## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input 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. | none |
| 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 (3)

Creates or changes something that can be changed back. Claude Code: ask.

### `calculate_shipment`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Calculates one shipment's greenhouse gas emissions (kg CO2e: well-to-wheel, tank-to-wheel, well-to-tank) following the GLEC Framework v3.2 and ISO 14083. Routes each leg's distance from its coordinates or codes. Returns the result per leg (distance and how it was found, method, data type, emission factor and its source, distance adjustment, notes on legs Carbonara added) and a step-by-step calculation sheet with the arithmetic and the GLEC page and ISO 14083 clause behind each step.
```

### `calculate_shipments`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Calculates several shipments at once, each like calculate_shipment. A failing shipment doesn't stop the others; each failure says why and whether sending it again can help. Set explain to add calculation sheets (first 25 shipments).
```

### `emissions_report`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Calculates shipments and returns a report with the basic content ISO 14083 asks for at the level of transport services (GLEC v3.2 Section 2 Ch.1): coverage and failures, totals split into TTW and WTT, intensity, per mode and hub type, energy carriers, data quality (primary/modelled/default shares, sources, models), distance adjustments, and notes. Returned as Markdown and as structured data.
```

## Only reads (3)

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

### `find_places`

- The name "find_places" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Finds cities, sea and inland ports, rail and road terminals, inland depots, border crossings and airports by name, UN/LOCODE or IATA code, with coordinates, from an embedded list (GeoNames, UN/LOCODE, OurAirports). Use it to fill a leg's from and to.
```

### `get_methodology`

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

Description, as the server wrote it:

```untrusted-server-text
Explains the whole method: scope (WTW, TTW, WTT), inputs, the four calculation methods with formulas, how distances are routed, distance adjustment factors, added road legs, the emission factor datasets and their sources and limitations, data quality, what every result field means, errors, and how to present results.
```

### `list_vehicle_types`

- The name "list_vehicle_types" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Lists the vehicle types (and their short aliases) with their emission factors: g CO2e per tonne-km tank-to-wheel and well-to-tank, the distance type they are per, source and year, and for trucks the load model's payload (what load_factor 1 means). Optionally the fuels for the fuel method.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__carbonara__find_places",
      "mcp__carbonara__list_vehicle_types",
      "mcp__carbonara__get_methodology"
    ],
    "ask": [
      "mcp__carbonara__calculate_shipment",
      "mcp__carbonara__calculate_shipments",
      "mcp__carbonara__emissions_report"
    ],
    "deny": []
  }
}
```

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:02:06.901Z, unchanged since 2026-10-22T15:02:06.901Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `3` |

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 3 tools that change things (3 write). Whether a call also works without credentials was not tested: tools are never called.

https://carbonara-co2.org/mcp: tools/list returned 6 tools to an anonymous client, including calculate_shipment (write), calculate_shipments (write), emissions_report (write)
