sci-host-mcp
Provides integration with arXiv for retrieving scientific papers, enabling literature search and data collection as part of the materials discovery workflow.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@sci-host-mcpinvestigate thermoelectric materials waste heat recovery"
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.
SciHost — 科学方向探索宿主系统
面向材料科学文献调研与可证伪假设生成的持续运行系统。输入文献语料,输出可证的科研发现、研究方向与含完整溯源链的发现报告。
本项目为比赛提交包,自包含、零外部服务依赖、离线可运行(无需任何 API Key)。
核心能力
科学文献采集与隐性配对:从论文语料发现跨领域隐性关联
CSP 知识抽取:自动抽取 组分-结构-性能 三元组
可证伪假设生成:生成含数值预测的假设(如"预测 X 材料带隙为 Y eV")
数字孪生仿真试错:内置
ResearchTwin虚拟实验环境,算法算子交叉验证 + 材料物理约束检查材料性能找全(内置 DSR-MO 算法):将已知材料性能数据映射为连续性能景观,用内置多模态优化算法一次性找全所有性能最优的候选材料,并为数值预测假设对标打分
验证复现与发现认证:扰动重跑 + 交叉验证 → 认证为科学发现
文献溯源链:每条发现可追溯到 假设 → 配对 → 论文 → CSP
EWC 持续学习:保护已验证知识,校准算子权重
Related MCP server: OPTIMADE MCP Server
内置核心算法:DSR-MO
本系统内置了 DSR-MO(小生境 / 群体智能方向的多模态优化算法),作为宿主系统中的一个研究算子,随项目一并提供。
算法定位:面向多模态优化的单目标 niching 算法,能够在一个连续函数空间内同时定位出所有等高的性能峰("先占地盘、后精耕细作":maximin 选择铺开占位保覆盖,Nelder-Mead 局部精修保精度,报告期密度过滤去冗余)。
本项目中的应用场景:数字孪生中的「材料性能找全」算子。把已知材料成分-结构-性能(CSP)数据构造成连续性能景观,DSR-MO 在该景观上一次找全所有性能极值的候选材料,作为可证伪假设的对照基准与打分依据。
算法源码仓库:https://github.com/aceris-sola/DSR-MO (评审可对照查看算法完整实现)
移植说明:为便于离线运行,算法以纯 numpy 实现并嵌入本包(
sci_host/dsr_mo/),不依赖 MATLAB/Octave。这是同一算法在本系统的实际应用形态。
快速开始
# 1. 安装依赖
pip install -r requirements.txt
# 2. 离线演示(默认,几轮快速跑)
python run.py
# 3. 材料科学完整流水线演示(推荐先跑这个,看完整效果)
python demo.py
# 4. 作为 MCP 服务使用(stdio 模式,供 Claude Desktop / Cursor / IDE 调用)
python run.py --mcp
# 5. 作为 MCP 服务使用(HTTP 模式,远程访问)
python run.py --mcp --http 8080启用 Sciverse 联网检索(真实文献 + 后端联网审查)
默认离线即用(内置语料,无需任何 Key)。需要检索真实文献或做后端联网审查时,配置一个 Sciverse API Key 即可,采集会自动走 https://api.sciverse.space/agentic-search(4.65 亿学术元数据)。
Key 填在哪(二选一):
推荐:复制
.env.example为.env,在SCIVERSE_API_TOKEN=后填真实 token(项目启动自动读取,.env已被 git 忽略)或用环境变量:
export SCIVERSE_API_TOKEN=sci_你的token
联网审查三步走:
python run.py --mcp # ① 启动 MCP 服务② 调用 sci_create_sciverse_host 创建联网宿主(联网开关)
③ 依次调用 sci_stream_crawl → pair → hypothesize → trial → verify,
每步读取真实中间结果,用 sci_stream_feedback 实时把关完整步骤、可复制的提示词见 USAGE.md 第 5 节。
