Uae Einvoice MCP Server

uae-einvoice-mcp

MCP server for UAE e-invoicing / PINT AE — TRN/TIN validation, structural compliance, the 51-field mandatory checklist, UBL XML stub generation, and mandate timeline helpers.

Built with the MCP TypeScript SDK v2 (@modelcontextprotocol/server) over stdio. Free to run locally; no API keys required for v0.2.

Informational tooling only — not legal or tax advice, and not a substitute for Accredited Service Provider (ASP) XSD validation, digital signatures, or live FTA register checks. validate_pint_ae_xml runs the official OpenPeppol PINT AE 1.0.4 Schematron.

Why this exists

UAE e-invoicing (Peppol + PINT AE) forces ERP and finance teams to get dozens of mandatory fields, TIN vs TRN, and Peppol endpoint IDs right before an ASP will transmit anything. This server gives AI assistants a small, installable toolkit for those checks.

Tools

Requirements

• Node.js 20+

Install / run

npm install
npm run build
npm start

Dev (TypeScript directly):

npm run dev

Self-check (no MCP client needed):

Suggested test flow

1. check_pint_ae_fields with examples/compliant-invoice.json
2. generate_pint_ae_xml with the same payload (strict: true should succeed)
3. validate_pint_ae_xml on the generated XML (first call downloads PINT AE 1.0.4 rules)
4. Repeat 1–2 with examples/credit-note.json and examples/usd-invoice.json
5. generate_pint_ae_xml with examples/broken-invoice.json and strict: true (should refuse)
6. check_einvoicing_scope with transactionKind: b2b and an annual revenue

Roadmap

• 51-field checklist + PINT AE XML stub generation
• Official PINT AE 1.0.4 Schematron validation (validate_pint_ae_xml)
• Per-transaction scope helper (check_einvoicing_scope)
• Credit-note and non-AED fixtures + CI self-check
• Optional HTTP + API-key transport for hosted / paid tier
• Publish to npm (uae-einvoice-mcp@0.2.2)
• List in MCP registry (io.github.mirzaabubakr/uae-einvoice-mcp)
