## 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 2026-10-18.

- **Endpoint Security**: 69/100
  - 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 enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - 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**: 78/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 1080 tokens (~98/item across 11 items; 11 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).
  - 85% 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 11 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 12 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 (11)

### `search_property` (~74 tokens)

Search for a property

Find candidate properties by address or postcode. Always call this first and confirm the match with the user before running other tools — never guess which property was meant.

Input parameters:

- `query` (string, required): Free-text address or postcode, e.g. "14 Acacia Road, CV4 7AL" or "CV4 7AL"

### `get_property_summary` (~82 tokens)

Get property summary

One-call overview of a property: EPC headline, last sale, flood risk, LPA, planning-risk score and council tax band. Start here after disambiguating with search_property.

Input parameters:

- `property_id` (string, required): The property id returned by search_property (an EPC certificate lmk-key). Prefer this over re-supplying a postcode once you have it.

### `get_epc_history` (~90 tokens)

Get EPC history

All EPC certificates lodged for a property over time, with floor area, room counts and rating per certificate. A floor-area jump between certificates with no matching planning record is the single highest-value red flag for a cash buyer.

Input parameters:

- `property_id` (string, required): The property id returned by search_property (an EPC certificate lmk-key). Prefer this over re-supplying a postcode once you have it.

### `get_price_history` (~91 tokens)

Get Price Paid history

HM Land Registry Price Paid transaction history for a property or postcode.

Input parameters:

- `address` (string): House number/name to narrow results within the postcode
- `postcode` (string): UK postcode — required if property_id is not given
- `property_id` (string): The property id returned by search_property (an EPC certificate lmk-key). Prefer this over re-supplying a postcode once you have it.

### `get_area_market` (~59 tokens)

Get area market trend

UK House Price Index and local market trend (price growth, transaction velocity, property mix) for a postcode area.

Input parameters:

- `postcode` (string, required): UK postcode or outcode, e.g. "CV4 7AL" or "CV4"

### `get_flood_risk` (~105 tokens)

Get flood risk

Environment Agency flood zone (river/sea) and surface-water risk for a property, reported separately. Returns an explicit absent state rather than a false "low" when EA has no data for the location.

Input parameters:

- `postcode` (string): UK postcode — required if property_id is not given
- `property_id` (string): The property id returned by search_property (an EPC certificate lmk-key). Prefer this over re-supplying a postcode once you have it.

### `get_planning_history` (~82 tokens)

Get planning history

Nearby planning applications and decisions, plus a rule-based planning approval-likelihood score for the area.

Input parameters:

- `postcode` (string): UK postcode — required if property_id is not given
- `property_id` (string): The property id returned by search_property (an EPC certificate lmk-key). Prefer this over re-supplying a postcode once you have it.

### `get_broadband` (~62 tokens)

Get broadband availability

Ofcom broadband and mobile coverage for a postcode. Requires a HouseData API key. Live-checked per call, so this can take several seconds — do not call it in a tight loop over many postcodes.

Input parameters:

- `postcode` (string, required): UK postcode

### `get_prism_score` (~119 tokens)

Get PRISM consent-gap score

Housedata PRISM score: identifies where a property's features (extensions, conversions, floor-area changes) lack a corresponding planning/building-control record, with remediation paths. Requires an active HouseData API key — if the account is not entitled, the error explains how to upgrade.

Input parameters:

- `postcode` (string): UK postcode — required if property_id is not given
- `property_id` (string): The property id returned by search_property (an EPC certificate lmk-key). Prefer this over re-supplying a postcode once you have it.

### `check_epc_compliance` (~69 tokens)

Check EPC / MEES compliance

Batch-checks up to 50 properties (by id or postcode) against Minimum Energy Efficiency Standard (MEES) 2030 thresholds and flags expired certificates. Use for landlord portfolio compliance sweeps.

Input parameters:

- `items` (array, required): Property ids and/or postcodes, up to 50

### `get_grants` (~114 tokens)

Get grant eligibility

Energy-efficiency and home-improvement grant schemes a property may be eligible for, based on EPC rating, council tax band, tenure and income band.

Input parameters:

- `country` (string)
- `income_range` (string)
- `postcode` (string): UK postcode — required if property_id is not given
- `property_id` (string): The property id returned by search_property (an EPC certificate lmk-key). Prefer this over re-supplying a postcode once you have it.
- `tenure` (string)

## Common questions

### What is the HouseData MCP server?

HouseData is an MCP server listed in the public MCP registry as uk.housedata/housedata. UK property data: EPC, flood risk, planning, sale prices, MEES 2030 checks and grants. This page covers its hosted endpoint (https://housedata.uk/mcp).

### Is the HouseData MCP server safe to use?

HouseData scores 72 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the HouseData MCP server expose?

HouseData exposes 11 tools: search_property, get_property_summary, get_epc_history, get_price_history, get_area_market, and 6 more. Their descriptions and schemas cost roughly 947 tokens of context every time the server is loaded.

### Does the HouseData MCP server require authentication?

No. We connected to HouseData without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the HouseData MCP server still maintained?

HouseData is still listed as active in the MCP registry. We last reached this channel on 18 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
