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 → 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 Usability80
- 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 989 tokens (~247/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 Management3
- Stability observed for 1 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
How do I install the AutoIsto MCP server?
AutoIsto is a hosted endpoint at https://www.autoisto.sk/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

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 asking price ~253
Use this when the user asks how much a car model costs in Slovakia, or whether a price for a model is reasonable. Returns the median ASKING price of the brand/model (optionally one model year) in AutoIsto's current offer, the sample size, the price range and the date. The median is omitted below 20 cars with a plain price. These are prices sellers ask, not sale prices; mileage and equipment move the price, so present it as a guide. Do not use it for valuing a specific car's condition, for new-car prices or for markets outside Slovakia.
| Name | Type | Req | Description |
|---|---|---|---|
| brand | string | yes | Car brand, e.g. Škoda, Volkswagen, BMW (abbreviations such as VW work). |
| model | string | – | Model, e.g. Octavia, Golf, X5, Rad 3, C trieda (English names such as 3 Series or C-Class also work — the interpretation is returned). Versions, body variants and generations (RS, Variant, B8) are no… |
| year | integer | – | Model year, only together with model. |
| Name | Type | Req | Description |
|---|---|---|---|
| asOf | string | yes | Date of the figures (YYYY-MM-DD). |
| brand | string|null | yes | – |
| found | boolean | yes | – |
| interpretation | string|null | yes | How the model name was understood when AutoIsto knows it under another name ("3 Series" → Rad 3, "320d" → Rad 3). Tell the user. |
| listedCount | integer | yes | Cars of this brand/model(/year) in the offer today. |
| maxPriceEur | – | yes | – |
| medianAskingPriceEur | – | yes | Median ASKING price; null when fewer than 20 cars have a plain price. |
| minPriceEur | – | yes | – |
| model | string|null | yes | – |
| notApplied | string|null | yes | Part of the requested model the figures do NOT reflect (version, body, generation, e.g. "RS", "Variant", "B8"): figures cover the whole model. Tell the user. |
| note | string|null | yes | – |
| sampleSize | integer | yes | Cars the median is computed from. |
| scope | string | yes | What the figures cover. "brand" when no model was given — a year is applied only together with a model, see note. |
| url | string|null | yes | Model page on www.autoisto.sk. |
| year | – | yes | – |
No examples provided.
search_cars Search used cars ~374
Use this when the user wants to find a used car for sale in Slovakia — by brand, model, body type, fuel, gearbox, year, price, mileage, power or town/district. Covers listings sellers published on AutoIsto directly and public listings from Slovak car portals. Pass the criteria as ONE short phrase in Slovak (Czech also works), with numbers as the user said them. Examples that are fully understood: "škoda octavia kombi diesel automat od 2017 do 15000 €", "suv automat do 25000 €", "bmw x5 diesel od 2019 do 40000 €", "kombi do 10000 € Žilina". Use at most ONE body type per call (kombi, SUV, sedan, hatchback, liftback, van, kupé, kabriolet, dodávka); for two body types make two calls. Leave out filler and wishes that are not filters (rodinné, auto, do mesta, spoľahlivé) and equipment (ťažné, panoráma) — 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 (Slovakia, prices in EUR); no new-car configurators, rentals, leasing offers or cars abroad; the offer changes daily, so a car may already be sold.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | yes | Concrete criteria in Slovak or Czech, e.g. "bmw x5 diesel od 2019 do 40000 €" or "kombi do 10000 € Žilina". |
| Name | Type | Req | Description |
|---|---|---|---|
| allResultsUrl | string | yes | All matching cars on www.autoisto.sk. |
| 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 dropped because nothing matched exactly. |
| totalMatches | integer | yes | How many cars in the offer match (after relaxing, if any). |
| understood | array | yes | Filters AutoIsto read from the phrase, in Slovak (e.g. Škoda, Octavia, do 15 000 €). |
