## 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 2026-08-03.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 3 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - 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**: 73/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 463 tokens (~154/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability observed for 7 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.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (3)

### `check_ico_insolvency` (~80 tokens)

Check whether a Czech company (by IČO) has any active insolvency proceeding in ISIR. Returns spisová značka, start date, and current phase if found. Returns "no record" if not (which is also informative).

Input parameters:

- `ico` (string, required): Czech IČO — 7 or 8 digits.

### `search_person_insolvency` (~146 tokens)

Search ISIR for an individual person (FO) by name and optional date of birth. Returns active insolvency proceedings (oddlužení / osobní bankrot). Used to screen statutory persons in KYC and DD workflows.

Input parameters:

- `dob` (string): Date of birth, YYYY-MM-DD. Optional but strongly recommended — common names produce many false positives without DOB.
- `name` (string, required): Full name in any case (Czech diacritics tolerated). E.g. "Pavel Novák" or "Jana Svobodová".
- `only_active` (boolean): When true (default), return only currently active proceedings. False also returns closed/dismissed.

### `poll_isir_events` (~107 tokens)

Pull a batch of recent ISIR events (insolvency register publications) since the given event id. ISIR is an append-only feed — each call returns up to ~1000 events newer than `since_id`. Use `last_id` from response as next `since_id`. Useful for compliance monitoring or to back-fill an index.

Input parameters:

- `since_id` (integer): Last seen event id. Use 0 to start from the beginning of recorded ISIR history (~2008).
