Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions · remote - your agent's requests go to isir.cz-agents.dev

endpoint auth accepted our unauthenticated MCP initialize - no credentials needed to connect

license MIT - declared in the repository

npm package @czagents/isir - the @czagents scope differs from the repo owner (martinhavel); confirm it's the project's official package

registry vendor namespace dev.cz-agents - domain-verified with the official MCP registry

The 3 tools it gives your agent

Extracted from the project's README - what isir lets an agent do.

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:
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
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 answe
