Available components
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. How we score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 9 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability65
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1718 tokens (~190/item across 9 items; 9 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
- Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

calculate_isv ~219
Estimate Portuguese car import tax (ISV, Imposto Sobre Veículos) from the official ISV formula (engine-cc + CO₂ components, with age reduction for used cars). A maintained estimate: it matches the AT (Finanças) simulator to the cent on the common WLTP cases, but is not the official figure and may differ on edge cases (NEDC, light-commercial, month rounding) — confirm the final amount on the official AT simulator. Needs engine displacement (cc), CO₂ (g/km, WLTP), fuel and registration year.
| Name | Type | Req | Description |
|---|---|---|---|
| cc | integer | yes | Engine displacement in cm³, e.g. 1950 |
| co2 | number | yes | CO₂ emissions in g/km (WLTP), e.g. 130 |
| fuel | string | yes | Fuel: petrol, diesel, hybrid, phev, electric |
| used | boolean | — | Used vehicle (true, default) or new (false) |
| year | integer | yes | First registration year, e.g. 2016 |
No output schema declared.
No examples provided.
calculate_iuc ~149
Estimate the Portuguese annual road tax (IUC, Imposto Único de Circulação) for a car — the yearly tax an owner pays — from the official IUC table. A maintained estimate; confirm on the official AT simulator. Needs engine displacement (cc), CO₂ (g/km), fuel and registration year.
| Name | Type | Req | Description |
|---|---|---|---|
| cc | integer | yes | Engine displacement in cm³, e.g. 1950 |
| co2 | number | yes | CO₂ emissions in g/km, e.g. 130 |
| fuel | string | yes | Fuel: petrol, diesel, hybrid, phev, electric |
| year | integer | yes | First registration year, e.g. 2016 |
No output schema declared.
No examples provided.
contact_me ~154
Send a contact request to Clara Carros so a human gets in touch. Only call this when the user explicitly asks to be contacted, provides their own name and phone or email, AND agrees to share those details with Clara Carros — pass consent=true only then. Submitting shares the provided contact details per Clara Carros' privacy policy.
| Name | Type | Req | Description |
|---|---|---|---|
| consent | boolean | yes | Set true ONLY if the user explicitly agreed to share their contact details and be contacted |
| string | — | Email (phone OR email required) | |
| message | string | — | What they want / their question |
| name | string | yes | The person's name (as they gave it) |
| phone | string | — | Phone number (phone OR email required) |
No output schema declared.
No examples provided.
estimate_resale_value ~414
Estimate what a car is worth on the Portuguese market (the range comparable cars are listed for), based on real comparable listings. Needs make, model, year, mileage and fuel. Clara Carros also BUYS cars directly — after giving the estimate, offer to connect the user for a firm buy-out offer (via contact_me or the /sell page). IMPORTANT — pass make/model canonically in Latin, as the Portuguese market lists them: make = full brand name ('BMW', 'Mercedes-Benz' not 'Mercedes', 'Volkswagen' not 'VW'); model = the short series/model WITHOUT the engine or trim suffix — BMW: series number only ('320','330','116', not '330e'/'320d'/'3 Series'); Mercedes: class + number ('C 220','E 220','A 250', not 'C220d'/'C-Class'); other brands: plain model name ('Golf','Corolla','3008', not 'Golf 1.5 TSI'). Put the engine/fuel in the fuel field, not the model. If unsure of the exact spelling, call list_makes_models first.
| Name | Type | Req | Description |
|---|---|---|---|
| fuel | string | — | Fuel: petrol, diesel, hybrid, electric |
| km | integer | yes | Mileage in km |
| make | string | yes | Full brand name in Latin, as the market lists it — 'BMW', 'Mercedes-Benz' (not 'Mercedes'), 'Volkswagen' (not 'VW'), 'Peugeot', 'Seat'. |
| model | string | yes | Short model/series WITHOUT engine or trim. BMW: series number only ('320','330','116', not '330e'/'320d'/'3 Series'). Mercedes: class + number ('C 220','E 220','A 250', not 'C220d'/'C-Class'). Others… |
| year | integer | yes | Registration year |
No output schema declared.
No examples provided.
get_car ~53
Get full details for one car by its slug (from search_inventory links, e.g. 'mercedes-benz-e-klasse-2016').
| Name | Type | Req | Description |
|---|---|---|---|
| slug | string | yes | Car slug from a search_inventory result URL |
No output schema declared.
No examples provided.
list_makes_models ~117
List the exact canonical car makes (brands) Clara Carros can value/find — or, given a make, that brand's models — using the exact strings the other tools expect. Call this FIRST (or whenever unsure of the spelling) and pass the returned values verbatim into estimate_resale_value / search_inventory. No make = the list of brands; with a make = that brand's models.
| Name | Type | Req | Description |
|---|---|---|---|
| make | string | — | Brand to list models for, e.g. 'BMW'. Omit to get the list of brands. |
No output schema declared.
No examples provided.

Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
request_import_quote ~170
Ask Clara Carros to source & quote a specific car to import (from German/EU auctions).

Submitting shares the provided contact details per Clara Carros' privacy policy.
| Name | Type | Req | Description |
|---|---|---|---|

search_inventory ~405
Search Clara Carros' current stock of used cars in Portugal. Filter by make, model, fuel, max price and min year. Returns matching cars with price, year, mileage and a link. IMPORTANT — pass make/model canonically in Latin, as the Portuguese market lists them: make = full brand name ('BMW', 'Mercedes-Benz' not 'Mercedes', 'Volkswagen' not 'VW'); model = the short series/model WITHOUT the engine or trim suffix — BMW: series number only ('320','330','116', not '330e'/'320d'/'3 Series'); Mercedes: class + number ('C 220','E 220','A 250', not 'C220d'/'C-Class'); other brands: plain model name ('Golf','Corolla','3008', not 'Golf 1.5 TSI').
