ChemDraw MCP

An open-source MCP server that allows agents to generate publication-ready 2D chemical structures, reaction schemes, mechanisms, and spectra from names or SMILES. It renders outputs offline using RDKit and matplotlib, supporting interactive panels for 3D models and PubChem data sheets without requiring API keys or licenses.
