MCP server

rep4.eu in your AI assistant

A public Model Context Protocol (MCP) server. Assistants such as Claude and ChatGPT can use it to check whether a company established outside the EU needs a GDPR Article 27 EU representative, and to verify designations rep4.eu has issued. No account and no sign-in.

ChatGPT: https://api.rep4.eu/mcp/chatgpt (requirement check and verification only)

Streamable HTTP, stateless, no authentication. All tools are read-only.

Connect

Claude: Settings → Connectors → Add custom connector, then paste https://api.rep4.eu/mcp.
ChatGPT: add the rep4.eu app from the ChatGPT app directory once it is listed, or connect https://api.rep4.eu/mcp/chatgpt in developer mode.
Other MCP clients: add a remote server with the URL above and no authentication.

Data and privacy

The tools receive only the arguments listed above. They never ask for names, email addresses, conversation history or files.
Tool arguments are not stored. We count calls per tool and outcome (for example "Required" or "not found") without the arguments.
Technical request data (time, path, status) is processed by our hosting and network providers as described in the Privacy Policy.
The verification tool returns only what the public verification page already shows.

Not legal advice

The requirement check applies the Article 27 rule to the answers it is given. It is general information, not legal advice and not a legal determination for a specific company. Have the result confirmed by a lawyer or your data protection officer before relying on it. Our Article 27 guide explains the rule in full.
