or fr. Default es.
- `municipalityDgcCode` (string): Only with kind=street: municipalityDgcCode from step 1.
- `municipalityIneCode` (string): Only with kind=street: municipalityIneCode from step 1.
- `provinceCode` (string, required): Two-digit INE province code (e.g. 28 Madrid, 08 Barcelona).
- `q` (string, required): Text to search: municipality name, or street name optionally followed by the number ("Colón, 5").
- `streetTypeCode` (string): Only with kind=street, optional: street type code to narrow the search (CL, AV, PZ…).

Output parameters:

- `contract` (string)
- `kind` (string)
- `language` (string)
- `numberHint` (string)
- `options`

### `resolve_building` (~321 tokens)

Identify the building or flat to report on

Identifies the building from an address found with search_address (object address) or from a cadastral reference (14 characters = building or plot; 18 or 20 = a single flat). Give either cadastralReference or address, not both. status resolved returns a resolutionToken (valid 15 minutes) for create_free_report, the building's public cadastral data and whether an IEE/ITE record exists (ieeAvailability; unverified means the registry did not answer, not that there is none), which decides whether the report includes the building condition assessment. status select_unit lists the units: ask the person which flat, or repeat with the 14-character reference and scope=building for the whole building. Only non-protected cadastral data is returned. Do not publish the address or reference.

Input parameters:

- `address` (object): Coded address from search_address (provinceCode, municipalityDgcCode, municipalityIneCode, streetTypeCode, streetCode, number; localityId in the Basque Country; optional block, stair, floor, door). U…
- `cadastralReference` (string): Cadastral reference: 14 characters (building or plot), 18 or 20 (a flat). Use instead of address.
- `language` (string): Language of the texts in the answer (and of the report): es, en, de, nl or fr. Default es.
- `scope` (string): Only with a 14-character cadastralReference: building to report on the whole building.

- `notice` (string)
- `resolutionExpiresInSeconds`
- `resolutionToken`
- `status` (string)

### `create_free_report` (~402 tokens)

Create the HOUSINGFAX report (private link)

Queues the report for the building resolved with resolve_building and returns a private link (previewUrl) and a statusToken for get_report_status. Every report is free: it is the full report with PDF, with the building condition assessment when the building has an IEE/ITE record, generated in minutes. CONSENT: before calling, show the person the consent text returned by get_products (consent.text, same language) with its terms and privacy links, and set consent=true only if the person has explicitly accepted it in this conversation; pass consent.statementSha256 as consentStatementSha256. Never accept on the person's behalf. The email is optional (ready notice with the link and the PDF) and only with the person's permission. If the answer is CHANNEL_AT_CAPACITY or CLIENT_LIMIT, wait the retryAfterSeconds it gives and try again. The link is private: give it only to the person, never publish it. Always tell the person: it is a preliminary, automated report built from public records, not a technical inspection, valuation, certificate, safety assessment or legal advice; probabilities are given as words (very low to very high), never as percentages; a check without data (○) means unknown, not negative or safe; Navarra is not covered yet; the report is only available as a private link.

Input parameters:

- `consent` (boolean, required): true only if the person explicitly accepted the consent text from get_products.
- `consentStatementSha256` (string, required): consent.statementSha256 from get_products for the same language.

Get the status of a HOUSINGFAX report

Returns the status of a report created with create_free_report: queued, in_progress, ready, failed or expired, with the private link when ready. Wait pollAfterSeconds between calls. withLimitations=true means some source did not answer and its check shows ○ no data with the reason (unknown, not negative). Give the link only to the person.
