## Findings

No check matched anything in these tool definitions.


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `check_epc_compliance`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Only reads (10)

Looks things up and changes nothing. Claude Code: allow.

### `get_area_market`

- The name "get_area_market" says "get": a word for reading.

Description, as the server wrote it:

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

### `get_broadband`

- The name "get_broadband" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `get_epc_history`

- The name "get_epc_history" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `get_flood_risk`

- The name "get_flood_risk" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `get_grants`

- The name "get_grants" says "get": a word for reading.

Description, as the server wrote it:

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

### `get_planning_history`

- The name "get_planning_history" says "get": a word for reading.

Description, as the server wrote it:

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

### `get_price_history`

- The name "get_price_history" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
HM Land Registry Price Paid transaction history for a property or postcode.
```

### `get_prism_score`

- The name "get_prism_score" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `get_property_summary`

- The name "get_property_summary" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `search_property`

- The name "search_property" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.
```
