MCP Server

Overview

The Website Data MCP server allows AI assistants to access Website Data directly through the Model Context Protocol (MCP). Once connected, you can ask your AI assistant questions about domains and technologies and it will query Website Data to provide answers.

The MCP server is available to all customers with API access. Claude Desktop and ChatGPT Desktop authenticate through your browser. Other clients may require a Website Data API key, which you can find on your Account page.

Setup

The Website Data MCP server is a remote server hosted at https://websitedata.app/mcp. No installation is required — simply configure your AI client to connect to the server with your API key.

Claude Code (CLI)

Run the following command in your terminal, replacing YOUR_API_KEY with your Website Data API key:

claude mcp add -t http websitedata https://websitedata.app/mcp -H "Authorization: Bearer YOUR_API_KEY"

You can verify the server was added by running claude mcp list. For more details, see the Claude Code MCP documentation.

Privacy & Security

All MCP requests use HTTPS. Your API key is passed as a Bearer token and is required on every request. The MCP server is read-only — it can search and retrieve data but cannot modify anything in your account. See our Privacy Policy for details on how we handle data.
