## 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__szkoly__data_sources` `mcp__szkoly__find_schools` `mcp__szkoly__school_details` |
| 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 (2)

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.
```

### `school_details`

- 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
One school: register data (type, address, governing body, pupils, teachers, pupils per teacher) and exam results for the last years by subject – eighth-grade exam or matura (pass rate, basic and extended subjects) – compared with the county and national averages. school: RSPO number or name; town helps to disambiguate.
```

## Only reads (1)

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

### `find_schools`

- The name "find_schools" says "find": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "website": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Schools or kindergartens in a Polish town / gmina or near an address: type, public or non-public, address, number of pupils, RSPO id, website and the latest exam results (eighth-grade exam for primary schools, matura pass rate and averages for licea/technika) vs the national average. place: town "Kórnik", gmina, address "Kraków, Długa 5" (sorted by distance) or 'lat,lon'.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `szkoly`:

```json
{
  "permissions": {
    "allow": [
      "mcp__szkoly__find_schools"
    ],
    "ask": [
      "mcp__szkoly__school_details",
      "mcp__szkoly__data_sources"
    ],
    "deny": []
  }
}
```

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

- `mcp__szkoly__find_schools`: untrusted-input
- `mcp__szkoly__school_details`: untrusted-input
- `mcp__szkoly__data_sources`: untrusted-input
