BGB (Germany) — Claude Code MCP server: features and setup
Ask about German Civil Code rules, including deadlines and periods, and get answers with grounds. Useful when examining a specific case against the BGB.
claude mcp add --transport http de-bgb https://mcp.arxo.io/mcp/de-bgbWhat BGB (Germany) does
The server answers questions using packages of BGB rules and provides grounds for its answers. The material covers periods, tenancy, inheritance, sales and other areas of civil law. Case packages include facts, questions and answers that can be used to examine particular scenarios.
You can send requests to the hosted server or run it locally with Docker Compose. Hosted requests are processed on Arxo infrastructure; the local option keeps them on the machine. That distinction matters when choosing where to evaluate a query. For Claude Code, connect through the HTTP command below; start the local option with docker compose -f mcp/compose.yml up.
What it helps with
- work out a legal period from case dates
- review a tenancy question under the BGB
- identify grounds for an answer
- match case facts to a BGB rules package
Example prompts for the agent
- Work out the period from these dates and give the legal grounds.
- Review this tenancy termination under the BGB.
- Check which inheritance rules apply to this case.
