invoicehub-mcp

Structured JSON errors mapped to the official BR-* business rules. No enterprise sales call required.

README

invoicehub-mcp

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.
