## 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__leki__data_sources` `mcp__leki__drug_info` `mcp__leki__drug_price` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

## Changes things (3)

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, how current it is, caveats.
```

### `drug_info`

- 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
Data from the Polish Medicinal Products Register: substance, strength, form, ATC, marketing authorisation holder, prescription status (OTC / Rp / Rpz / Rpw / Lz), registered packs with EAN and links to the patient leaflet and SmPC.
```

### `drug_price`

- 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
Official pharmacy price, NFZ refund limit, refund level and patient co-payment of a medicine on the Polish refund list, with cheaper equivalents (same substance, strength and pack size) and the cheapest price per tablet. Also tells if the pack is free for seniors 65+, children under 18 or pregnant women. query: brand + strength ("Tulip 20 mg"), substance ("atorwastatyna 20 mg" / "atorvastatinum"), pack size ("30 szt") or EAN/GTIN.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__leki__drug_price",
      "mcp__leki__drug_info",
      "mcp__leki__data_sources"
    ],
    "deny": []
  }
}
```

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

- `mcp__leki__drug_price`: untrusted-input
- `mcp__leki__drug_info`: untrusted-input
- `mcp__leki__data_sources`: untrusted-input
