## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false}; The name "generateUUID" says "generate": a word for a change.
```


## Changes things (2)

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

### `generateUUID`

- The name "generateUUID" says "generate": 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
Generates a UUID v4 identifier for transactions, session keys, or unique names.
```

### `memoryStore`

- The name "memoryStore" says "store": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Stores a key-value fact in persistent memory across sessions.
```

## Only reads (5)

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

### `extractTextFromUrl`

- The description's first verb is "fetch": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetches a URL and returns clean readable text with boilerplate removed.
```

### `getDomainIntel`

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

Description, as the server wrote it:

```untrusted-server-text
Returns domain intelligence and WHOIS data via RDAP: registrar, creation date, expiration, nameservers, status flags.
```

### `getGasPrice`

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

Description, as the server wrote it:

```untrusted-server-text
Returns the current Ethereum gas price in gwei from Base mainnet.
```

### `getTimestamp`

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

Description, as the server wrote it:

```untrusted-server-text
Returns the current unix timestamp in milliseconds, seconds, and ISO 8601. Use for scheduling, logging, or time-based reasoning.
```

### `memoryRetrieve`

- The name "memoryRetrieve" says "retrieve": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Retrieves a previously stored memory value by key.
```
