## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input.

| 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. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__othermile__border_lane_insights` `mcp__othermile__border_quote` `mcp__othermile__door_cost_estimate` |

## Findings

- **warn** Annotations that disagree with the tool in `door_cost_estimate` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "door_cost_estimate" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"openWorldHint":false}; The input addresses people (input.to): what it sends cannot be taken back.
```

- **warn** Annotations that disagree with the tool in `border_quote` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "border_quote" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"openWorldHint":false}; The input addresses people (input.to): what it sends cannot be taken back.
```

- **warn** Annotations that disagree with the tool in `border_lane_insights` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "border_lane_insights" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true}; The input addresses people (input.to): what it sends cannot be taken back.
```


## Can't be undone (3)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `border_lane_insights`

- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
What shoppers and sellers actually paid and how long parcels actually took on a route, from real reports. Only shown when enough reports exist.
```

### `border_quote`

- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Estimate duties, tariffs, taxes and fees for goods moving into Canada or the US, by parcel or freight (truck, rail, air, ocean), and whether any item is banned. Gives who pays under the Incoterm, and what the exporting country requires. Use before buying from or shipping across the border.
```

### `door_cost_estimate`

- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Estimate what a shopper may pay at the door for one parcel shipped between Canada and the United States: duty, tariffs and surtaxes, sales tax and carrier or postal fees, with the official rules in force today. Describe the product in plain words; a tariff code is suggested from it. Use for questions like "what will I pay on a hoodie from a US store shipped to Ontario?"
```

## Only reads (1)

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

### `border_rules_status`

- The name "border_rules_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Which Canada and US border rules are in force right now: tariff measures, rates, start dates and whether each list has been checked against the official text.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__othermile__border_rules_status"
    ],
    "ask": [
      "mcp__othermile__door_cost_estimate",
      "mcp__othermile__border_quote",
      "mcp__othermile__border_lane_insights"
    ],
    "deny": []
  }
}
```

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

- `mcp__othermile__door_cost_estimate`: outbound
- `mcp__othermile__border_quote`: outbound
- `mcp__othermile__border_lane_insights`: outbound
