Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name
InvoicehubCommand (node, npx, python, etc.)Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.
- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
Follow the repository README to install the server and add its MCP configuration to your client.
validate_invoice
Validate an EU e-invoice XML string against the official EN 16931 Schematron. Accepts either syntax — UBL 2.1 (Invoice or CreditNote) or UN/CEFACT CII — and auto-detects which. A document declaring the XRechnung 3.0 CustomizationID is additionally checked against KoSIT's XRechnung delta ruleset. Returns whether it is valid and any failing BR-* / BR-DE-* business rules.
generate_invoice
Generate an EN 16931-conformant UBL 2.1 invoice from structured fields. The result is self-validated before being returned. Provide seller, buyer, and at least one line; for standard-rated (category "S") lines include a vatRate and the seller vatId.
convert_invoice
Convert an e-invoice between formats via the shared EN 16931 canonical model: parse the source document, re-serialize as the target, and validate the result before returning it — never a document that has not been checked. Format ids: "UBL_2.1" (OASIS UBL, the universal Peppol/EN16931 baseline), "UN_CEFACT_CII" (UN/CEFACT Cross Industry Invoice, required syntax for Chorus Pro/France and many ERP back-ends), "XRechnung_UBL" / "XRechnung_CII" (Germany's mandatory B2G format, XRechnung 3.0 — required for invoicing German public-sector buyers), "Factur-X" (France/Germany hybrid PDF+XML — a human-readable PDF/A-3 with the structured invoice embedded, common for French B2B). Binary formats (Factur-X) are base64 in both directions. Requires an API key on the Pro plan or above for any target beyond plain UBL_2.1 — call list_supported_formats to see current availability.
list_supported_formats
List the e-invoice formats InvoiceHub validates today and what is on the roadmap.

Registry/plugin listing metadata for InvoiceHub's hosted
MCP server. There's no local package here — the server itself is a hosted
Streamable HTTP endpoint at https://api.invoicehub.dev/mcp, implemented in the
main einvoice-dev1/einvoice monorepo
(packages/api/src/mcp.ts). This repo exists to give that endpoint a public
server.json and Claude Code plugin manifest, since MCP registries and the
plugin marketplace require a public repository to list against.
What it does
- validate_invoice — validate a UBL 2.1 invoice/credit note XML string against
the official EN 16931 Schematron (v1.3.16), returning any failing BR-*
business rules
- generate_invoice — generate an EN 16931-conformant UBL 2.1 invoice from
structured fields, self-validated before it's returned
- list_supported_formats — formats supported today vs. on the roadmap
No install, no API key — the endpoint is public and every tool is read-only or
self-validating.
