What io.github.jurimaxam-dotcom/chemdraw-mcp does

Chat → chemical structure. An MCP server for Claude Desktop that turns molecule names or SMILES into publication-style 2D structure drawings — "draw aspirin" produces a print-ready PNG/SVG, rendered fully offline with RDKit. No ChemDraw required; ChemDraw CDXML is available as an optional extra format for users who want to keep editing there.

CVE-2025-59288high · fixed

Playwright downloads and installs browsers without verifying the authenticity of the SSL certificate

### Summary Use of `curl` with the `-k` (or `--insecure`) flag in installer scripts allows attackers to deliver arbitrary executables via Man-in-the-Middle (MitM) attacks. This can lead to full system compromise, as the downloaded files are installed as privileged applications. ### Details The following scripts in the `microsoft/playwright` repository at commit [`bee11cbc28f24bd18e726163d0b9b1571b4f26a8`](https://github.com/microsoft/playwright/commit/bee11cbc28f24bd18e726163d0b9b1571b4f26a8) u

README

chemdraw-mcp

Chat → chemical structure. An MCP server for Claude Desktop: you describe a molecule, a reaction or a lab result in plain words, and it draws the figure — a print-ready PNG/SVG rendered locally with RDKit, plus an interactive preview inside the chat. "Draw aspirin" is already a complete command.

Built for pharmacy and chemistry students who spend too much time clicking hexagons. 20 tools cover what a report or a slide actually needs: structures, reaction schemes, step-by-step mechanisms, substrate-scope figures, TLC plates, titration curves, schematic spectra, substance data sheets, Ph.Eur. assay calculations and Anki decks.

What it costs you: one install command. Apache-2.0, no API key, no sign-up for the server, no ChemDraw licence — you need Claude Desktop and uv, everything else is fetched once. Rendering runs entirely on your machine; only name resolution and the database lookups reach the internet. ChemDraw CDXML is an optional extra format for people who want to keep editing there, never a requirement.

Example output

"Draw caffeine" — print-ready PNG, generated by generate_molecule:

"Show the Fischer esterification of ethanol with acetic acid" — generate_reaction renders the scheme with conditions above the arrow, live in the chat panel:

"Show the Fischer esterification mechanism step by step" — generate_mechanism renders curved electron-flow arrows in the interactive panel:

"Make a scope figure of my Suzuki couplings: 3a 92%, 3b 88% after 12 h, 3c 64% with ee 94% and dr 10:1, 3d 71%" — generate_scope_table sets the general equation with its conditions on top and the products below it, on a shared bond length and a shared caption baseline:

"Sketch the IR spectrum of ethyl acetate" — generate_spectrum (draws the peaks it is given, with per-type axis conventions):

"TLC of my esterification: educt at 0.30, product at 0.65, the co-spot shows both, some educt left" — generate_tlc draws the plate the lab report asks for, with mobile phase and detection as its caption:
