## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `calculate_ring_cost`

- 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
Calculate 1–3 year hardware plus required subscription cost in the recorded currency. Not a local quote; no exchange-rate conversion, taxes or optional fees.
```

## Only reads (3)

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

### `compare_rings`

- The name "compare_rings" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read the original evidence, limitations, sizing, battery and subscription records for two to four ring IDs. Not a hands-on review or diagnosis.
```

### `find_regional_offers`

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

Description, as the server wrote it:

```untrusted-server-text
Read country-specific official and paid retailer links for one ring. Preserve affiliate URLs. Brand storefronts and model searches are not exact listings; no checkout or live inventory.
```

### `search_rings`

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

Description, as the server wrote it:

```untrusted-server-text
Search dated smart-ring records by brand/model, phone, use case and buyer country. Unknown availability is not treated as available.
```
