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”。
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。

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。
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"
}
}
}
}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。
金融与 B2B 重活 parse_bank_statement：支持西班牙 Norma 43（N43）。将原始银行文件转换为干净的 JSON。
parse_trade_history：从复杂的券商导出中确定性提取交易、费用和股息。
parse_edi：ANSI X12 EDI 解析器（针对 850 采购订单优化）。
generate_sepa_xml：JSON 到 PAIN.008（直接借记）XML 生成器。
文档智能 pdf_to_spatial_markdown：对代理至关重要。在 LLM 读取之前，将 PDF 转换为保留表格结构的 Markdown。
extract_invoice / extract_resume：标准 B2B 文档的高精度模式提取。
原子增强（每次调用 1 积分） enrich_amount：将“总计：1.240,50€”清理为 {amount: 1240.50, currency: "EUR"}。
enrich_date：解析人类可读的日期（“下周五下午 5 点”），并具有时区感知。
enrich_address：将全球混乱的地址标准化为结构化组件。
accounting_map：将概念映射到西班牙 PGC、美国 GAAP 或 IFRS。
云引擎：托管在 api.etl-d.net（Python/FastAPI）。
Python SDK：pip install etld。
n8n 节点：在 n8n 社区中作为 n8n-nodes-etld 提供。

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.
