Available components
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security98
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- 31 of 96 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency45
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 6 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability70
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1163 tokens (~193/item across 6 items; 6 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 Management87
- Stability observed for 26 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
check_fair_price ~345
Check whether a car's asking price is fair for the Portuguese market — the TransparentCars transparency check. Given make, model, year and mileage, it returns the range comparable cars actually sell for (low / typical / high), built from real listings. If you pass asking_price, it also gives a plain verdict: fair, above market, or below market — so a buyer knows before they walk in. Works for ANY car (a listing you found elsewhere, or one of ours). IMPORTANT — pass make/model canonically in Latin: make = full brand name ('Renault', 'Volkswagen' not 'VW'); model = short name WITHOUT engine/trim ('Clio' not 'Clio dCi', 'Golf' not 'Golf 1.5 TSI'). If unsure of spelling, call list_makes_models first.
| Name | Type | Req | Description |
|---|---|---|---|
| asking_price | number | – | The price being asked for THIS car, in EUR — pass it to get a fair / above-market / below-market verdict. |
| fuel | string | – | Fuel: petrol, diesel, hybrid, electric |
| gearbox | string | – | Gearbox: manual or automatic |
| hp | integer | – | Power in hp (sharpens the comparison) |
| km | integer | yes | Mileage in km |
| make | string | yes | Full brand name in Latin — 'Renault', 'Volkswagen' (not 'VW'), 'Peugeot', 'Seat'. |
| model | string | yes | Short model name WITHOUT engine or trim — 'Clio' (not 'Clio 1.5 dCi'), 'Golf' (not 'Golf TSI'). |
| year | integer | yes | Registration year |
No output schema declared.
No examples provided.
contact_me ~139
Send a contact request to TransparentCars so a human gets in touch. Only call this when the user explicitly asks to be contacted, provides their own name and a phone or email, AND agrees to share those details — pass consent=true only then. Submitting shares the provided contact details per the TransparentCars 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 |
| contact | string | yes | A phone number or email where they can be reached |
| message | string | – | What they want / their question |
| name | string | yes | The person's name (as they gave it) |
No output schema declared.
No examples provided.
cost_to_own ~198
Estimate a car's yearly running-cost floor in Portugal — the annual IUC road tax (Imposto Único de Circulação) every owner pays, plus a plain running-cost framing. Needs engine displacement (cc), CO₂ (g/km), fuel and first-registration year. Use this to help a buyer budget the true cost of keeping a car, beyond the sticker price.
| Name | Type | Req | Description |
|---|---|---|---|
| cc | integer | yes | Engine displacement in cm³, e.g. 1200 |
| co2 | number | yes | CO₂ emissions in g/km, e.g. 120 |
| fuel | string | yes | Fuel: petrol, diesel, hybrid, phev, electric, lpg |
| month | integer | – | First-registration month (1-12), refines the CO₂ regime |
| used | boolean | – | Used vehicle (true, default) |
| year | integer | yes | First registration year, e.g. 2016 |
No output schema declared.
No examples provided.
get_car ~55
Get full details for one car in TransparentCars stock by its slug (from a search_inventory link, e.g. 'renault-clio-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) TransparentCars can search and price — or, given a make, that brand's models — using the exact strings the other tools expect. Call this FIRST (or whenever unsure of spelling) and pass the returned values verbatim into search_inventory / check_fair_price. 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. 'Renault'. Omit to get the list of brands. |
No output schema declared.
No examples provided.
search_inventory ~309
Search TransparentCars' current stock of budget used cars in Portugal — honestly listed, everyday cars for the local market. Filter by make, model, fuel, gearbox and max price. 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 ('Golf' not 'Golf 1.5 TSI', 'Clio' not 'Clio dCi'). Put the fuel in the fuel field, not the model. If unsure of the spelling, call list_makes_models first.
| Name | Type | Req | Description |
|---|---|---|---|
| fuel | string | – | Fuel: petrol, diesel, hybrid, phev, electric, lpg |
| gearbox | string | – | Gearbox: manual or automatic |
| limit | integer | – | Max results (default 20) |
| make | string | – | Full brand name in Latin, as the market lists it — 'Renault', 'Volkswagen' (not 'VW'), 'Peugeot', 'Seat'. |
| max_price | number | – | Maximum price in EUR |
| min_year | number | – | Earliest registration year |
| model | string | – | Short model name WITHOUT engine or trim — 'Clio' (not 'Clio 1.5 dCi'), 'Golf' (not 'Golf TSI'). |

io.github.transparentpt/mcp exposes 6 tools: search_inventory, get_car, check_fair_price, cost_to_own, list_makes_models, contact_me. Their descriptions and schemas cost roughly 1,163 tokens of context every time the server is loaded.
Is the io.github.transparentpt/mcp server still maintained?
io.github.transparentpt/mcp is still listed as active in the MCP registry. We last reached this channel on 22 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
