## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (7)

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

### `answer`

- 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
Give a place name in Japanese or English (e.g. 帯広, Obihiro, 京都市 の基準局, 札幌の警報). Returns in one call: the municipality (5-digit code), JMA warnings in force, the nearest free RTK base station (km, mountpoint, host) and the page URLs. No key. Use this first when a user asks about a Japanese place; call here/rtk_bases_near for detail.
```

### `gnss_in_japan`

- 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
Index of the English field guide for engineers using GNSS in Japan: QZSS status, CLAS, MADOCA-PPP, GEONET and community bases, coordinates and heights (JGD2011/JGD2024), bringing equipment and radio law. Returns titles, one-line summaries and URLs.
```

### `here`

- 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
For one point in Japan: municipality and its 5-digit code, JMA warnings and advisories in force (with English names), nearest AMeDAS observation, heat (WBGT), earthquakes within 300 km, hazard zones (flood, tsunami, storm surge, landslide), elevation, nearest free RTK base, furusato-nozei prices for the municipality and the cost of living of the matching surveyed city (rent, utilities, staples; Statistics Bureau monthly survey) from kurashigram.com. Same as GET https://kuongeo.com/api/here. Warnings are relayed from JMA, not issued here.
```

### `kurashigram_prices`

- The input takes a statement or command to run (input.code), which can change anything it can reach.

Description, as the server wrote it:

```untrusted-server-text
Furusato-nozei return goods listed by a Japanese municipality on Rakuten, normalised to grams per 10,000 yen of donation, from kurashigram.com (CC BY 4.0). Keyed by the same 5-digit municipality code.
```

### `next_departures`

- 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
For travellers in Japan. Give a place or sight in Japanese or English (e.g. Miyajima, 宮島, Naoshima ferry, Shirakawa-go bus, Churaumi, Aso crater, Kumamoto Station, Toyama Station tram, Ise Jingu, Naha Airport). Returns in one call: the next boat (time, minutes to go, operator, last boat today) and the next bus/tram/monorail (time, minutes, route, destination, stop number, live or timetable), the page URL and the JSON URL. Covers Hiroshima, Kumamoto, Okayama/Uno Port, Toyama/Shirakawa-go, Ise/Toba and Okinawa (26 places, 2026-09). Live positions only where operators publish them; boats are timetables. No key.
```

### `place`

- The input takes a statement or command to run (input.code), which can change anything it can reach.

Description, as the server wrote it:

```untrusted-server-text
Static facts for a municipality of Japan by 5-digit code (JIS X 0402): names (ja/en), prefecture, population (2020 census), JMA warning area and region, centre point, and the URL of its page on kuongeo.com. Use the here tool with the centre point for live values.
```

### `rtk_bases_near`

- 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
Nearest online community RTK base stations (NTRIP) to a point, worldwide, from KUON GEO's 10-minute polling. Returns mountpoint, host, distance in km and a baseline grade.
```

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 7 tools that change things (7 write). Whether a call also works without credentials was not tested: tools are never called.

https://kuongeo.com/mcp: tools/list returned 7 tools to an anonymous client, including next_departures (write), answer (write), here (write), place (write), rtk_bases_near (write) and 2 more
