Generate a Polish proforma invoice PDF. Pass the full invoice JSON (with sprzedawca, nabywca, pozycje, etc.) as a string. Returns invoice number and base64-encoded PDF.
AI agents use generate_proforma to create or update resources in Fakturka Api — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Fakturka Api environment.
This tool creates and generates new financial documents (proforma invoices) with assigned invoice numbers. While it does not directly move money or create binding payment obligations (which would be Financial), it produces official invoice artifacts that are reversible—proformas can be replaced, corrected, or voided.
From the tool's definition Tool description states it 'Generate[s] a Polish proforma invoice PDF' and 'Returns invoice number and base64-encoded PDF'. The action creates a new invoice document (proforma invoice) with an assigned invoice number.

Register the Fakturka Api MCP server in PolicyLayer and add a rule for generate_proforma: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Fakturka Api. Nothing to install.
generate_proforma is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the generate_proforma rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for generate_proforma. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
