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 →

Endpoint Security57
Transport & Reachability100
Schema Quality & AI Usability73
  • AI-judged instruction clarity (excellent).Pass
  • 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. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management23
  • Stability observed for 7 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
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

MCP tools — 3 exposed · ~333 tokens

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.

Tool Tokens
check_ico_insolvency ~80

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).

NameTypeReqDescription
icostringyesCzech IČO — 7 or 8 digits.

No output schema declared.

No examples provided.

poll_isir_events ~107

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.

NameTypeReqDescription
since_idintegerLast seen event id. Use 0 to start from the beginning of recorded ISIR history (~2008).

No output schema declared.

No examples provided.

search_person_insolvency ~146

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.

NameTypeReqDescription
dobstringDate of birth, YYYY-MM-DD. Optional but strongly recommended — common names produce many false positives without DOB.
namestringyesFull name in any case (Czech diacritics tolerated). E.g. "Pavel Novák" or "Jana Svobodová".
only_activebooleanWhen true (default), return only currently active proceedings. False also returns closed/dismissed.

No output schema declared.

No examples provided.
