ChatGPT
Use VPNDetection in ChatGPT on the web: check IP addresses and look into our databases, signed in with your account.
ChatGPT can check IP addresses, look into any of our databases and tell you which ones your organization holds. It connects to our hosted MCP server, https://mcp.vpndetection.io/mcp, you sign in with your VPNDetection account, and every tool is read-only.
Add it to ChatGPT
In ChatGPT on the web, go to Plugins, click + and choose Add custom MCP server. Name it VPNDetection, enter https://mcp.vpndetection.io/mcp as the server URL and choose OAuth. If ChatGPT asks how to register, choose its Client ID Metadata Document: there's no client ID or secret to enter. Create it, install it, and when ChatGPT asks, sign in, pick which of your organization's API keys the connection uses, and approve. Your workspace's policies decide whether you can add a server, so if the option isn't there, ask your workspace admin.
Then type @ in a chat, pick VPNDetection and ask something like "Is 45.83.91.1 a VPN?".
Your API key
ChatGPT never sees the key. Our server uses it on your behalf, so every call counts against that key's plan. Approving needs permission to share your organization's API keys, and asks you to confirm it's you. You can disconnect it at any time from the console, under Settings > Sessions & devices > Connected applications; access ends within about a minute.
