Provides n8n community nodes that bring ETL-D's data parsing and enrichment capabilities into n8n workflows.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@ETL-D MCP Server Parse this bank statement into JSON"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
ETL-D is a deterministic data middleware designed to act as a shield for AI Agents. It stops LLMs from "hallucinating" over structured data by providing a strict, 3-layer parsing architecture via the Model Context Protocol (MCP).
Standard LLMs are terrible at reading raw B2B files (CSV, PDF, EDI, Norma 43). They suffer from:
Token Exhaustion: Sending a 5,000-row CSV to context is a waste of money.
Precision Loss: LLMs struggle with spatial alignment. A misplaced comma in a bank statement is a financial catastrophe.
Non-Determinism: You can't build a reliable pipeline if the output format depends on the LLM's "mood."

The ETL-D engine processes every request through a strict hierarchy:
Layer 1 (Heuristic): 100% Python-native deterministic parsers. 0% Hallucination risk. ~70ms latency.
Layer 2 (Semantic): Column-to-Schema alignment using embedding-based routing.
Layer 3 (LLM Shield): Strict JSON enforcement using Llama 3.3 70B with additionalProperties: false constraints for high-entropy noise.

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.
