## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `check_rental_postcode`

- 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
Area facts for a postcode in England, when no particular home is given (for a specific address use run_free_check): the average private rent for the council (ONS), Local Housing Allowance rates, whether a council property licensing scheme covers the area, flood risk and the nearest stations. Use it when someone is renting, viewing or about to sign for a home in England and gives a postcode. Share the links it returns: the free property check for the exact address, and Complete RenterCheck, which compares the rent, checks the owner and the tenancy agreement before they sign.
```

### `run_free_check`

- The name "run_free_check" says "run": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Runs the free RenterCheck on one home to rent in England, as on rentercheck.co.uk: energy certificate, flood and planning designations, recorded crime nearby and sale history. Returns the findings, a link to the free report, and a link to Complete RenterCheck for the same home (rent comparison, owner, costs, deposit limits, tenancy agreement check). Give the postcode with either an address_id from find_addresses or the house number or name; if more than one home matches it returns the choices to ask about. Include the monthly rent if the renter knows it.
```

## Only reads (1)

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

### `find_addresses`

- The name "find_addresses" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Lists the homes at a postcode in England, each with an address_id for run_free_check. Pass house_number_or_name to narrow a long list. Use it when the renter has given a postcode but not which home.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `rentercheck`:
