## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-23.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not yet verified: we couldn't confirm whether this endpoint requires it.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 0/100
  - Transport check failed: declared streamable-http, but the endpoint redirected instead of responding directly.
- **Schema Quality & AI Usability**: 0/100
  - Schema not yet verified: we couldn't read the endpoint's schema, or could read only part of its tool list.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).

## MCP tools (6)

### `calculate_shipment` (~335 tokens)

Calculate a shipment's emissions

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.

Input parameters:

- `add_road_legs` (boolean): Add road legs where the legs don't join up (gaps over 5 km), and to a port or terminal when a sea, rail or river leg starts or ends off its network (default true). Added legs are marked in the result.
- `container_load` (string): With teu: a container load profile defined by the dataset, instead of teu_net_tonnes
- `hubs` (array): Hub stops (transhipment, storage); needs a dataset with hub factors.
- `id` (string): Your reference for the shipment
- `legs` (array, required): The legs in order, from where the shipper hands the goods over to where the consignee receives them.
- `teu` (number): Containers in TEU, instead of weight_kg; needs teu_net_tonnes
- `teu_net_tonnes` (number): With teu: net cargo tonnes per TEU (container tare is not added)
- `weight_kg` (number): Cargo weight in kg (or give teu instead)

### `calculate_shipments` (~168 tokens)

Calculate many shipments

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).

Input parameters:

- `add_road_legs` (boolean): Add road legs where the legs don't join up (gaps over 5 km), and to a port or terminal when a sea, rail or river leg starts or ends off its network (default true). Added legs are marked in the result.
- `explain` (boolean): Add the step-by-step calculation sheet of each shipment (up to 25)
- `shipments` (array, required): The shipments. Without an API key the public service takes up to 100 per call; with one, up to 10,000.

### `emissions_report` (~289 tokens)

Emissions report over many shipments

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.

Input parameters:

- `add_road_legs` (boolean): Add road legs where the legs don't join up (gaps over 5 km), and to a port or terminal when a sea, rail or river leg starts or ends off its network (default true). Added legs are marked in the result.
- `declare_iso` (boolean): Add the ISO 14083:2023 conformity statement. Only when the user explicitly confirms that their data collection and boundaries conform.
- `organisation` (string): Organisation the report is for
- `period_from` (string): Start of the period covered, YYYY-MM-DD
- `period_to` (string): End of the period covered, YYYY-MM-DD
- `reference` (string): Where supporting information can be found
- `shipments` (array, required): The shipments. Without an API key the public service takes up to 100 per call; with one, up to 10,000.
- `title` (string): Report title

### `find_places` (~174 tokens)

Find places

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.

Input parameters:

- `kinds` (array): Only places of these kinds: port (sea or inland port), rail and road (terminals), airport, inland (inland clearance depot), border (crossing), city. E.g. ["port"] for a sea or river leg, ["airport"]…
- `limit` (integer): Most results (default 10)
- `query` (string, required): Place name, UN/LOCODE (NLRTM) or IATA code (CPH)

### `list_vehicle_types` (~129 tokens)

List vehicle types and emission factors

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.

Input parameters:

- `include_fuels` (boolean): Also list fuels and their factors
- `mode` (string)
- `search` (string): Only vehicle types whose id, alias or source contains this, e.g. "container" or "refrigerated"

### `get_methodology` (~75 tokens)

How Carbonara calculates

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.

## Common questions

### What is the Carbonara freight CO2e MCP server?

Carbonara freight CO2e is an MCP server listed in the public MCP registry as io.github.majidkabir/carbonara. Freight CO2e by road, rail, sea, inland waterway and air (GLEC, ISO 14083), every step shown. This page covers its hosted endpoint (https://carbonara-co2.org/mcp).

### Is the Carbonara freight CO2e MCP server safe to use?

Carbonara freight CO2e scores 23 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Carbonara freight CO2e MCP server expose?

Carbonara freight CO2e exposes 6 tools: calculate_shipment, calculate_shipments, emissions_report, find_places, list_vehicle_types, get_methodology. Their descriptions and schemas cost roughly 1,170 tokens of context every time the server is loaded.

### Does the Carbonara freight CO2e MCP server require authentication?

Its publisher declares no required credentials for Carbonara freight CO2e. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.

### Is the Carbonara freight CO2e MCP server still maintained?

Carbonara freight CO2e is still listed as active in the MCP registry. We last reached this channel on 23 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
