StackData is a Model Context Protocol (MCP) server: Official statistics, China censuses & yearbooks, and as-of customs tariffs with legal citations. 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://api.stackdata.io/mcp and you're connected, with nothing to install locally. The current release is v0.1.0.
You'll find StackData 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.
