Loops: causal loop diagrams

Overview

Loops is a Model Context Protocol server that lets you create and edit causal loop diagrams directly in your chat. Draw complex system diagrams, share them on a linked canvas, and iterate collaboratively without switching between applications. Your AI assistant can call diagram tools natively through MCP instead of requiring manual copy-paste workflows.

Loops runs as a remote hosted service at https://loops.thijsmorlion.com/mcp with no local installation needed. Simply point your MCP client to the endpoint and start diagramming. No authentication is required. The service is currently at v1.0.0.

Loops belongs in the Design category on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, claim your listing to verify ownership and keep information up to date.
