Isir is an MCP server with 3 tools an agent can call, among them check_ico_insolvency, poll_isir_events, search_person_insolvency. It answers at https://isir.cz-agents.dev/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 5 September 2026; the last check, on 18 October 2026, succeeded.
Czech insolvency register (ISIR) — active/historical insolvency & bankruptcy by IČO or person.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
check_ico_insolvency | 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). Inputs: ico |
poll_isir_events | 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 Inputs: since_id |
search_person_insolvency | 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. Inputs: name, dob, only_active |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://isir.cz-agents.dev/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: dev.cz-agents. Endpoint host: isir.cz-agents.dev. ARD identifier: urn:air:dev.cz-agents:mcp:isir.
First indexed 31 August 2026. The tools are exactly what the server returned; nothing on this page
