Overview

AI-generated overview

Korpus connects an assistant to a multi-jurisdiction legal and tax corpus (FR, EU, LU, MC, AD) for citation resolution and claim verification.

What you can do
  • Resolve exact in-force text and SHA-256 hashes of legal citations across France, the EU, Luxembourg, Monaco and Andorra
  • Search recent case law and doctrine, for example on abrupt termination of established commercial relationships
  • Verify a legal claim and return a groundedness score
  • Look up legal and tax sources through a hosted corpus presented as scientific and hallucination-free
When to use it
Useful when an assistant must answer French, EU, Luxembourg, Monaco or Andorran legal and tax questions with traceable citations, exact article text and hashes, or when you want to check a legal statement against a source corpus.
Requirements
Remote hosted endpoint at korpus.lu over streamable HTTP; OAuth 2.1 authorization is required, and a Korpus account plus an API key generated in the account settings are needed to complete authorization. No environment variables or headers are declared.
Before you install
Requires an OAuth login and a Korpus API key, so account credentials are involved; the README does not state pricing, so check whether access is paid. Queries and the legal texts you look up are sent to the Korpus service. The claim that the corpus is hallucination-free is the provider's own description, not a guarantee.

Installation

In SourceWeft

  1. Open Korpus — Intelligence Juridique & Fiscale in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/lu.korpus%2Fkorpus/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
