概览

AI 生成的概览

一个化学科研 MCP 服务器，提供 81 个工具，涵盖文献检索、化合物数据、逆合成、实验台计算与引文格式化。

可以做什么
  • 跨 Crossref、OpenAlex 与 Semantic Scholar 检索论文，追踪引用关系，查找作者档案、预印本与开放获取 PDF
  • 查询化合物、理化性质、安全数据、晶体结构、质谱、结合亲和力与蛋白质结构
  • 运行计算化学：逆合成、产物预测、原子映射、pKa、溶解度、ADMET 与 NMR 位移预测
  • 将肽序列转换为 SMILES、生成肽库、评估合成可行性并解析 MS/MS 离子
  • 使用实验台计算器与参考查询：摩尔浓度、反应投料量、命名反应、保护基、溶剂、后处理、显色剂、缓冲液与安全卡
  • 格式化引文与参考文献表，生成实验模板，查询期刊要求并准备补充材料清单
适用场景
适合化学研究者与学生，让助手在同一处协助文献综述、合成路线设计、反应开发、实验计算与论文写作准备。多数参考与计算工具无需任何配置即可使用。
运行要求
以 Python 包形式通过 pip 本地安装，由 Claude Desktop 或 Claude Code 配置以 stdio 启动。可选免费 API 密钥可解锁更多工具：ROWAN_API_KEY 用于 pKa、溶解度、ADMET 与 NMR 预测，RXN_API_KEY 用于逆合成与产物预测；另有 Semantic Scholar、Unpaywall、Materials Project、Web of Science 与 EPA CompTox 的可选密钥。密钥可保存在本地 env 文件或写入服务器配置。
安装前请注意
多个工具会把查询发送到第三方科学 API，检索词与结构信息会离开本机。可选密钥如 ROWAN_API_KEY、RXN_API_KEY、WOS_API_KEY、COMPTOX_API_KEY 存于本地 env 文件或配置中，需妥善保护。pKa、ADMET、NMR 与逆合成结果为模型预测，不能替代实验验证或安全评估。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Labmate Mcp，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Desktop only，通过 STDIO。 STDIO 服务会启动本地进程，因此需要 SourceWeft 桌面宿主。

其他 MCP 客户端

🚀 Quick Start

bash
pip install labmate-mcp

Then add this to your Claude config:

Claude Desktop  →  claude_desktop_config.json

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

json
{  "mcpServers": {    "labmate": {      "command": "labmate-mcp"    }  }}
Claude Code  →  .mcp.json in your project root
json
{  "mcpServers": {    "labmate": {      "command": "labmate-mcp"    }  }}
Docker
bash
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? Run labmate-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.

More things you can ask
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
