Tools of pl-firmy: Polish company check
	Description		Read-only	Idempotent	Open world
`add_watch`Once a day, check one Polish contractor (one NIP) in public registries. The check reads VAT status and white-list bank accounts from the Ministry of Finance, and reads KRS for liquidation, bankruptcy or restructuring. It stores the NIP, any bank accounts you choose to watch, an optional label, and a snapshot of that check. Change alerts go only to the e-mail of the signed-in account owner (the OAuth-linked KSeF Płatności account, or the owner of the almmity API key). It never e-mails the contractor and it never contacts anyone else. It does not accept a webhook address or another e-mail address. If this account has no e-mail on file, the watch is still stored and alerts are visible with list_watches and in the panel. Adding the same NIP again updates that watch. Stop monitoring with remove_watch. Requires sign-in (OAuth) or an almmity API key. Does not accept a KSeF token or a password.	Once a day, check one Polish contractor (one NIP) in public registries.
