## Findings

- **warn** Annotations that disagree with the tool in `buy_full_vehicle_report` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "buy_full_vehicle_report" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":true}; The description's first verb is "return": a word for reading.
```


## Changes things (5)

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

### `buy_full_vehicle_report`

- The description's first verb is "return": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Returns a secure payment link (iDEAL or card, via Dodo Payments, EUR 1.95 incl. VAT) for the full English vehicle report: APK inspection history with defects, recall details, import/taxi/export history, specs and catalogue price. Only use when the user wants the full report or asks to buy it.
```

### `nl_apk_alert`

- 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
Use when the user asks when a Dutch car's APK (MOT) expires or whether it is still valid: expiry date, days left and a status band (expired, due within 30 or 90 days, ok), with insurance and open-recall flags. Cheap enough to run daily for a fleet. Input: Dutch licence plate. Source: RDW. Costs 0.001 USDC via x402, or 1 credit of a Factline API key.
```

### `nl_car_model`

- 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. Use when the user asks how reliable a car model is, or which used car to buy: facts for the model in the Netherlands from RDW data: APK (MOT) defect rate vs the average of all models, the 10 most common APK defects, recalls with component and risk, share with an open recall, share with an illogical (rolled-back) odometer, cars registered. Covers ~450 common passenger-car models.
```

### `nl_vehicle_basic`

- 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. Use when the user gives a Dutch licence plate or asks about a specific car in the Netherlands: make, model, age, fuel, Euro class, APK (MOT) expiry, insurance, open recall, RDW odometer verdict and a risk level. Source: RDW.
```

### `nl_vehicle_report`

- 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
Use when the user asks about a specific Dutch car or licence plate, for example before buying it used: make, model, APK expiry and full inspection history with defects, insurance, open recalls, RDW odometer verdict, import/taxi/export history, specs, CO2, catalogue price and risk flags, in English. Input: Dutch licence plate. Source: RDW. Costs 0.02 USDC via x402, or 10 credits of a Factline API key.
```

## Only reads (1)

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

### `nl_vehicle_compare`

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

Description, as the server wrote it:

```untrusted-server-text
Use when the user is choosing between 2 or 3 Dutch used cars: plates side by side with make, model, age, APK expiry, insurance, open recall, odometer verdict, import and taxi history, catalogue price, CO2 and power, the best per metric and red flags. Input: Dutch licence plates. Source: RDW. Costs 0.004 USDC via x402, or 2 credits of a Factline API key.
```
