Welt

Overview

Welt is a Model Context Protocol server that brings tabular, causal, and forecasting models directly into your AI workflow. Connect your data to Welt's analytics capabilities and let Claude, Cursor, or any MCP client call these models as native tools without switching between applications.

Welt runs as a hosted service at https://welt.ergodic.dev/mcp, requiring only OAuth authentication to get started. There's nothing to install locally — your MCP client connects remotely to the endpoint. The latest release is v1.0.0.

Welt appears in the AI & Agents category on mcp.site and works with all major MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain Welt, claim this listing to verify ownership and keep information up to date.
