Frequently asked questions

What is the Reexpress MCP server?

The Reexpress MCP server is an Data Engineering Model Context Protocol server that lets Claude Code, Cursor, Windsurf, VS Code with Copilot, and other MCP-compatible AI agents statistical verification for search and data science workflows. It exposes Reexpress's capabilities as tools the AI can call directly from your editor or CLI.

How do I install Reexpress MCP with Claude Code?

The fastest way is the MCPizy CLI: run `mcpizy install reexpress` and MCPizy will add the server to your `.claude.json` automatically. You can also install it manually by adding an entry under `mcpServers` in `.claude.json` with the command `npx -y @reexpress/mcp` and restarting Claude Code.

Is Reexpress MCP free?

Yes. The Reexpress MCP server is free and open source (see the GitHub repository linked on this page). You may still need a Reexpress account or API key to connect the server to the underlying service, but the MCP layer itself has no MCPizy subscription cost.

Does Reexpress MCP work with Cursor and Windsurf?

Yes. Any MCP-compatible client works — including Claude Code, Claude Desktop, Cursor (via `.cursor/mcp.json`), Windsurf, VS Code with Copilot Chat, and custom agents built on the MCP SDK. The same install command targets all of them; only the config file path differs.
