Common questions

Is BGB (Germany) safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.9) reached the registry 24 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: GitHub, Desktop Commander, Cloudflare MCP

arxo-bgb.git

Pinned canon, executable as it stands: source text with provenance, the model built over it and the scenarios that check its answers. The norms here are data — they are executed by law; this repository carries no rule code of its own.

How it is verified

Every package is built by package.py with the pinned toolchain: compilation, §267 scenarios on both evaluators, replay of saved evaluations and a rebuild from the release itself. A failure of any step stops the build.

python3 tools/toolchain.py download --lock toolchain.lock.json --out /tmp/law-tools

python3 /tmp/law-tools/package.py packages/ \ --lawc /tmp/law-tools/law-cli --offline --out /tmp/ -release

Dependencies

Dependency bytes are pinned under packages/ /deps/ and verified against the contentHash recorded in law.lock: the build and the CI are offline.

Asking these packages

Two ways, the same slice of the canon and the same engine; the difference is whose machine evaluates.

Hosted: https://mcp.arxo.io/mcp/de-bgb — requests are evaluated on Arxo infrastructure.
Local: docker compose -f mcp/compose.yml up — nothing leaves the machine.

mcp/pin.json records what either one must answer from: the content hash of the canon profile, the pinned packages, the ABI version of the engine and the availability of the hosted endpoint. An answer that cannot be traced to that pin is not this repository's answer.

Worked cases

Each collection is a case package of its own: the facts, the questions and the answers, with the pinned canon as its dependency. Ask one from its directory with law ask . — nothing is downloaded.
