Leksio

Leksio connects Claude to the Leksio SIP database of Polish legal acts, court judgments, tax rulings and regulator documents from official sources, including ZUS social-insurance rulings, positions and decisions of the Polish Financial Supervision Authority (KNF), decisions of the President of the data protection authority (UODO) and the UOKiK register of unfair contract terms. It helps lawyers, tax advisers and businesses find source documents for legal research.

Search by topic, case number or statutory citation. Read a judgment's disposition, reasoning or a selected passage. Compare the positions of courts, authorities and parties, and retrieve available statutory wording for a specified date. Results link directly to documents at sip.leksio.pl.

Leksio provides sources, metadata and warnings about unverified legal dates or incomplete material. AI-generated theses are labelled and do not replace source text. The database is not exhaustive, and available text does not always establish the law in force on a requested date. Claude prepares the answer from retrieved material; findings require assessment against the facts of each case.

A verified Leksio account and acceptance of the MCP Rules are required. Access follows the entitlements of the connected account. Research allowance per allowance period: free 5, SIP Pro 50, SIP Pro+ 150. Checking account status and starting an unused task do not consume an allowance; one research is counted at the first accepted source search or read. Each research supports up to 50 tool calls and lasts up to 24 hours, ending no later than the allowance renewal. Rate and data-transfer limits prevent bulk extraction.

All tools are read-only. The connector does not file documents, access private notes, issue invoices or change subscriptions. It does not replace legal advice. Leksio does not store the content of your questions. Leksio sp. z o.o. operates the service.
