chemdraw-mcp

chemdraw-mcp is an MCP server that lets Claude draw chemistry: structures, reaction schemes, mechanisms, spectra, TLC plates and pH curves, rendered locally with RDKit and matplotlib as PNG and SVG files. Each drawing also opens an interactive panel in the chat — hover a functional group, switch to the PubChem data sheet, rotate a 3D model, export or add an Anki card. It is free and open source (Apache-2.0) and needs no API key, no sign-up and no ChemDraw licence.

"Draw aspirin" in Claude Desktop. Demo edited to shorten the PubChem loading wait.

Without	With chemdraw-mcp
Claude describes a structure in words or writes SMILES you paste elsewhere	the structure appears in the chat, as files ready for a report
figures drawn by hand in ChemDraw or ChemSketch	one sentence per figure, one style across the whole report
molar mass, CAS number and hazards from three websites	one data sheet from PubChem, or one value as text
a pH worked out with an approximation you cannot check	the exact value with the textbook approximation beside it

Quick start

[Download the Claude Desktop extension](https://github.com/jurimaxam-dotcom/chemdraw-mcp/releases/latest) (chemdraw-mcp- .mcpb), double-click it and confirm in Claude Desktop.
Open a new chat and say *"Use the ChemDraw MCP: draw caffeine"*.
Try a prompt from the tool table below.

Other ways in (PyPI, cloning the repository, editing the config by hand) are under Installation.

Tools

The default profile registers 16 tools in five areas. Each description says which neighbouring tool to use instead, so the model can tell a drawing from a lookup from a calculation. Files go to ~/ChemDraw-Output/.

Area	Tool	Example prompt	Panel
Draw	`generate_molecule`	"Draw caffeine"	yes
	`batch_generate`	"Draw aspirin, caffeine and paracetamol, each as its own file"	yes
	`compare_molecules`	"What is the difference between ibuprofen and naproxen?"	yes
	`generate_reaction`	"Draw the esterification of acetic acid with ethanol as a reaction equation"	yes
	`generate_mechanism`	"Show me the SN2 mechanism step by step"	yes
	`generate_3d`	"Show methane as a rotatable 3D model"	yes
Lab graphics	`generate_spectrum`	"Draw the IR spectrum of aspirin"	yes
	`generate_tlc`	"TLC of my esterification: educt at Rf 0.3, product at 0.65, co-spot shows both"	yes
	`generate_titration_curve`	"Which indicator fits the titration of phosphoric acid with NaOH? Show me the curve."	yes
	`generate_species_distribution`	"Draw the species distribution of phosphoric acid over the whole pH range"	yes
Look up	`lookup`	"What is the CAS number of paracetamol?"	text
	`lookup_molecule_data`	"Give me a data sheet for ibuprofen"	yes
	`predict_spectrum`	"Which IR bands should aspirin show?"	text
Calculate	`calculate_ph`	"What is the pH of 0.1 M acetic acid, pKa 4.76?"	text
Anki	`export_anki_deck`	"I have an exam on NSAIDs on Friday and need to know the structures"	—

The 16th tool, save_png, is the server half of the panel's export button. It runs when you click that button and is never called by the model on its own.

What each tool does in detail, the options on the drawing tools (formats, render_style, abbreviate_groups, annotate_stereo) and the known limits: docs/tools.md.

Installation

Pick one route — installing twice registers the server twice and the model sees every tool doubled. Afterwards restart Claude Desktop and ask *"draw caffeine"*.

Claude Desktop extension (macOS, Linux): download chemdraw-mcp- .mcpb from the latest release, double-click it, confirm, restart Claude Desktop once. The first start fetches about 40 MB from PyPI, checked against pinned hashes; later starts are offline.
From PyPI (needs uv):

  uv tool install chemdraw-mcp

chemdraw-install

Cloning the repository, editing the config by hand, optional extras (Java for offline IUPAC names, AnkiConnect) and the full profile with 23 tools: docs/installation.md and docs/tools.md#profiles.

Something not working? uvx --from chemdraw-mcp chemdraw-doctor checks the installation and prints the fix for each problem.

Development

Architecture, setup and the test gate: docs/development.md.

Feedback, bugs and wishes

Something broke? Open a bug report — the form asks for the output of chemdraw-doctor.
Missing something in your course? Tell us what you would draw or calculate — the subject and the exam question help more than a feature name.
Wrong chemistry? Use the bug form and name the compound and the figure.
A question, or something you made with it? Discussions.
It worked for you? A ⭐ on the repository helps other students find it.
