Norway Invoice MCP 🇳🇴 — How can my AI agent send a Peppol/EHF e-invoice in Norway?

Use it in 60 seconds

Paste this into your MCP client config (Claude Desktop, Cursor, Windsurf, or any MCP-capable agent):

{
  "mcpServers": {
    "norway-invoice": {
      "type": "http",
      "url": "https://inv-no.wishpool.app/mcp"
    }
  }
}

Nothing to install. Credentials, when you need them, travel as HTTP headers on each request and are never stored — see the threat model.

Or run it yourself

Would you rather not send production credentials to a server you do not control? Deploy this identical code to your own account and point your agent at your own URL:

git clone https://github.com/junter1989k-ai/norway-invoice-mcp && cd norway-invoice-mcp && npx vercel --prod

Remote MCP server that lets any AI agent send Norway B2B electronic invoices over the Peppol network in Peppol BIS 3.0 / EHF (EN 16931) format via Storecove, a certified Peppol Access Point. It builds the structured invoice, computes the Norwegian VAT (MVA) breakdown, and delivers it under the merchant's own Storecove account. Stateless, bring-your-own credentials, never stores anything.

Why now — the mandate (elektronisk faktura EHF)

Norway is moving to mandatory structured e-invoicing over Peppol BIS 3.0 / EHF for domestic B2B: the parliament (Stortinget) has adopted the reform and the sending obligation applies from 2027-01-01. EHF (Elektronisk Handelsformat) is Peppol BIS Billing 3.0 based. Paper and plain-PDF invoices no longer satisfy the B2B obligation.

Quick start

{
  "mcpServers": {
    "norway-invoice": {
      "type": "http",
      "url": "https://inv-no.wishpool.app/mcp",
      "headers": {
        "x-storecove-key": "your-storecove-api-key"
      }
    }
  }
}

Sign up at storecove.com — the merchant is the Peppol Access Point account holder. Request a free 30-day sandbox account from Storecove for a test key (sandbox does not need production onboarding). Create your sender under Senders to get the legalEntityId you pass as seller_legal_entity_id. Sandbox vs production is determined by the account your key belongs to — the base URL is the same. Authentication is HTTP Bearer with your key. Your key stays with you and travels per-request; this server never stores it.

Tools

Amounts are in NOK. Norwegian VAT (MVA) rates: 25 (standard), 15 (food/groceries), 12 (transport/accommodation and other low-rate services), 0 (zero-rated/exempt/reverse charge). Parties identified by Norwegian VAT (NO<9 digits>MVA) and/or organisasjonsnummer (9 digits); Peppol routing scheme 0192.

No cancel over Peppol — to reverse an invoice you issue a credit note (a new invoice). create_invoice needs seller_legal_entity_id (your Storecove sender id). Owner policy guardrails ride optional headers (x-agentpay-max-amount, x-agentpay-approval-above, x-agentpay-allowed-tools) — set by the human owner in client config; the agent cannot relax them.

VAT math (deterministic)

Per line amountExcludingVat = round2(quantity × unit_price); grouped by (rate, category) into taxSubtotals (taxableAmount, taxAmount = round2(taxable × rate / 100)); gross amountIncludingVat = taxable + tax. Examples:

• 100 + 50 both @25% → taxable 150.00 / vat 37.50 / total 187.50

• 200 @25% + 100 @15% → taxable 300.00 / vat 65.00 (50 + 15) / total 365.00

• 2×50 @25% + 3×10 @15% + 1×40 @12% + 1×25 @0% → taxable 195.00 / vat 34.30 (25 + 4.50 + 4.80 + 0) / total 229.30

• rounding: 33.33 @25% → 33.33 × 0.25 = 8.3325 → vat 8.33 / total 41.66

Endpoints wrapped (Storecove REST)

• Base: https://api.storecove.com/api/v2 (single base URL; auth = HTTP Bearer with your API key)

• Send: POST /document_submissions — JSON { legalEntityId, routing, document:{ documentType:"invoice", invoice:{…} } } → { guid }

• Evidence: GET /document_submissions/{guid}/evidence — proof of what was sent + Peppol delivery status

• Discovery: POST /discovery/receives — JSON { documentTypes, network, metaScheme, scheme, identifier } → { code:"OK", email }

• Verified probe: a fake Bearer key really hits api.storecove.com/api/v2 → 403 {"errors":[{"source":"generic","details":"Not Authorized"}]} (endpoint alive; BYO = the merchant's own key validates).

Safety

Pure stateless translation layer over the Storecove REST API. Storecove is the certified Peppol Access Point under the merchant's own account; this service never signs, never onboards, and never stores anything. The API key travels per-request in a header, and funds are never touched — this issues tax invoices, it does not move money. Privacy policy.

Sister servers

Local invoices, one family: Denmark Peppol/NemHandel (inv-dk) · Belgium Peppol BIS (inv-be) · Italy FatturaPA (inv-it) · Malaysia MyInvois (inv-my) · Mexico CFDI (inv-mx) · Brazil NF-e (inv-br) · India GST (inv-in). Storecove also covers the Nordics, the Netherlands and Luxembourg on Peppol — those sister countries replicate this exact server. Local logistics: logi.wishpool.app. Local payments in 81 countries: mcp.wishpool.app.
