Invoice Intelligence MCP Server

We need to translate the given English text into Japanese. The text describes a paid MCP server for invoice processing. It mentions three tools: extract structured data, validate, and classify. Pricing details and payment method. No API key required. We must preserve product names, protocol names, URLs, numbers, technical terms. The name "Invoice Intelligence" is not in the text, so we don't include it. The text itself does not contain the name. So just translate the description. Key points: "paid MCP server" -> 有料のMCPサーバー. "invoice processing" -> 請求書処理. "Three tools" -> 3つのツール. "extract structured data from any invoice (pasted text, URL, or PDF)" -> 任意の請求書（貼り付けたテキスト、URL、PDF）から構造化データを抽出. "validate the extracted invoice for completeness and mathematical accuracy" -> 抽出された請求書の完全性と計算の正確性を検証. "classify the expense into an accounting
