This server provides AI agents with access to the official German Federal Legal Information Portal (rechtsinformationen.bund.de) for authoritative German legal research with proper citations.
Core Tools:
semantische_rechtssuche (Primary): Intelligent search across both legislation and case law — automatically translates English queries to German, corrects misconceptions, extracts legal references (§), and decomposes German compound words for better results.
deutsche_gesetze_suchen (Secondary): Search German federal laws, ordinances, and administrative provisions.
rechtsprechung_suchen (Secondary): Search federal court decisions (BGH, BVerfG, BAG, BFH, BSG, BVerwG), with optional filtering by court, date range, and document type.
alle_rechtsdokumente_suchen (Secondary): Search across all document types simultaneously.
dokument_details_abrufen (Retrieval): Fetch full text of a specific document via URL, ELI, or ECLI identifier.
gesetz_per_abkuerzung_abrufen (Direct Lookup): Retrieve a federal law directly by its standard abbreviation (e.g., "BGB", "StGB", "SGB X").
Key Features:
Automatic English-to-German translation of legal terms
German compound word decomposition (e.g., "Mieterhöhungsantrag" → "Mieterhöhung")
Returns human-readable HTML URLs and machine-readable JSON API URLs for citations
Fallback search mechanisms to avoid zero results
Model-agnostic: works with Claude, Qwen, DeepSeek, LLaMA, and others
Use Cases: Look up specific law paragraphs (e.g., § 558 BGB), research legal rights and obligations, find recent federal court decisions, answer German administrative law questions with cited sources, and cross-reference legislation and case law.

Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Rechtsinformationen Bund DE MCP Server Wie lange kann ich in Elternzeit gehen?"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
An MCP (Model Context Protocol) server that provides access to the official German Federal Legal Information Portal (rechtsinformationen.bund.de). Any AI agent can use this server for German legal questions to provide authoritative, fact-based answers with proper legal citations from official sources.
The fastest way to get started:
Run the setup script:
./quick-setup.shRestart Claude Desktop completely (or your MCP client)
Test with: "Wie lange kann ich in Elternzeit gehen?"
Related MCP server: Open Legal Data MCP Server
AI agents will automatically use this MCP server for:
German legal questions ("What happens if I miss a Jobcenter appointment?")
Legal rights and obligations ("How long can I take parental leave?")
Court decisions and precedents ("Recent BGH decisions on trademark law")
Specific law lookups ("What does § 32 SGB II say?")
Administrative law questions ("When do I need a hearing in administrative proceedings?")
Purpose: Ensures all German legal answers are grounded in official sources with proper citations.
Full-text search across German federal laws and legislation
Case law search through German federal court decisions (BGH, BVerfG, BAG, BFH, BSG, BVerwG)
Intelligent search with English-to-German translation and misconception correction
German compound word decomposition (e.g., "Mieterhöhungsantrag" → "Mieterhöhung")
HTML URLs for users (clickable, readable documents)
Model-agnostic - works with Claude, Qwen, DeepSeek, LLaMA, and other models
✅ HTML URLs: Returns human-readable web links, not just JSON API URLs ✅ Compound word handling: Decomposes German compound words for better search ✅ Fallback search: Never returns zero results for valid queries ✅ English translation: Automatically translates English legal terms to German ✅ Type coercion: Works with models that pass strings instead of numbers
The server provides 6 specialized tools with intelligent routing:

