How do I use labmate-mcp?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@labmate-mcp Find the most cited papers on copper-catalyzed C–H activation from the last 5 years" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

labmate-mcp is an MCP server that connects Claude to scientific databases, computational chemistry tools, bench references, and writing utilities. One install covers the entire research workflow.

🚀 Quick Start

pip install labmate-mcp

Then add this to your Claude config:

On macOS: ~/Library/Application Support/Claude/claude_desktop_config.json On Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "labmate": {
      "command": "labmate-mcp"
    }
  }
}

{
  "mcpServers": {
    "labmate": {
      "command": "labmate-mcp"
    }
  }
}

docker build -t labmate-mcp .
docker run -it labmate-mcp

Restart Claude. 61 of 81 tools work out of the box — no API keys needed.

TIP

Want retrosynthesis, pKa prediction, or NMR shifts? Runlabmate-mcp --setup to add free API keys.

💬 What Can I Do With This?

Just talk to Claude naturally:

"Find the most cited papers on copper-catalyzed C–H activation from the last 5 years"

Searches across multiple databases, ranks by citations, and gives you abstracts and AI-generated summaries.

"Suzuki coupling, 150 mg aryl bromide (MW 261), 5 mol% Pd(PPh₃)₄, 1.3 eq boronic acid, 2.5 eq K₂CO₃ — how much of everything?"

Calculates exact masses for each reagent with your substrate as the limiting reagent.

"I'm developing a new reaction. What should I be thinking about?"

Walks you through a structured reaction development checklist — covering everything from initial mechanistic hypotheses to scope exploration and scale-up.

"I need to protect a primary amine — stable to acid, cleavable by hydrogenation"

Compares protecting groups against a stability matrix and suggests the best match (here: Cbz).

"Format these DOIs as an ACS bibliography, then give me an experimental template for a Buchwald–Hartwig"

Generates a numbered reference list and a fill-in-the-blank procedure with suggested workup and safety notes.

Ask Claude…	What happens
"What are the NMR solvent peaks for DMSO-d₆?"	Residual ¹H: 2.50 ppm (quintet), ¹³C: 39.52 ppm, water: 3.33 ppm
"Generate 20 cyclic pentapeptides with some D-amino acids"	Returns SMILES with MW, logP, and TPSA for each
"I want to submit to JACS — what do I need to know?"	Word limits, abstract length, citation format, graphical abstract specs
"Retrosynthesis of ibuprofen"	Multi-step route back to commercial starting materials
"pKa of 4-nitrophenol?"	Quantum-chemistry prediction via Rowan Science
"Cooling bath for −42 °C?"	MeCN / dry ice, or chlorobenzene / dry ice

Aliases: S2_API_KEY, MP_API_KEY, RXN4CHEMISTRY_API_KEY also work.

If you prefer to configure keys manually, add them to your Claude config:

{
  "mcpServers": {
    "labmate": {
      "command": "labmate-mcp",
      "env": {
