search_companiesSearch and filter Polish KRS companies (spółki).No findings
Why it is in this group
- The name "search_companies" says "search": a word for reading.
Description, as the server wrote it
Search and filter Polish KRS companies (spółki). Compabase also holds the full CEIDG/JDG register; this tool does not browse JDG — those without a public contact email are hidden because of RODO. Default `fields=summary` returns a compact row (name, NIP, KRS, location, PKD, latest financials, email/phone/website) — small enough for MCP clients. `fields=contacts_only` is name/NIP/KRS/city/email/phone/website only. `fields=full` returns every company_search column plus contacts and may exceed client size limits. Use for rankings, sector filters, city/county/region browsing, name search, or NIP/KRS lookup. When a PKD is mostly JDG, a sparse result includes a `hint` (full CEIDG is in the database; listing is RODO-gated). Do not call export_companies just to get a handful of emails or phones.
Annotations the server declares

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Run the operations that matter as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