# Rebuild
npm install && npm run buildSymptom: Agent makes 10+ tool calls without stopping
Solution:
Set recursionLimit: 5 in agent config
Add explicit STOP instructions
Use semantische_rechtssuche as primary tool
Symptom: Agent doesn't include URLs despite MCP response containing them
Solution:
This is a model behavior issue, not server issue
Strengthen instructions: "MUST include ALL URLs"
Consider agentic architecture with dedicated citation agent
Symptom: "Received tool input did not match expected schema"
Solution: ✅ Fixed - server now handles string→number type coercion
User: "Wie lange kann ich in Elternzeit gehen?"
Agent: Uses semantische_rechtssuche("Elternzeit Dauer")
→ Finds BEEG § 15
→ Answer: Up to 3 years per child
Sources:
1. https://testphase.rechtsinformationen.bund.de/.../regelungstext-1.htmlUser: "Was passiert bei einem Mieterhöhungsantrag?"
Agent: Uses semantische_rechtssuche("Mieterhöhungsantrag")
→ Decomposes to "Mieterhöhung"
→ Finds § 558 BGB
→ Answer: Rent increase procedures
Sources:
1. https://testphase.rechtsinformationen.bund.de/.../regelungstext-1.htmlUser: "What are employee rights during company restructuring?"
Agent: Uses semantische_rechtssuche(translates to "Arbeitnehmerrechte Betriebsumstrukturierung")
→ Finds KSchG, BetrVG
→ Answer: Dismissal protection and works council participation

Coverage:
✅ Current federal legislation
✅ Federal court decisions (2010-2024)
✅ Historical versions of laws
⚠️ Amendment laws (partial coverage)
❌ Legislative materials (not included)
Problem: Temporal filters may exclude relevant results when laws enacted in one year become effective in another.
Example: Searching for "§ 44 SGB X Änderung 2021" with date filter 2021 misses the 7. SGB-IV-Änderungsgesetz from June 2020 (effective January 1, 2021).
Workaround: Search without date filters, manually review effective dates.
Problem: Amendment laws are poorly indexed and may not show which paragraphs they modify.
Workaround:
Search for "BGBl [year]" to find Federal Law Gazette entries
Look for "Artikelgesetz" or amendment law names
Search effective dates like "2021-01-01 Inkrafttreten"
Problem: Only current versions easily accessible through ELI identifiers.
Workaround: Search Federal Law Gazette references for specific dates.
Citations not appearing: Some models ignore citation instructions despite clear guidance in MCP response. This is a model limitation, not server issue.
Solution: Use agent configuration with explicit citation requirements or consider multi-agent architecture.
✅ HTML URLs for Users
Returns clickable HTML links instead of JSON API URLs
Users can now read laws in browsers
Both HTML and JSON URLs provided
✅ German Compound Word Handling
Decomposes "Mieterhöhungsantrag" → "Mieterhöhung"
Removes suffixes: -antrag, -verfahren, -klage, -gesetz, -verordnung
Special handling for common legal terms
✅ Fallback Search
Never returns zero results for valid queries
Searches with original query if no legal references found
Provides helpful suggestions when nothing found
✅ Type Coercion
Handles models passing "10" (string) instead of 10 (number)
Schema validation now works with GLM-4.6 and similar models
✅ Model-Agnostic Instructions
Removed Claude-specific language

Scored across 5 tools
Each tool has a clearly distinct purpose with minimal overlap. intelligente_rechtssuche is the primary search for both legislation and case law, while deutsche_gesetze_suchen and rechtsprechung_suchen are specialized for legislation-only and case-law-only searches respectively. gesetz_per_abkuerzung_abrufen provides direct abbreviation lookup, and dokument_details_abrufen handles document retrieval. The descriptions explicitly guide when to use each tool, preventing confusion.
Naming is inconsistent with mixed conventions. intelligente_rechtssuche uses snake_case, but gesetz_per_abkuerzung_abrufen mixes snake_case with German words and abbreviations. deutsche_gesetze_suchen and rechtsprechung_suchen follow snake_case, while dokument_details_abrufen uses a different verb style (abrufen vs suchen). There's no uniform pattern across all tools, making them less predictable.
Five tools is well-scoped for a legal information server. It covers the core workflows: primary search, specialized searches, direct lookup, and document retrieval. Each tool serves a specific function without redundancy, and the count is manageable for agents to understand and use effectively.
The tool set covers the domain comprehensively with minor gaps. It supports search (both general and specialized), direct lookup, and document retrieval for German legal information. However, there's no explicit tool for browsing or listing laws/cases by metadata (e.g., by date or court without a search term), which could be a minor limitation for some agent workflows.
