## 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__mot__lookup_plate` |
| 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.


## Only reads (4)

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

### `get_make_reliability`

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

Description, as the server wrote it:

```untrusted-server-text
A make's MOT reliability grade over all its cars, and every graded model of that make ranked by the share of UK cars it beats once age and mileage are taken into account.
```

### `get_model_reliability`

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

Description, as the server wrote it:

```untrusted-server-text
A model's MOT reliability over all years: grade, first-time pass rate, points above or below a typical car of the same age and mileage, and the share of UK cars it beats. Give year, fuel and/or engine to also get those versions, each with its own grade and the areas where it fails more often than similar cars (weak spots).
```

### `lookup_plate`

- The name "lookup_plate" 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
One UK car's MOT history from the DVSA by its registration: each test with its result, mileage and defects or advisories, whether its MOT is valid, warnings (mileage going down, gaps with no MOT, an outstanding safety recall) and its model's reliability grade.
```

### `search_cars`

- The name "search_cars" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find UK car makes and models by name, e.g. "Fiesta", "Toyota Yaris" or "Kia". Returns up to 10 matches with their MOT reliability grade, first-time pass rate and the share of UK cars they beat, for get_model_reliability or get_make_reliability.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__mot__search_cars",
      "mcp__mot__get_make_reliability",
      "mcp__mot__get_model_reliability",
      "mcp__mot__lookup_plate"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__mot__lookup_plate`: untrusted-input
