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 → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- 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 Usability78
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1076 tokens (~269/item across 4 items; 3 tools + 1 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 Management90
- Stability observed for 27 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
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
- Supports UI / widget rendering.Pass

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 →
get_car_details Get car details ~129
Use this when the user asks for more about one specific car returned by search_cars (engine power, body, colour, price history, how long it has been listed). Requires the car id from search_cars; do not guess ids. Returns technical data and the AutoIsto price verdict; it does not return the seller's name, phone, description, VIN or licence plate — for contact the user opens the car's url. If the car is no longer in the offer, found is false.
| Name | Type | Req | Description |
|---|---|---|---|
| carId | string | yes | The id of a car from search_cars results. |
| Name | Type | Req | Description |
|---|---|---|---|
| car | – | yes | – |
| found | boolean | yes | – |
| note | string|null | yes | – |
No examples provided.
get_model_price Get typical price of a model year ~292
Use this when the user asks how much a car model of a given year costs in the Czech Republic, or whether a price for it is reasonable. Returns, for one brand, model and model year: the median ASKING price in AutoIsto's current offer (any mileage) and the median LAST price at which such cars left the offer, each with its sample size, and the month. A figure is omitted when its sample is too small. Asking prices are what sellers ask, not sale prices, and a car leaving the offer is not proof of a sale; mileage and equipment move the price, so present it as a guide. Requires a year; if the user did not give one, ask. Do not use it for valuing a specific car's condition, for new-car prices or for markets outside the Czech Republic.
| Name | Type | Req | Description |
|---|---|---|---|
| brand | string | yes | Car brand, e.g. Škoda, Volkswagen, BMW (abbreviations such as VW work). |
| model | string | yes | Model, e.g. Octavia, Golf, X5, Řada 3, Třída C (English names such as 3 Series or C-Class also work — the interpretation is returned). Versions, body variants and generations (RS, Combi, B8) are not… |
| year | integer | yes | Model year. |

| exitPriceLowerQuartileCzk | – | yes | – |
| exitPriceUpperQuartileCzk | – | yes | – |
| exitSampleSize | – | yes | – |
| found | boolean | yes | – |
| interpretation | string|null | yes | How the model name was understood when AutoIsto knows it under another name ("3 Series" → Řada 3, "C-Class" → Třída C). Tell the user. |
| medianAskingPriceCzk | – | yes | Median ASKING price of this model and year in today's offer (any mileage); null when the sample is too small. |
| medianExitPriceCzk | – | yes | Median of the LAST price at which cars of this model and year left AutoIsto's offer (removed from the offer — not necessarily sold); null when too few. |
| model | string|null | yes | – |
| month | string|null | yes | Month the figures are for (YYYY-MM, Prague time). |
| notApplied | string|null | yes | Part of the requested model the figures do NOT reflect (version, body, generation, e.g. "RS", "Combi", "B8"): figures cover the whole model. Tell the user. |
| note | string|null | yes | – |
| url | string|null | yes | Search for this model and year on www.autoisto.cz. |
| year | – | yes | – |
No examples provided.
search_cars Search used cars ~406
Use this when the user wants to find a used car for sale in the Czech Republic — by brand, model, body type, fuel, gearbox, year, price, mileage, power, number of seats or town/region. Covers listings sellers published on AutoIsto directly and public listings from Czech car portals. Pass the criteria as ONE short phrase in Czech (Slovak also works), with numbers as the user said them and prices in CZK. Examples that are fully understood: "škoda octavia kombi nafta automat od 2017 do 350000 Kč", "suv automat do 600000 Kč", "bmw x5 diesel od 2019 do 1000000 Kč", "kombi do 250000 Kč Brno", "9 místná dodávka". Use at most ONE body type per call (kombi, SUV, sedan, hatchback, liftback, MPV, kupé, kabriolet, dodávka, pick-up); for two body types make two calls. Leave out filler and wishes that are not filters (auto, do města, spolehlivé) and equipment (tažné, panorama) — unknown words are not applied and are listed in notUnderstood. Returns up to 10 cars with price verdicts, what was understood, which criteria were relaxed when nothing matched exactly, which words were not applied, and a link to all results. Limits: only cars currently listed on AutoIsto (Czech Republic, prices in CZK); no new-car configurators, rentals, leasing offers or cars abroad; the offer changes daily, so a car may already be sold. Seat counts of 6+ are estimated from the model.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | yes | Concrete criteria in Czech or Slovak, e.g. "bmw x5 diesel od 2019 do 1000000 Kč" or "kombi do 250000 Kč Brno". |
| Name | Type | Req | Description |
|---|---|---|---|
| allResultsUrl | string | yes | All matching cars on www.autoisto.cz. |
| cars | array | yes | Up to 10 cars, AutoIsto's best-value order (closest to the budget when a budget was given). |
| notUnderstood | array | yes | Words from the query that were NOT applied as filters (unknown words, two body types at once, equipment). Empty together with empty relaxed = the results match everything in the query. |
| note | string|null | yes | – |
| query | string | yes | – |
| relaxed | array | yes | Criteria from the phrase dropped because nothing matched exactly, in Czech; the returned cars do NOT meet them. |
| totalMatches | integer | yes | How many cars in the offer match (after relaxing, if any). 0 = nothing matched even after relaxing. |
| understood | array | yes | Filters from the phrase that the returned cars match, in Czech (e.g. Škoda, Octavia, cena do 300 000 Kč). |
