Tools for a Polish business

From invoices to a trial balance. These are selected public MCP tools for JDG and sp. z o.o. businesses. Access depends on permissions and company setup.

Start with a specific task

You do not need to know tool names. Describe your goal, identify the company and period, and let the assistant choose the calls.

InvoicePrepare a PLN invoice for this customer. Show me the preview before sending it.

Month-end reviewReview last month’s KPiR and explain which transactions were excluded.

Company reviewShow my company’s trial balance and the lines in its existing financial statement.

KSeF connectionCheck the KSeF status and when invoices were last imported. I will enter the token in Norman.

Ask about a specific company and period

Example prompts, not results from your account. The assistant should show returned records or explain when data is unavailable.

	Example prompt	What to review
JDG / KPiR	Show my JDG’s KPiR totals and excluded transactions for September 2026.	The period, entries and exclusion reasons. Missing data is not a zero balance.
Sp. z o.o.	Show my company’s trial balance for September 2026.	The selected company, accounts and period in its full books. This is not a bank balance.
JPK	Summarise sales and purchases in the JPK register for September 2026.	Entries, totals and exclusions. Reading does not submit a return.
UPO	Check whether an existing JPK filing has a UPO receipt.	The specific filing’s status and availability of its official receipt.

Good to know

Does MCP access change my plan?

No. The connection uses your account permissions. Access to paid workflows still depends on the company’s plan.

Can I review KPiR through Claude or ChatGPT?

Yes, after connecting Norman and selecting a Polish sole proprietorship using KPiR. Ask for entries, totals or excluded transactions for a specific period. Check the company and dates before interpreting the result. Access depends on permissions and company setup.

Will MCP submit my JPK_V7 or sign a return?

No. Polish MCP tools read JPK register data, tax estimates and existing filing statuses with UPO availability. They do not sign or submit returns. Continue in the relevant workflow in Norman.

Are all tools read-only?

No. Tools can also create or update invoices and transactions. KPiR and estimate reads may synchronise derived records. A settings proposal stores a pending proposal, but only the owner applies it in Norman. Review an action’s effects before authorising it.

Where do I enter a PESEL or KSeF token?

Directly in settings after signing in to Norman, not in a conversation with an assistant. MCP can check the KSeF connection status without reading the token.

Do I need a separate MCP URL for Poland?

No. Use https://mcp.norman.finance/mcp, sign in with OAuth and select the correct company. Its country and accounting setup determine the applicable workflows, not the conversation language. A Polish-language conversation does not change a German company’s jurisdiction.
