Common questions

Is DutyKit safe?

It passed 3 of 3 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?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.1) reached the registry today.

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?

DutyKit

EU business duties for AI agents. A remote MCP server that tells an agent which business rules apply in Germany, Luxembourg and the EU, with the legal source for every line, and lets it pre-check an invoice, a marketing message or a call before it acts.

Endpoint: https://dutykit.dev/mcp (Streamable HTTP, public beta, free, no account, 200 tool calls per day per IP, no inputs stored) Docs: https://dutykit.dev · https://dutykit.dev/llms.txt · Guides

Connect

Claude Code:

claude mcp add --transport http dutykit https://dutykit.dev/mcp

Any MCP client (JSON config):

{ "mcpServers": { "dutykit": { "type": "http", "url": "https://dutykit.dev/mcp" } } }

Tools

Tool	What it does
`pflichten(land, taetigkeit)`	Obligations for `DE` or `LU` plus EU-wide, filtered by activity: `website`, `online_handel`, `rechnung`, `werbung`, `ki_kontakt`, `gruendung`
`rechnung_vorpruefen(rechnung, land="DE")`	Missing mandatory invoice fields under § 14 (4) UStG
`werbung_vorpruefen(kanal, empfaenger, einwilligung_belegt, bestandskunde)`	May the agent send this marketing email or make this call? (§ 7 UWG)
`ki_hinweis(firma, sprache)`	AI disclosure wording under AI Act Art. 50(1) in `de`, `fr`, `en`, `lb`
`vat_pruefen(ust_id)`	Live EU VAT ID check via the European Commission's VIES service

Every check also returns a nachweis (timestamp, tool, responsible person, SHA-256 of the result) for the human who is liable.

Example prompts

"Before you publish the shop page: what does a website for a business in Luxembourg need?"
"Check this invoice for missing mandatory fields before you send it."
"May you send this newsletter to consumers who never opted in?"
"Start every call with the AI disclosure sentence in French for Muster S.à r.l."
