ETL-D MCP Server
ETL-D MCP 服务器 🌊
ETL-D 是一种确定性数据中间件,旨在充当 AI 代理的防护盾。它通过模型上下文协议(MCP)提供严格的 3 层解析架构,阻止 LLM 在结构化数据上“产生幻觉”。
⚠️ 问题:“数据税”与幻觉
标准 LLM 在读取原始 B2B 文件(CSV、PDF、EDI、Norma 43)时表现糟糕。它们面临:
令牌耗尽: 将 5,000 行的 CSV 发送到上下文是浪费金钱。
精度损失: LLM 难以处理空间对齐。银行对账单中一个放错位置的逗号就是一场金融灾难。
非确定性: 如果输出格式取决于 LLM 的“心情”,你就无法构建可靠的管道。

✅ 解决方案:3 层瀑布架构
ETL-D 引擎通过严格的层级处理每个请求:
第 1 层(启发式): 100% Python 原生确定性解析器。0% 幻觉风险。延迟约 70 毫秒。
第 2 层(语义): 使用基于嵌入的路由进行列到模式的对齐。
第 3 层(LLM 防护盾): 使用 Llama 3.3 70B 并带有
additionalProperties: false约束来强制执行严格的 JSON,以处理高熵噪声。
🚀 快速开始(Claude Desktop)
打开你的
claude_desktop_config.json。添加 ETL-D 服务器(确保使用版本
3.3.3):
{
"mcpServers": {
"etld": {
"command": "npx",
"args": [
"-y",
"@pablixnieto2/etld-mcp-server@3.3.3"
],
"env": {
"ETLD_API_KEY": "YOUR_API_KEY_HERE"
}
}
}
}🔑 如何获取 API 密钥?
选项 A: 手动购买(人工) 在 api.etl-d.net 获取入门包(5 美元 / 5,000 积分)或订阅。
选项 B: 零接触配置(代理主导)🤖 如果你没有密钥,只需询问 Claude:“我没有 ETL-D 密钥,你能帮我获取一个吗?”。 代理将调用 /provision 工具,为你生成 Stripe Checkout 链接,并在支付后自动设置密钥。零接触,人在环中。
🛠️ 可用的 MCP 工具

TDQS
Scored across 37 tools
Many tools have overlapping purposes. For example, enrich_single can do what specific enrich_* tools do, match_endpoint and dedupe_items both perform fuzzy matching, generate_sepa and download_sepa are near-identical, and pipeline tools duplicate individual enrich operations. This ambiguity increases the risk of agents selecting the wrong tool.
Names follow a standard suffix pattern (_v1_..._post), but prefixes vary inconsistently: some use 'enrich_', others 'parse_', 'extract_', 'generate_', 'download_', and a few have 'endpoint' or 'system' inserted. While the overall structure is recognizable, the inconsistency in action verbs and qualifiers makes it less predictable than it could be.
With 37 tools, the count is too high for the server's scope. Many tools could be consolidated (e.g., all enrich_* into one parameterized tool, SEPA generation and download into one). This adds unnecessary complexity and cognitive load, making the toolset feel bloated rather than well-scoped.
The server covers many data enrichment and parsing tasks, but several practical gaps remain. Notably, create_batch_task returns a task_id with no polling/status tool to retrieve results, and there is no generic CSV parser or credit balance checker. These missing operations will hinder agent workflows that require batch processing or account monitoring.
