Frequently asked questions
Is MockFox free?
Yes. No sign-up, no API key. Fair-use rate limits keep it fast for everyone, and clearly labeled sponsors pay for the servers.
What is MCP?
The Model Context Protocol is an open standard that lets AI assistants call external tools. An MCP server exposes tools; clients like Claude Desktop, Claude Code and Cursor call them.
Do I need an API key?
No. The MockFox MCP server is public and uses the same fair-use limits as the website.
