Linde MCP Server

Ein MCP (Model Context Protocol) Server, der KI-Modellen Zugriff auf linda.lindeverlag.at (Linde Datenbank) gibt. Suche, Dokument-Volltext, Ausgaben-Inhaltsverzeichnisse, Kommentare und See-Also-Verweise über stdio.

Wichtig: Linda nutzt IP-basierten Zugriff (z.B. WU-Wien-Netz, VPN). Es ist kein Login erforderlich — der MCP-Server muss einfach vom WU-Netz aus erreichbar sein.


Features

  • Suche: Volltextsuche über linda.lindeverlag.at/SearchResults/ mit Paginierung, Sortierung (Relevanz/Datum) und Filter (My/All, Archiv).
  • Autocomplete: Vorschläge über search/autocompletesuggestions.
  • Dokument-Volltext: Titel, Autor, Literaturquelle, Rechtsnorm-Verweise, Literaturverzeichnis und Volltext.
  • Ausgabe (Magazin): Inhaltsverzeichnis gruppiert nach Sektionen.
  • Kommentare: Liste der verfügbaren Kommentare (My/All).
  • See-Also: Verwandte Rechtsnormen, Literatur und Judikatur.
  • Auth-Status & Cookie-Set: Optional — für hinter Paywall liegende Inhalte können manuell Cookies gesetzt werden.

Konfiguration & Zugang

Linda ist über IP autorisiert (z.B. WU-Wien-Campus-Netz, eduroam, oder VPN zum WU-Netz). Keine Credentials nötig.

Optionale Cookie-Authentifizierung (für Premium-Inhalte):

  • Environment Variable: LINDA_COOKIE="DbSessionVWINASP02=...; bis_logonguid=..."
  • Command Line Flag: --cookie "DbSessionVWINASP02=...; bis_logonguid=..."

Cookie-Werte aus dem Browser: DevTools → Application → Cookies → linda.lindeverlag.at und .lindeverlag.at.

Direkt via npx (empfohlen)

npx -y github:blueqwertz/linda-mcp

Mit Cookie:

LINDA_COOKIE="DbSessionVWINASP02=...; bis_logonguid=..." npx -y github:blueqwertz/linda-mcp
