"Flat" matching MCP servers:

MCP server for ISO 20022 acmt.001 Account Opening (and companion acmt.* messages): message-type discovery, required-field lookup, JSON Schema introspection, IBAN/BIC/LEI validation, flat-record validation, and validated acmt XML generation.

Converts PDF, Word, PowerPoint, Excel, and HTML documents into Markdown, handling files up to 8 MB in a single call and routing larger or scanned files through an OCR and table-detection queue that returns Markdown plus a JSON structure file. Results arrive either by polling or a signed webhook.

It enables users to infer bounded flat CSV/JSON/JSONL schemas, propose and review correspondences to a target contract, validate records, and generate versioned mappings with reusable Python transforms through nine stdio tools.

Enables AI assistants like Claude Desktop, Claude Code, and Cursor to interact directly with Flatfile data through 100+ API endpoints for viewing, managing, and manipulating sheets, workbooks, records, and spaces.
