## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data 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. | `mcp__jp-foreign-patient-hospitals__foreign_patient_hospital_changes` `mcp__jp-foreign-patient-hospitals__foreign_patient_hospital_lookup` |
| 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 (1)

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

### `foreign_patient_hospital_changes`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Which medical institutions were added to, changed in, removed from or returned to MHLW's list of medical institutions accepting foreign patients since a date (this service's own record of list versions; MHLW keeps none)? Optional prefecture and change_type filters. Free window: last 30 days. A public-service listing, not an enforcement list: removals are dated, and no reason is inferred.
```

## Only reads (3)

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

### `catalog`

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

Description, as the server wrote it:

```untrusted-server-text
List the tools of this server with prices, data sources, licensing, daily limits and data freshness.
```

### `foreign_patient_hospital_lookup`

- The name "foreign_patient_hospital_lookup" says "lookup": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Which medical institutions does MHLW list as accepting foreign patients in this prefecture or city, with which languages and categories? Give prefecture (or the name as published); city, language (EN, ZH...), category and facility_type narrow. Returns listed, no_longer_listed_since, not_found_in_checked_records or unknown, institutions with address and phone as published, and source. Not medical advice; call before visiting; emergency 119.
```

### `get_receipt`

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

Description, as the server wrote it:

```untrusted-server-text
Re-fetch the stored result of a settled paid call by its receipt_id, for when the response was lost after payment. Free. Unknown or unsettled receipt ids return RECEIPT_NOT_FOUND. Results are kept for 90 days after settlement.
```
