## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (intent_withdraw_intent).
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 69/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1167 tokens (~233/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 50/100
  - Stability observed for 15 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (80% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - All 2 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.
  - An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (5)

### `intent_publish_intent` (~377 tokens)

Watch new car listings for the user (needs the user's confirmation)

Use this when the user asks AutoIsto to keep watching Czech car listings for them over time (e.g. "let me know until March about an estate car under 300 000 CZK, not diesel"). This does NOT start watching by itself and takes no e-mail address or other personal data: it returns a consentUrl on www.autoisto.cz that the user must open themselves, enter their own e-mail there and confirm by clicking the link AutoIsto e-mails them. Never ask the user for their e-mail in the conversation and never open the link for them. An unconfirmed draft is deleted after 24 hours. Matching cars are e-mailed to the user and can also be read with intent_list_matches using the returned intentCode — keep it in the conversation. hiddenLimitCzk is optional: the most the user would pay, stored encrypted and never shown to sellers or returned by any tool; pass it only if the user said it. Matches come from listings AutoIsto CZ aggregates from the Czech market (its own sellers' listings and public listings from Czech car portals), so they cover only cars listed on AutoIsto CZ (Czech Republic, CZK) and may be incomplete.

Input parameters:

- `buyBy` (string): Date (YYYY-MM-DD) by which the user wants to buy; watching stops after it.
- `hiddenLimitCzk` (integer): Optional private maximum price in CZK; encrypted on receipt and never returned by any tool.
- `niceToHave` (string): Wishes that are not required (never filters), e.g. "tažné, automat".
- `statement` (string, required): What the car MUST be, as one short Czech (or Slovak) phrase with prices in CZK, e.g. "kombi do 300000 Kč ne diesel".

Output parameters:

- `buyBy` (string|null)
- `consentExpiresAt` (string): ISO time after which the unconfirmed draft is deleted.
- `consentUrl` (string): Page on www.autoisto.cz where the USER confirms the intent with their own e-mail. Show it unchanged.
- `hasHiddenLimit` (boolean): Whether a hidden limit was stored. Its value is never returned.
- `intentCode` (string): Secret code of this intent; use it with intent_get_intent, intent_list_matches and intent_withdraw_intent.
- `niceToHave` (string|null)
- `notUnderstood` (array): Words of the statement that are NOT watched for. Tell the person.
- `statement` (string)
- `status` (string): awaiting_consent = the user has not confirmed on the AutoIsto page yet; awaiting_email_confirmation = the user filled in the page and must click the link in the e-mail; active = AutoIsto is watching;…
- `understood` (array): What AutoIsto will watch for, read from the statement (in Czech). Tell the person before they confirm.

### `intent_get_intent` (~82 tokens)

Get the state of a car watch

Use this to check whether an intent created with intent_publish_intent is already confirmed by the user and active, waiting, expired or withdrawn. Requires the intentCode; returns the statement and dates only — never the user's e-mail, the hidden limit or any other personal data.

Input parameters:

- `intentCode` (string, required): The intentCode returned by intent_publish_intent.

Output parameters:

- `activeSince` (string|null)
- `buyBy` (string|null)
- `found` (boolean)
- `hasHiddenLimit` (boolean)
- `niceToHave` (string|null)
- `statement` (string)
- `status` (string): awaiting_consent = the user has not confirmed on the AutoIsto page yet; awaiting_email_confirmation = the user filled in the page and must click the link in the e-mail; active = AutoIsto is watching;…
- `validUntil` (string): Date (YYYY-MM-DD) until which the intent is watched (before confirmation: until the draft is deleted).

### `intent_list_matches` (~179 tokens)

List cars found for a car watch

Use this when the user asks what AutoIsto has found for an intent created with intent_publish_intent. These are the same cars AutoIsto e-mails to the user; this server cannot send messages into the conversation by itself. Requires the intentCode; optional since (ISO time) returns only newer matches. Returns at most 20 newest matches with the price in CZK and AutoIsto price verdict at the time of the match and a link. Before the user confirms the intent there are no matches. Matches come from listings AutoIsto CZ aggregates from the market, so they cover only cars listed on AutoIsto CZ and may be incomplete; a car may already be sold.

Input parameters:

- `intentCode` (string, required): The intentCode returned by intent_publish_intent.
- `since` (string): Only matches found after this ISO time.

Output parameters:

- `found` (boolean)
- `matches` (array)
- `more` (boolean): More matches exist than returned; call again with since.
- `status` (string): awaiting_consent = the user has not confirmed on the AutoIsto page yet; awaiting_email_confirmation = the user filled in the page and must click the link in the e-mail; active = AutoIsto is watching;…

### `intent_withdraw_intent` (~68 tokens)

Stop a car watch

Use this when the user wants AutoIsto to stop watching for an intent created with intent_publish_intent. Takes effect immediately; nothing more is e-mailed for it. Requires the intentCode.

Input parameters:

- `intentCode` (string, required): The intentCode returned by intent_publish_intent.

Output parameters:

- `found` (boolean)
- `status` (string)

### `intent_search_offers` (~225 tokens)

Search cars AutoIsto CZ offers today

Use this when the user wants to find a used car for sale in the Czech Republic now. Pass what they are looking for as one short phrase (Czech or Slovak works best), e.g. "toyota rav4 hybrid do 600000 Kč". Returns up to 20 cars from AutoIsto CZ's offer in its own order, each with a link to the car on www.autoisto.cz, plus what was understood, which words were not applied and what had to be relaxed. When suggestIntent is true (nothing or little found, or part of the phrase was dropped), offer the user intent_publish_intent with the same statement so AutoIsto CZ keeps watching. Results come from listings AutoIsto CZ aggregates from the Czech market and may be incomplete; no seller contact is returned.

Input parameters:

- `limit` (integer): At most this many cars (default 10; AutoIsto CZ returns at most 10).
- `statement` (string, required): What the user is looking for, e.g. "suv automat do 500000 Kč".
