MCP clients
Register lookup Beta lets an MCP client look up CVR, Retsinformation, Statistics Denmark and Folketinget. The client connects to https://mcp.komplai.dk/mcp over Streamable HTTP and sends your personal API key as a Bearer header on every request. Register lookup describes the tools.
Before you start
- Your organisation's agreement includes Register lookup, and an administrator has given you access to it.
- API access to Register lookup is turned on for your account, so you can create a key with
mcp:read. If it is not, Register lookup in the hub says so. - Register lookup is approved for test data only.
Create a key
- In the hub, open Register lookup (
/modules/mcp). The page shows the address and the configuration for your environment. - Choose Create a key for Register lookup. It opens API keys with Register lookup chosen.
- Name the key, for example after the client and the computer, and choose how long it lasts.
- Under Review access, check that
mcp:readis selected and choose Create API key. - Copy the key. It is shown only once.
The key starts with kp_live_ and is bound to you and your organisation. It reaches only what you have access to.
Connect VS Code
- In VS Code, run MCP: Open User Configuration from the Command Palette.
- Merge the configuration below into your existing settings.
- Start the server
komplai. VS Code asks for the key in a hidden field, so it never ends up in a file.
{
"inputs": [
{
"type": "promptString",
"id": "komplai-api-key",
"description": "komplai personal API key (mcp:read)",
"password": true
}
],
"servers": {
"komplai": {
"type": "http",
"url": "https://mcp.komplai.dk/mcp",
"headers": {
"Authorization": "Bearer ${input:komplai-api-key}"
}
}
}
}This is the configuration Register lookup in the hub generates. It contains no key. It works in VS Code's extension host, not in Agent Host sessions. See VS Code's MCP configuration reference.
Other clients
Another MCP client works if it supports Streamable HTTP and lets you send a fixed Authorization: Bearer header with your personal API key. Keys are never accepted in the URL. Keep the key out of shared configuration and command history: use the client's secret store or an environment variable.
To check your key and the connection without a client, start a session with initialize:
curl -i https://mcp.komplai.dk/mcp \
-H "Authorization: Bearer $KOMPLAI_TOKEN" \
-H "Content-Type: application/json" \
-H "Accept: application/json, text/event-stream" \
-d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-03-26","capabilities":{},"clientInfo":{"name":"connection-check","version":"1"}}}'A working key answers with the initialize result and an Mcp-Session-Id header. Without a key, the server answers 401 api_key_required. Set KOMPLAI_MCP_SESSION_ID to the Mcp-Session-Id from the response, and close the session again with the same key:
curl -X DELETE https://mcp.komplai.dk/mcp \
-H "Authorization: Bearer $KOMPLAI_TOKEN" \
-H "Mcp-Session-Id: $KOMPLAI_MCP_SESSION_ID" \
-H "MCP-Protocol-Version: 2025-03-26"Closing a session does not revoke the key.
Sessions and limits
- A session is bound to your organisation, to you and to the key. Another key, or a revoked one, cannot use it.
- A key can have 5 sessions at a time. A session ends after 30 minutes without activity.
- A request body can be at most 4 MiB.
- Access is checked again on every request and every tool call, so a revoked key, an expired key or a withdrawn assignment stops working at once.
- Lookups follow your account's request limits.
Pseudonymise text from the client
The client also lists tools to find personal data, pseudonymise text and put the originals back; they work only when the same key has redact:detect and you have access to Redact. They use regex only and do not find names.
Where data goes
- The lookup parameters go to the register you query.
- Register lookup runs on komplai's EU infrastructure in Germany.
- Lookups and regex use no AI, and they do not count towards AI usage or your organisation's monthly AI spending cap.
- komplai does not store the text, queries or lists of labels in the Audit log. Metadata about access and usage is recorded.
Revoke access
Revoke the key under API keys (/api-access) in the hub. The client's sessions stop working at once.
