Citation Check is a Model Context Protocol (MCP) server: Does a cited URL exist, and does the source name what your claim names? Two answers. As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.
It's a hosted (remote) server — point your client at https://exmachina-ai.fly.dev/verify and you're connected, with nothing to install locally. The current release is v1.0.0.
You'll find Citation Check in the Development category here on mcp.site; it connects to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP client — see the install snippets below. If you maintain Citation Check for SecondStageTurbine, claim this listing to verify ownership, earn the Verified badge, and keep the details current.
