## 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__kolejki-nfz__data_sources` `mcp__kolejki-nfz__find_benefits` `mcp__kolejki-nfz__find_care` |
| 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.

### `data_sources`

- 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
Where the data comes from and caveats.
```

## Only reads (2)

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

### `find_benefits`

- The name "find_benefits" says "find": 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
Look up official NFZ benefit names (clinics, wards, tests, procedures) matching a word, e.g. 'rezonans' or 'okulist'. Use the exact name as find_care.benefit.
```

### `find_care`

- The name "find_care" says "find": 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
Where a specialist, diagnostic test or treatment paid by NFZ is available soonest near a place in Poland. Returns clinics and hospitals with NFZ's forecast waiting time, people in the queue, address, phone, distance, accessibility and whether children are seen. service: everyday words (okulista, kardiolog, rezonans, zaćma, rehabilitacja…) or an exact NFZ benefit name from find_benefits. place: town, address or 'lat,lon'.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `kolejki-nfz`:

```json
{
  "permissions": {
    "allow": [
      "mcp__kolejki-nfz__find_care",
      "mcp__kolejki-nfz__find_benefits"
    ],
    "ask": [
      "mcp__kolejki-nfz__data_sources"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__kolejki-nfz__find_care`: untrusted-input
- `mcp__kolejki-nfz__find_benefits`: untrusted-input
- `mcp__kolejki-nfz__data_sources`: untrusted-input
