Steel Brain
Steel Brain
一个为 AI 代理提供钢铁领域知识的 MCP 服务器 — 牌号属性、替代判定和钢厂证书指导,以 MCP 工具的形式提供,供你的代理调用。
也可通过 REST API 获取,访问 https://api.steelbrain.dev。
MCP 服务器
Steel Brain 是一个 Model Context Protocol 服务器。它通过 stdio 传输暴露三个 MCP 工具:
MCP 工具 | 功能 |
| 某钢牌号的属性、化学成分、形态、应用和可焊性。支持别名解析(4140 = 42CrMo4 = SCM440;S355 = ST52)。 |
| 给定 from_grade、to_grade、application,返回一个判定(valid / conditional / invalid),并说明一个牌号是否可以替代另一个牌号。 |
| 针对某牌号和用途,应使用哪种钢厂证书(EN 10204 3.1/3.2,船级社证书 ABS/DNV/LR/BV/NK),以及需要检查什么。 |
运行 MCP 服务器
pip install -r requirements.txt
python -m steel_brain.mcp_server通过 stdio 传输启动 MCP 服务器,可被任何 MCP 客户端使用(Claude Desktop、Claude Code 或任何兼容 MCP 的代理)。
MCP 客户端配置示例
{
"mcpServers": {
"steel-brain": {
"command": "python",
"args": ["-m", "steel_brain.mcp_server"]
}
}
}使用官方 MCP SDK(mcp 包)构建,通过标准 MCP 工具接口注册三个工具。

为什么选择 Steel Brain
大语言模型对钢铁只是猜测。它们会告诉你 4140 退火态可以替代 4140 预硬态,然后把活儿搞砸。Steel Brain 基于由一线钢材贸易商构建、经过人工验证的知识库来回答,宁可诚实地返回“不在知识库中”,也不给出有把握的猜测。
有价值的部分在于替代判定和证书逻辑:
4140RB 到 4140QT(退火态与预硬态):不可替代,相同合金,热处理状态相反
316L 到 304L 用于海洋环境:不可替代,耐腐蚀等级不同
EH36 到 S355 结构钢:单向有效,反向有条件
无缝管与 ERW 用于承压用途:永远不可互换
覆盖范围
覆盖碳钢、合金钢、不锈钢,共 23 个牌号。圆钢、空心棒材、板材、管材。39 条替代规则,4 份证书指南。
REST API(MCP 的替代方案)
同样的知识可通过 REST 获取,访问 https://api.steelbrain.dev:
curl "https://api.steelbrain.dev/v1/grade/4140QT" -H "X-API-Key: YOUR_KEY"
curl "https://api.steelbrain.dev/v1/substitution?from_grade=316L&to_grade=304L&application=machined" -H "X-API-Key: YOUR_KEY"上线时提供免费套餐。联系方式:dryow.jt@gmail.com
诚实设计
牌号属性:来自已发布标准(ASTM/EN/JIS/API/ABS)的范围,并明确标注。
替代与证书逻辑:经贸易验证、由一线贸易商出具的带日期判定。
未知牌号:诚实地返回“不在知识库中”,绝不编造。
