SuperFaktura MCP by usefulapi

The company the API key is working in (name, IČO, DIČ, IČ DPH, address, VAT-payer flag, bank accounts) and the remaining API quota (SuperFaktura's fair-use policy is 1000 requests per day and 31000 per month; every tool call here uses one request). Good first call. With all_companies=true also the other companies the user can access (their ids are the company_id of the login). GET /users/getUserCompaniesData.

WRITE: adds a new client to the SuperFaktura address book (only the name is required). Nothing is sent to the client. Not idempotent: calling twice creates two clients, so check superfaktura_list_clients first. POST /clients/create.

WRITE: creates ONE document in SuperFaktura for the user to review: type draft (concept, default), estimate (quote), order or proforma. A final regular invoice cannot be created here. It is NOT sent (no e-mail, no post), NOT marked paid or sent, and has no payment link or discount. Give an existing client_id (its name is read first with one extra GET /clients/view/{id}, so the call uses 2 requests of the daily quota) OR a new client's name (+ optional ico/dic/ic_dph/address...). Items: name, unit price without VAT, VAT rate, quantity. Not idempotent: pass a checksum (max 32 chars) so a timed-out call can be recovered with superfaktura_get_response_by_checksum instead of retried. POST /invoices/create.
