Chem CP MCP Server

An MCP App that renders interactive 2D molecular structure diagrams from SMILES notation using RDKit.js. Ask your AI assistant to show you any molecule, and ChemCP displays the structure with computed properties - right inside the chat. It runs locally over stdio via the published package.

People connecting this server to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.
