Set up
In ~/.cursor/mcp.json (all projects) or .cursor/mcp.json in the project:
{
"mcpServers": {
"indizio": {
"url": "https://indizio.rexago.com/mcp",
"headers": {
"X-Api-Key": "${env:INDIZIO_API_KEY}"
}
}
}
}
Keep the key itself in the environment variable INDIZIO_API_KEY — that
way it neither ends up in the project nor accidentally in version control.
Check
In Cursor's settings under MCP, "indizio" should appear with its tools. Then simply ask in agent mode, for example "Resolve the domain goldbachkirchner.de to a company".
