## Findings

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

```untrusted-server-text
The server marks "benefits_examples" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

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


## Changes things (3)

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

### `benefits_api_docs`

- 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 you need field definitions, ordering guarantees or the error format before calling another tool.
```

### `benefits_examples`

- The description's first verb is "copy": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Use to copy a working example call instead of guessing tool arguments.
```

### `expiring_soon`

- 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 timing matters — a user asking what is about to end, or whether to act now. Offers with no stated end date are never included here.
```

## Only reads (3)

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

### `compare_bonuses`

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

Description, as the server wrote it:

```untrusted-server-text
Use when a user is choosing between specific offers. Returns each offer's key fields plus a summary naming the highest bonus and the earliest expiry.
```

### `get_bonus`

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

Description, as the server wrote it:

```untrusted-server-text
Use before recommending an offer, to read its exact requirements, minimum deposit, direct-deposit rules, expiry date, state availability and the date its terms were last verified. Quote the requirements rather than paraphrasing money amounts.
```

### `search_bonuses`

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

Description, as the server wrote it:

```untrusted-server-text
Use when a user wants to find a US bank account, savings, credit card or brokerage signup bonus, or asks which offers are worth opening. Returns matching offers sorted by bonus value, highest first — except when balance_transfer is true, which sorts by intro window instead.
```
