## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `analyze_listing`

- The name "analyze_listing" says "analyze": a word for reading.
- The description's first verb is "start": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Start a BuyerAware pre-purchase verdict on ONE used vehicle. Runs a mechanic-grade read: ranked failure points with $ exposure, recalls, seller-claim fact-check, fair price range, adjusted true cost, risk score 1-10, BUY / BUY_WITH_CONDITIONS / WALK_AWAY, a word-for-word negotiation script, and lower-risk 'Tank' alternatives. Supply whichever of listing_url, listing_text or vin you have — at least one is required, and more context sharpens the verdict. Takes ~1-2 minutes: returns a job_id, then poll get_verdict. Costs 1 credit. For 'what should I buy instead' use tank_alternatives, which is free.
```

### `create_trial_key`

- The name "create_trial_key" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create a BuyerAware API key so this user can run verdicts (3 free). Call this once when no key is configured, then show the user the key and tell them to save it. Do not call it again for someone who already has a key — one trial per email address.
```

### `tank_alternatives`

- 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
FREE, no API key needed, answers instantly. Recommend 2-3 lower-risk used vehicles ('Tanks') from BuyerAware's curated 47-platform database that land near a budget. Use when a buyer asks what to buy instead, or what is reliable for $X. Use analyze_listing instead when they have a specific car in mind.
```

## Only reads (2)

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

### `get_verdict`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch the result of an analyze_listing job. If status is 'queued' or 'running', wait ~15 seconds and call again. Free — polling never costs a credit.
```

### `tank_lookup`

- The name "tank_lookup" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
FREE, no API key needed, answers instantly. Look up one platform in BuyerAware's curated database: risk score, verdict, the one known trap, private-party value at a mileage, 5-year operating cost. Covers 47 US-market platforms; anything outside it returns no match, which is itself a signal — follow up with analyze_listing.
```
