GreenCalculus
GreenCalculus MCP 服务器
作为来源可溯的温室气体排放因子和可审计追踪的碳计算,以 MCP 服务器形式提供。每个返回值都带有其精确的来源单元格和固定的数据版本——因此智能体返回的数字,人可以引用,机器可以复现,而不是一个猜测。
你需要这个包吗?
大概率不需要。服务器是远程的,如果你的客户端支持远程 MCP,直接指向 URL 即可——无需安装,无需更新:
{
"mcpServers": {
"greencalculus": {
"url": "https://mcp.greencalculus.com",
"headers": { "Authorization": "Bearer YOUR_KEY" }
}
}
}此包是为那些只能启动本地 stdio 进程的客户端,以及 docker run 安装而准备的。它是一个轻量桥接:将每条 JSON-RPC 消息转发到远程服务器,并原样返回回复。没有对任何方法做特殊处理,因此新工具无需发布即可在此出现。

通过 stdio 使用
{
"mcpServers": {
"greencalculus": {
"command": "npx",
"args": ["-y", "greencalculus-mcp"],
"env": { "GREENCALCULUS_API_KEY": "YOUR_KEY" }
}
}
}或者使用 Docker——-i 是必需的,-t 必须省略,因为容器的 stdin/stdout 就是传输通道,TTY 会破坏流:
{
"mcpServers": {
"greencalculus": {
"command": "docker",
"args": ["run", "-i", "--rm", "-e", "GREENCALCULUS_API_KEY", "greencalculus/mcp"],
"env": { "GREENCALCULUS_API_KEY": "YOUR_KEY" }
}
}
}在 https://greencalculus.com/developers 免费获取密钥——无需信用卡。发现(initialize、tools/list)无需密钥即可工作;调用工具则需要密钥。
工具
工具 | 功能 |
| 按键获取一个排放因子,附带其来源和版本 |
| 按自由文本搜索因子库 |
| 将杂乱的真实世界描述映射到最匹配的因子 |
| 说明因子为何不存在,而不是返回空结果 |
| 活动 → 排放量,包含单位换算和 GHG Protocol 范围 |
| 基于位置和基于市场的电力 |
| 隐含碳(EN 15978),明确说明缺失的生命周期阶段 |
| PCAF 融资排放,包含审计追踪 |
| 按运输方式、距离和载重计算的货运量 |
| 基于支出的 EEIO |
| 跨方式的商务出行 |
配置
变量 | 默认值 | 含义 |
| — | 你的 API 密钥。 |
|
| 覆盖端点。 |
|
| 每次请求的超时时间。 |
诊断信息写入 stderr。除了 JSON-RPC 之外,stdout 上不会写入任何内容——一个多余的字节都会破坏会话。
开发
npm test # unit tests, no network
node bin/greencalculus-mcp.js # reads JSON-RPC on stdin
