# InvoiceHub

> One JSON invoice model in. Any EU e-invoice format out. Pre-validated
> against the official EN 16931 (CEN) Schematron — via a single REST call,
> or a hosted MCP server for AI agents.

InvoiceHub validates, generates, and converts EU e-invoices across UBL 2.1,
UN/CEFACT CII, XRechnung 3.0 (Germany's mandatory B2G format), and Factur-X
(France/Germany hybrid PDF/A-3), all through a shared canonical model, using
the official CEN EN 16931 Schematron (v1.3.16) and KoSIT's official XRechnung
validator rules — the same artifacts tax authorities and Peppol access points
use. Generated and converted documents are self-validated before they are
ever returned; a document that would fail is never handed back silently.

## REST API

- Validate: `POST https://api.invoicehub.dev/api/v1/validate` (Bearer API key)
- Generate: `POST https://api.invoicehub.dev/api/v1/generate` (structured JSON → any format)
- Convert: `POST https://api.invoicehub.dev/api/v1/convert` (any supported format → any other)
- Try validation without a key: `POST https://api.invoicehub.dev/api/v1/playground`
- Format catalogue (live): `GET https://api.invoicehub.dev/api/v1/formats`
- OpenAPI spec: https://api.invoicehub.dev/api/v1/openapi.json
- Docs: https://invoicehub.dev/docs

## MCP server (no install, no auth for validation/generation)

A hosted Streamable HTTP MCP server at `https://api.invoicehub.dev/mcp`.
Manifest: https://invoicehub.dev/.well-known/mcp/server.json

- `validate_invoice` — validate a UBL 2.1 invoice/credit note XML string
- `generate_invoice` — generate an EN 16931-conformant UBL 2.1 invoice from structured fields
- `convert_invoice` — convert between UBL 2.1, UN/CEFACT CII, XRechnung 3.0, and Factur-X
- `list_supported_formats` — the live format catalogue (same source as GET /api/v1/formats)

`convert_invoice` targets beyond plain UBL_2.1 require an API key on the Pro
plan or above — see https://invoicehub.dev/pricing. Validation and UBL
generation remain free and unauthenticated over MCP.

Add it as a custom connector in claude.ai/Claude Desktop, or point any
MCP client at the URL directly:

```json
{ "mcpServers": { "invoicehub": { "url": "https://api.invoicehub.dev/mcp" } } }
```
