Connect an AI assistant

AddonNordic runs an MCP server so ChatGPT, Claude and other AI assistants can look up companies, run KYB, validate VAT numbers and screen sanctions on your behalf — using your own AddonNordic account.

MCP server URL
https://addonnordic.com/mcp

You'll paste this URL into your AI assistant's connector settings. You'll be asked to sign in to your AddonNordic account the first time you connect.
