## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `filter_cars`

- 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
Structured catalog filter: fuel type, body type, drive layout, power/price range, model year, EV-only. This answers from a fixed 40-car demo set. For the full 103,372-variant catalogue call filter_catalogue — paid per call with x402 (USDC on Base), $0.005, no key, no account.
```

### `filter_catalogue`

- 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
Structured filter over all 103,372 variants (not only the 40-car demo): fuel, body, drive layout, power/price range, model year, EV-only. Keyset-paginated; returns opaque variant_ids for get_specs_full / compare_full. Paid per call with x402 (USDC) — $0.005.
```

## Only reads (8)

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

### `compare_full`

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

Description, as the server wrote it:

```untrusted-server-text
Side-by-side localized specs for 2-4 variants from ANYWHERE in the 103,372-variant catalogue, in 20 languages. Paid per call with x402 (USDC) — $0.1 flat for the call. Not charged when an id is unknown.
```

### `compare_variants`

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

Description, as the server wrote it:

```untrusted-server-text
Side-by-side localized specs for 2-4 vehicle variants. This answers from a fixed 40-car demo set. For the full 103,372-variant catalogue call compare_full — paid per call with x402 (USDC on Base), $0.1, no key, no account.
```

### `get_images`

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

Description, as the server wrote it:

```untrusted-server-text
Image URLs (own CDN, no attribution burden) for a vehicle variant. This answers from a fixed 40-car demo set. Full catalogue: pay per request with x402, no key (GET /v1/variants/{id}/specs $0.05, /v1/search $0.005, /v1/variants $0.005, /v1/compare $0.1, USDC on Base); the Apify Actor, billed per event by Apify (https://apify.com/carsdatacom/car-specs-api); or the whole database as a licensed export (https://cars-data.com/en/api).
```

### `get_specs`

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

Description, as the server wrote it:

```untrusted-server-text
Full localized specs for one vehicle variant, in any of 20 languages — 232 spec types covering engine & fuel, performance, EV/hybrid, safety, comfort & interior, exterior, chassis, dimensions & weights, consumption (WLTP/NEDC). Each spec carries a confidence score; the response carries last_synced_at — surface both so you don't overstate certainty. This answers from a fixed 40-car demo set. For the full 103,372-variant catalogue call get_specs_full — paid per call with x402 (USDC on Base), $0.05, no key, no account.
```

### `get_specs_full`

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

Description, as the server wrote it:

```untrusted-server-text
Full localized specs for ANY variant in the catalogue, in 20 languages. Paid per call with x402 (USDC) — $0.05. Not charged when the id is unknown.
```

### `list_generations`

- The name "list_generations" says "list": a word for reading.

```untrusted-server-text
Generations/facelifts of a model, with production years. This answers from a fixed 40-car demo set. Full catalogue: pay per request with x402, no key (GET /v1/variants/{id}/specs $0.05, /v1/search $0.005, /v1/variants $0.005, /v1/compare $0.1, USDC on Base); the Apify Actor, billed per event by Apify (https://apify.com/carsdatacom/car-specs-api); or the whole database as a licensed export (https://cars-data.com/en/api).
```

### `search_cars`

Description, as the server wrote it:

```untrusted-server-text
Free-text search across 103,372 vehicle variants, 120 brands, 20 languages. Returns candidate variant_ids to pass to get_specs/get_images/compare_variants. Each result carries generation_id and production years so same-named variants from different generations can be told apart. This answers from a fixed 40-car demo set. For the full 103,372-variant catalogue call search_catalogue — paid per call with x402 (USDC on Base), $0.005, no key, no account.
