## Findings

No check matched anything in these tool definitions.


## Changes things (8)

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

### `ppd_transactions`

- 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
Land Registry Price Paid transactions for a postcode, most recent first.

Returns up to `limit` most recent transactions **within snapshot coverage**
(`coverage_from`-`coverage_to` in the response's `provenance`).
Unfiltered by default -- category-B bulk transfers and commercial sales are
included. Pass `property_type` (F=flat, D=detached, S=semi, T=terraced,
O=other) to restrict the result to a single type.

**Not a complete property history.** Check `provenance.older_records_exist`
and `provenance.sample_complete` before saying anything about what a
property has or has not sold for. An empty result means "no sales within
the stated coverage" -- never "never sold". For clean residential
comparable sales, use `property_comps`.
```

### `property_blocks`

- 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
Property block analysis — identify buildings with multiple flat sales (block-buy opportunities).
```

### `property_comps`

- 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
Comparable sales from Land Registry Price Paid Data.

Defaults return the standard residential set:
- property_type=None means residential (F+D+S+T). Pass "F"/"D"/"S"/"T"/"O"
  for a single type, or "ALL" to disable type filtering (firehose).
- transaction_category defaults to "A" (standard sales). Pass None to
  include category-B (bulk transfers, non-standard conveyances).
- filter_outliers=False by default; set True for IQR-trimmed stats AND
  transaction list (1.5*IQR rule, needs >=4 prices).

limit caps returned transactions (max 200). enrich_epc attaches EPC floor
area and price-per-sqft to each transaction — slower but richer.
```

### `property_epc`

- 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
Energy Performance Certificate data for a UK property or postcode area.

With address: returns the matched EPC certificate for that specific property.
Without address: returns the record count and, when the bounded response
contains every matching summary, the rating distribution. Property-type
breakdown and floor-area statistics are NOT available — the EPC service
exposes them only on individual certificates.

Returns null only when no certificates are lodged for the postcode. A null result means no such certificate is lodged. If the EPC service cannot be reached the tool raises an error instead — never treat an error as evidence that a property has no certificate.
```

### `property_yield`

- 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
Gross rental yield for a UK postcode.

Combines Land Registry sale comps (median sale price) with Rightmove rental
listings (median monthly rent) to produce a gross yield percentage.
```

### `rental_analysis`

- 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
Rental market analysis and achievable rent estimate.

auto_escalate widens the Rightmove search RADIUS when fewer than 5 listings
are found (thin market). This is rental-radius escalation and is unaffected
by the PPD geography containment: it does not change a postcode's outcode or
sector, so it carries none of the limit-dependence that disabled PPD
auto-widening. Response includes thin_market, escalated_from, escalated_to
fields when escalation occurs.
```

### `rightmove_listing`

- 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
Full detail for a single Rightmove listing.

property_id is the numeric Rightmove property ID (the digits at the end of a
rightmove.co.uk/properties/... URL), max 12 digits. Full URLs are not accepted.
include_images fetches and embeds photos and floorplans as MCP image content.
max_images caps the number of property photos (default 3); floorplans always included.
```

### `stamp_duty`

- 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
UK Stamp Duty Land Tax (SDLT) calculation with full breakdown.
```

## Only reads (6)

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

### `company_search`

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

Description, as the server wrote it:

```untrusted-server-text
Search Companies House for a company by name.
```

### `epc_certificate`

- The description's first verb is "fetch": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch a single EPC certificate by its GOV.UK certificate number.

Use after property_epc_summaries has listed the candidates and you have
picked one — this is faster than property_epc(postcode, address) as it makes
a direct lookup with no address matching or postcode re-fetch.

The parameter is named lmk_key as a compatibility alias; pass the
certificate number, which is returned in every property_epc_summaries row.
(property_epc_search is deprecated and raises — do not call it.)

Returns the full EPC certificate, or null only when no such certificate is lodged. A null result means no such certificate is lodged. If the EPC service cannot be reached the tool raises an error instead — never treat an error as evidence that a property has no certificate.
```

### `planning_search`

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

Description, as the server wrote it:

```untrusted-server-text
Find the council planning portal URL for a postcode.
```

### `property_epc_search`

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

Description, as the server wrote it:

```untrusted-server-text
DEPRECATED — use property_epc_summaries then epc_certificate.

This tool returned score, floor_area, property_type, habitable_rooms and
inspection_date for every certificate at a postcode. The EPC service no
longer exposes those fields in a search: they exist only on a full
certificate. Reproducing the old response would require one upstream
request per certificate, so this tool is unsupported rather than silently
degraded or silently expensive.
```

### `property_epc_summaries`

- The description's first verb is "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List EPC certificate summaries at a postcode — for candidate selection.

Returns one bounded page. Each entry contains only what the EPC search
exposes: certificate_number, address, uprn (often absent), energy band,
registration_date and schema_type. Energy score, floor area and property
type are NOT available here — fetch a specific certificate for those.

Workflow when a Rightmove listing has no house number:
  1. property_epc_summaries(postcode) to list candidates.
  2. Narrow by address text and, where present, uprn.
  3. epc_certificate(lmk_key=<certificate_number>) for the chosen one, then
     cross-check its floor_area against the listing.
  4. If several candidates remain equally plausible, present them all —
     do not guess. Selecting arbitrarily attaches another property's data.

`complete` is false when the postcode holds more records than this page
returns. Upstream page traversal is not snapshot-stable, so a multi-page
result is a bounded sample, not a guaranteed-complete set.

An empty `results` list means no certificates are lodged. If the EPC service
cannot be reached the tool raises an error instead — never treat an error as
evidence that a property has no certificate.
```

### `rightmove_search`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch Rightmove listings for a postcode.

listing_type: "sale" or "rent". sort_by: "newest", "most_reduced",
"price_asc", "price_desc". Images are excluded from results.
```
