Ris Mcp Ts MCP Server

RIS MCP Server

An MCP (Model Context Protocol) server that gives AI assistants access to Austria's official legal database — the Rechtsinformationssystem (RIS).

Ask your AI assistant about Austrian law, and it will search and retrieve legal documents directly from the official government API. No API key required.

What You Can Do

Once connected, you can ask your AI assistant things like:

"What does Austrian law say about tenancy rights?"

"Find Constitutional Court decisions on freedom of expression."

"Show me §1295 of the ABGB (Austrian Civil Code)."

"What laws about climate protection were published in 2024?"

"Look up the building code for the province of Salzburg."

"Get the full text of document NOR40052761."

The server translates these natural language requests into structured API calls against the RIS Open Government Data API.

Features

• 12 specialized tools covering all major RIS collections
• Federal law (ABGB, StGB, UGB, ...) and state law for all 9 provinces
• Court decisions from 16 court types (Supreme Court, Constitutional Court, Administrative Court, ...)
• Law gazettes — Federal (BGBl) and state (LGBl)
• Government bills, ministerial decrees, cabinet protocols
• Full document retrieval with smart prefix-based routing
• Change history tracking across 36 application types
• Interactive result list (MCP Apps) in hosts that support it — with a full text answer everywhere else
• Markdown and JSON output formats
• Free and open — uses Austria's Open Government Data API, no API key needed

Quick Start

Run directly without installation:

pnpm dlx ris-mcp-ts

Or install globally:

pnpm add -g ris-mcp-ts

Configuration

Claude Desktop

Add to your Claude Desktop config (Settings > Developer > Edit Config):

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "ris": {
      "command": "npx",
      "args": ["-y", "ris-mcp-ts"]
    }
  }
}

Note: The "Add custom connector" UI in Claude Desktop only supports remote MCP servers (HTTP/SSE). Local stdio servers like this one must be configured via the JSON file.

Tip: You can also use pnpm dlx instead of npx in all configuration examples if you prefer pnpm.

Claude Code

Add to your project or user settings:

claude mcp add ris -- npx -y ris-mcp-ts

VS Code (GitHub Copilot)

Add to .vscode/mcp.json in your project:

{
  "servers": {
    "ris": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "ris-mcp-ts"]
    }
  }
}

Cursor

Add to .cursor/mcp.json in your project (or ~/.cursor/mcp.json for global access):

{
  "mcpServers": {
    "ris": {
      "command": "npx",
      "args": ["-y", "ris-mcp-ts"]
    }
  }
}

Windsurf

Add to your Windsurf MCP config at ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "ris": {
      "command": "npx",
      "args": ["-y", "ris-mcp-ts"]
    }
  }
}

Other MCP Clients

Any MCP-compatible client can connect via stdio transport:

npx -y ris-mcp-ts
# or: pnpm dlx ris-mcp-ts

Available Tools

Interactive Result List

One widget, all eleven search tools. There is a single interactive result list, and every search tool renders into it: federal law, state law, case law, the federal and state law gazettes, government bills, district authority announcements, municipal law, the miscellaneous collections, change history and the ordinance gazettes. The screenshots below are the same widget in two different hosts, not two different features.

ris_dokument opens a reader instead. A single document can run to a quarter of a million characters, far past what one answer may carry, so the viewer loads it section by section as you scroll, offers an outline to jump by where the document has one, and links back into RIS. The full text still reaches the chat either way — the widget is never the only copy.

Hosts that support the MCP Apps extension render the hits as an interactive list — page through results without retyping the search, open a document in the browser, or request its full text with one click. The widget follows the host's light or dark theme; the shots below show both.

Example Prompts

RIS is a German-language database, so these work best in German. Each of these lands on a different tool:

"Zeig mir das Verbrauchergewährleistungsgesetz" — ris_bundesrecht

"Finde aktuelle OGH-Rechtsprechung zu Verjährung" — ris_judikatur

"Was steht im Tiroler Landesrecht zum Naturschutz?" — ris_landesrecht

"Zeig mir BGBl. I Nr. 175/2021" — ris_bundesgesetzblatt

In a host without MCP Apps support the same prompts return the full text answer instead — see the table below.

The chat answer is always complete. The widgets are an addition to it, never a replacement — a host that does not render them loses nothing.

Tool Reference

Search Austrian federal laws such as ABGB, StGB, UGB, and more.

Inputs:

All parameters are optional. At least one search parameter (suchworte, titel, or paragraph) should be provided.

Note: applikation="Erv" (English translations) uses a different parameter vocabulary internally (SearchTerms/Title) and does not support paragraph/abschnitt_typ or fassung_vom.

Search state laws of the nine Austrian provinces.

Inputs:

Search court decisions from Austrian courts.

Inputs:

Available gerichtsbarkeit values (16):

Search the Federal Law Gazette (BGBl) — official publications of federal legislation.

Inputs:

Search State Law Gazettes (LGBl) — official publications of state legislation.

Inputs:

Search government bills — draft legislation submitted to parliament.

Inputs:

Retrieve the full text of a legal document by its ID or URL. Uses a dual strategy: direct URL access first, then search API fallback.

Inputs:

At least one of dokumentnummer or url is required. Long documents are truncated to 25,000 characters.

Supported document prefixes:

The full routing registry lives in DOCUMENT_ROUTES (src/client.ts); unknown prefixes fall back to a Justiz search.

Search announcements from district administrative authorities.

Note: Only available for: Niederoesterreich, Oberoesterreich, Tirol, Vorarlberg, Burgenland, Steiermark.

Inputs:

Search municipal law — local ordinances and regulations.

Inputs:

Additional parameters depend on the selected application. See Gr (municipal law) and GrA (official gazettes) specific parameters in the source code.

Search miscellaneous legal collections and specialized databases.

Inputs:

Available collections:

Each collection has additional specific parameters. See the tool description for details.

Track document creation, modification, and deletion across the RIS database.
