MCP server turns molecule names or SMILES into publication-style chemistry drawings
`chemdraw-mcp` is an open-source MCP server for Claude Desktop that converts molecule names or SMILES strings into publication-style 2D structure drawings, reaction schemes, and step-by-step mechanisms — fully offline via RDKit.
Score breakdown
The server brings offline, publication-quality chemical structure rendering and mechanism drawing into Claude Desktop's chat interface, removing the need for manual drawing tools for chemistry and pharmacy workflows.
- 01Converts molecule names or SMILES strings into publication-style 2D structure drawings (PNG/SVG)
- 02Rendering is fully offline via RDKit — no ChemDraw installation required
- 03Supports full reaction schemes and step-by-step curved-arrow mechanisms
`chemdraw-mcp`, published by JuriMx on GitHub, is an MCP server for Claude Desktop that bridges natural-language chemistry queries and publication-quality chemical graphics. Typing a molecule name or SMILES string — for example, "draw aspirin" — produces a print-ready PNG or SVG rendered fully offline through RDKit, with no ChemDraw installation required.
Beyond simple structure drawings, the server supports full reaction schemes, step-by-step curved-arrow mechanisms, schematic spectra, and an interactive preview panel rendered inline in the chat. An optional ChemDraw CDXML export format is available for users who prefer to continue editing in ChemDraw; the project notes it is unofficial and not affiliated with Revvity. The stated target audience is pharmacy and chemistry students who need structures, substance data sheets, and Ph.Eur. assay calculations accessible directly from a chat interface without manual drawing tools.
