This is a deterministic parsing layer that sits between LLMs and messy B2B data formats. It exposes MCP tools for Spanish Norma 43 bank statements, ANSI X12 EDI purchase orders, SEPA XML generation, and PDF-to-markdown conversion with table preservation. The three-layer architecture routes requests through native Python parsers first, then semantic alignment, and only hits an LLM as a last resort with strict JSON schema enforcement. Also includes atomic enrichment tools for cleaning currency strings, resolving natural language dates with timezone awareness, and mapping accounting concepts to PGC, GAAP, or IFRS. Requires an API key from api.etl-d.net, which Claude can provision automatically via Stripe. Useful when you need guaranteed precision on financial documents or EDI flows where hallucinations break compliance.
