Overview

Description from the maker (original English)

Czech insolvency register (ISIR) — active/historical insolvency & bankruptcy by IČO or person.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

You need

  • Runs in the cloudNothing to install; it connects over the internet
  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Common questions

Is Isir safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.4) reached the registry 5 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, Kanal Varna — drains, leaks & plumbing (Varna, BG)

@czagents/isir

Czech insolvency register (ISIR) lookups — check whether a company or person has active or historical insolvency proceedings, bankruptcy, or debt-relief filings. Direct monitoring and lookup from the official Ministry of Justice register. Essential for vendor and counterparty risk checks.

Status

v0.x is alpha — the direct SOAP integration is in progress and current responses may be empty for some queries. Behaviour is expected to stabilise during the 0.x line; the surface (tool names, schemas) is settled.

Install

npm install -g @czagents/isir

Usage with Claude Desktop

{

"mcpServers": { "isir": { "command": "npx", "args": ["-y", "@czagents/isir"], "env": { "ISIR_SOAP_ENABLED": "1" } } } }

Tools

check_ico_insolvency

Use it to check whether a Czech company identified by IČO has an active ISIR insolvency proceeding. Do not use a clean result as a historical insolvency screen: this tool checks active proceedings only, and an unavailable/unconfigured service yields no verdict.

{"ico":"26168685"}
search_person_insolvency

Use it to search an individual by name, preferably with date of birth, for active personal insolvency proceedings; set only_active to false to include closed or dismissed cases. Do not use a name alone for an identity-critical decision when the person has a common name; provide the date of birth or verify manually.

{"name":"Jan Novák","dob":"1980-05-15","only_active":true}
poll_isir_events

Use it to consume the append-only ISIR event feed for monitoring or index backfill, advancing the next request with the returned last_id. Do not use it to answer an ad-hoc question about one company or person; use the dedicated lookup tool.

{"since_id":0}
