## Findings

No check matched anything in these tool definitions.


## Only reads (6)

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

### `headers`

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

Description, as the server wrote it:

```untrusted-server-text
Return all HTTP request headers as seen by the IP.LS server (including X-Real-IP / X-Forwarded-For injected by the frontend proxy). Useful for debugging proxies and client identity.
```

### `ip_lookup`

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

Description, as the server wrote it:

```untrusted-server-text
Look up geolocation, ISP and network info for any IPv4/IPv6 address or hostname, or an array of them for batch lookup. Returns ip, city, region, country, coordinates, ASN/ISP, timezone and continent (full name, e.g. North America); when a domain is queried, an extra `domain` field echoes it. Data source: DB-IP Lite (CC BY 4.0). Anycast IPs are approximate.
```

### `ip_resolved`

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

Description, as the server wrote it:

```untrusted-server-text
Resolve a domain to all its A and AAAA records (deduplicated, up to 6) and return geolocation for each address. Returns an array of { ip, protocol, domain, city, region, country, coordinates, ASN/ISP, ... }. For a bare IP, returns a single-element array.
```

### `ip_self`

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

Description, as the server wrote it:

```untrusted-server-text
Get geolocation and network info about the caller's own public IP, plus the protocol stack (IPv4/IPv6) of the current connection. On dual-stack machines the stack is chosen by the client and may differ from `curl ip.ls`, which picks a random stack; use curl -4/-6 locally to get the other stack, or — for clients that cannot pick a stack (browser, PowerShell, most HTTP libraries) — the single-stack hostnames https://4.ip.ls / https://6.ip.ls (DNS selects the stack; an unreachable 6.ip.ls means no usable IPv6). Data comes from a server-side GeoIP lookup on the caller's real IP.
```

### `ip_summary`

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

Description, as the server wrote it:

```untrusted-server-text
Summarize a large batch of IPs into distributions by country, continent, ASN/operator and network prefix, each bucket with a sample of addresses. Use instead of ip_lookup once the input is in the hundreds or thousands — ip_lookup returns every row, which no context window holds. Up to 5000 addresses or 100 hostnames. Counts are per occurrence; nothing is dropped silently (failed → `errors`, no database record → `no_data`, unlisted buckets → `tail`), the same input set always returns the same numbers, and the result is facts only — no datacenter/residential classification, no verdict. DB-IP Lite (CC BY 4.0).
```

### `ua`

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

Description, as the server wrote it:

```untrusted-server-text
Return the User-Agent string of the current HTTP client.
```
