## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `ipinfo_check_privacy`

- 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
Check whether IP addresses are using privacy or anonymity services.

Returns privacy flags for each IP: whether it is anonymous, using a VPN, proxy,
relay, or Tor, and whether it is an anycast, hosting, mobile, or satellite address.

Requires a paid API token. Results are paginated.

If the API reports an error for specific IPs, those IPs are listed in errors
with the reason and left out of results. Do not treat a missing result as
"no privacy services detected": check errors.

Results are cached in memory for the session, so repeat checks of the same IP
are served from cache without consuming API quota. You do not need to maintain
your own cache or deduplicate IPs before calling this tool. The _meta field
reports api_calls_made and from_cache counts.
```

### `ipinfo_check_residential_proxy`

- 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
Check whether IP addresses are known residential proxies.

Returns whether each IP is a residential proxy and, if so, the proxy service name,
the date it was last seen, and the percentage of days the IP was observed as a proxy.

Requires a paid API token with residential proxy access. Results are paginated.

If the API reports an error for specific IPs, those IPs are listed in errors
with the reason and left out of results. Do not treat a missing result as
"not a residential proxy": check errors.

Results are cached in memory for the session, so repeat checks of the same IP
are served from cache without consuming API quota. You do not need to maintain
your own cache or deduplicate IPs before calling this tool. The _meta field
reports api_calls_made and from_cache counts.
```

### `ipinfo_quota`

- 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
Check your IPinfo API usage and remaining quota.

Returns daily and monthly request counts, the plan limit,
and how many requests remain.
```

## Only reads (3)

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

### `ipinfo_asn`

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

Description, as the server wrote it:

```untrusted-server-text
Get autonomous system (network ownership) information for IP addresses.

By default queries the IPinfo Lite endpoint, which returns ASN, name, and domain.
Set detailed=True to query the full lookup endpoint, which also includes the network type
(e.g. isp, hosting, business, education).

Results are paginated.

If the API reports an error for specific IPs, those IPs are listed in errors
with the reason and left out of results.

Results are cached in memory for the session, so repeat lookups of the same IP
are served from cache without consuming API quota. You do not need to maintain
your own cache or deduplicate IPs before calling this tool. The _meta field
reports api_calls_made and from_cache counts.
```

### `ipinfo_geolocate`

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

Description, as the server wrote it:

```untrusted-server-text
Get geographic location data for one or more IP addresses.

By default queries the IPinfo Lite endpoint, which returns country and continent.
Set detailed=True to query the full lookup endpoint, which adds city, region,
coordinates, timezone, and postal code.

Results are paginated.

If the API reports an error for specific IPs, those IPs are listed in errors
with the reason and left out of results.

Results are cached in memory for the session, so repeat lookups of the same IP
are served from cache without consuming API quota. You do not need to maintain
your own cache or deduplicate IPs before calling this tool. The _meta field
reports api_calls_made and from_cache counts.
```

### `ipinfo_lookup`

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

Description, as the server wrote it:

```untrusted-server-text
Look up geolocation, network, and metadata for one or more IP addresses.

By default queries the IPinfo Lite endpoint, which returns country, continent, and ASN info.
Set detailed=True to query the full lookup endpoint, which adds city-level geolocation,
privacy flags (VPN, proxy, Tor, hosting, anycast), and richer AS data.

Results are paginated. Use page and page_size to control which slice is returned.

If the API reports an error for specific IPs, those IPs are listed in errors
with the reason and left out of results.

Results are cached in memory for the session, so repeat lookups of the same IP
are served from cache without consuming API quota. You do not need to maintain
your own cache or deduplicate IPs before calling this tool. The _meta field
reports api_calls_made and from_cache counts.
```
