## Quality 81/100 (new)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 86 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 6 of 6 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: emissions_report (destructiveHint); find_places (destructiveHint); list_vehicle_types (destructiveHint); …
- pass `tools.token_cost`: about 5,360 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool history recorded for 1 of the 7 days needed

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 6, about 5,360 tokens to load them all
- tool set hash: 61e25a1a5162148592dc0f9a18964275
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.majidkabir/carbonara.svg)](https://protogrid.dev/servers/io.github.majidkabir/carbonara)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (6)

- `calculate_shipment`: 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`: 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`: 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.
- `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.
- `get_methodology`: 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`: 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.
