Native AI Integration
Connect Claude, Microsoft Copilot, or your own AI tools directly to Lexplorer. Your AI can perform legal research without leaving the application.
Integrate Lexplorer into Your Workflows
The Lexplorer MCP Server connects Claude, Cursor, Microsoft Copilot, custom AI agents, and other MCP-compatible assistants directly to legal search. Your assistant can research current Swiss sources instead of relying on model knowledge alone.
Connect Claude, Microsoft Copilot, or your own AI tools directly to Lexplorer. Your AI can perform legal research without leaving the application.
Search, detail retrieval, and document access are available as defined tools. Assistants can retrieve current judgments, statutes, publications, and tax-law sources.
Add the Lexplorer MCP URLs to your client and authenticate with a Lexplorer login or API key, depending on the client. Lexplorer Law MCP runs at law.lexplorer.ch/mcp; Lexplorer Tax MCP runs at mcp-tax.lexplorer.ch/mcp.
Connect your documents in the workspace to Claude or ChatGPT. You decide which folders the AI tool sees, and it only sees anonymised content from them.
You share individual folders. Claude and ChatGPT see nothing else.
Names and other personal data are replaced before Claude or ChatGPT see a document.
Both only see placeholders such as “Person A” and never receive the mapping.
Your files themselves stay with Lexplorer in Switzerland and the EU.
MCP and Skills solve different problems: MCP provides tools and data, while Skills define professional procedure. Together they create controlled legal research with sources, citation rules, and auditable steps.
The Model Context Protocol is the interface between the AI assistant and Lexplorer. It enables search, detail retrieval, and document access through explicitly allowed remote tools.
The Lexplorer + Tax Skill defines which sources to check, how to deepen results, and how to formulate answers with citations.
MCP delivers current data; the Skill adds research planning, filter logic, citation style, and quality checks. This reduces hallucinations and makes the process reviewable.
There are two MCP endpoints: Lexplorer Law MCP for court rulings, federal and cantonal law with citation verification, and Lexplorer Tax MCP for specialized tax research.
https://law.lexplorer.ch/mcpFederal Supreme Court rulings (BGer/BGE/BVGer), federal law (SR), legislative materials and cantonal statutes.
https://mcp-tax.lexplorer.ch/mcpILE and further public tax law sources: a large database as per the coverage report.
There is only one shared Skill for both MCPs. Please delete previous Lexplorer Skills and add only the current Lexplorer Research Skill.
Lexplorer is connected directly in the AI client: add the URL, connect with OAuth or an API key depending on the client, allow the tools, and test them in chat.
Lexplorer is available in ChatGPT as two plugins, one for legal questions and one for tax questions. The research instruction is already included, no separate skill is needed.
The sources are presented in two tiers: Lexplorer Law MCP covers all public statutes and court decisions at federal and cantonal level. Lexplorer Tax MCP additionally covers all tax-relevant public sources at federal and cantonal level, including administrative practice and cantonal tax manuals, as well as the ILE-HSG publications.
