## Findings

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

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

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":true}; The name "phone_lookup" says "lookup": a word for reading.
```

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

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

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":true}; The name "ip_lookup" says "lookup": a word for reading.
```

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

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

## Changes things (4)

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

### `dns_check`

- The description's first verb is "inspect": 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
Inspect a user-provided domain's MX, SPF, DMARC or DKIM record and report issues. Does not change DNS. DKIM requires a selector. Uses 1 existing account credit for a successful check.
```

### `email_verify`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Check an email address supplied by the user for syntax, MX records, disposable-domain and role-address indicators. Does not prove mailbox ownership or guarantee delivery. Uses 1 existing account credit for a successful check; does not send email.
```

### `ip_lookup`

- The name "ip_lookup" says "lookup": 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
Look up approximate IP location and network/provider indicators for an IP address supplied by the user. IP location is not a person's precise location or identity; privacy flags may be unavailable. Uses 1 existing account credit for a successful check.
```

### `phone_lookup`

- The name "phone_lookup" says "lookup": 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
Check a user-provided phone number for carrier and line type. Optional US/CA caller-name data is a carrier listing, not identity verification. Uses existing account credits: 1 for landline/VoIP/toll-free, 3 for mobile or unknown; caller name adds 2. Reserves up to 5 credits before execution. Does not place calls or send messages.
```
