topper-mcp
Provides academic paper retrieval via the Semantic Scholar API, enabling searches for top-tier research papers and returning their metadata and links.
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., "@topper-mcpFind recent CCF-A papers on parameter-efficient fine-tuning of LLMs"
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.
用一段话描述你要找的研究,返回这个方向上的顶会顶刊论文。
它做了什么
一个研究问题
→ LLM 写检索简报 (query families + 领域自己的术语)
→ 多轮检索 (Semantic Scholar + OpenAlex,合并去重)
→ 档次门 (CCF / 中科院分区 / JCR / WoS / 旗舰刊名单)
→ 相关性门 (主题契合度,光有声望进不来)
→ 打分 + 全景 (学派、活跃团队)Related MCP server: Research MCP
安装
pip install "topper-mcp[mcp]" # 含 MCP 服务
pip install topper-mcp # 只要库和命令行(引擎零依赖,纯标准库)
cp .env.example .env # 只有两项必填,见下
topper doctor # 它会逐条告诉你还缺什么配置
必填两项,topper doctor 会检查并点名缺失的那一项。
变量 | 必填 | 说明 |
| 是 | 任何 OpenAI 兼容端点——OpenAI、本地 vLLM/Ollama 网关、中转都行 |
| 是 | 例如 |
| 否 | 默认 |
| 否 | 逗号分隔,主模型不可用时依次尝试 |
| 否 | 不填也能跑,但会被限流到几秒一次。免费申请 |
| 否 | OpenAlex 的礼貌策略;不填就走慢速公共池 |
| 否 | 档次表的位置,见 |
当 MCP 服务用

topper plan "双重差分 多期处理 异质性" # 只出检索计划,不打数据源
topper tiers "Journal of Econometrics"当库用

需要自己装
引擎能读,但这些名录各有使用条款,本仓不做再分发。放进 topper/data/(或
TOPPER_DATA_DIR 指向的目录)即可生效,格式见
topper/data/README.md。缺表不影响运行,topper doctor
会报告哪几张没装。
名录 | 学科数 | 等级 |
中科院分区 | 21 | 1–4 区 |
JCR | 254 | Q1–Q4 |
SCI / SSCI / A&HCI | — | 是否收录 |
FMS 经管期刊评级 | 33 | A/B/C/D/T1/T2 |
另外两件要知道的
只返回元数据和链接,不抓取付费全文。
一次检索是一次 LLM 调用加若干次数据源往返,通常 30–120 秒。检索简报会缓存到磁盘, 同一个问题再问一次快得多。
开发
pip install -e ".[dev,mcp]"
pytest -q许可
代码是 MIT。
两处例外:
名录数据保留各自的条款,见
topper/data/README.md品牌资产(
assets/目录、TOPPER 名称与标识)不在 MIT 授权范围内。代码随意 fork,请用你自己的名字和标识发布
