Public developer pilot

Jithox E-Invoice

Jithox E-Invoice is a public remote MCP server that answers one question for AI agents working on EU B2B e-invoicing: is this invoice ready — and if not, why not. VAT checks, live VIES verification, Peppol discovery, invoice validation and composed readiness, with evidence and provenance attached. Read-only by design.

Connection facts

Endpoint
https://mcp.jithox.com/mcp
Transport
Streamable HTTP
Authentication
OAuth 2.1 with Dynamic Client Registration and PKCE (S256) — every call is authenticated and scoped
Access model
Read-only. No tool on this server sends, writes or transmits anything.

Exactly five tools, all read-only

  • validate_vat_number

    VAT number format validation (structure, country rules)

  • verify_vat_vies

    Live VIES verification of EU VAT numbers

  • lookup_peppol_participant

    Peppol SML/SMP participant discovery

  • validate_invoice

    Invoice validation against e-invoicing rules

  • get_einvoice_readiness

    Composed e-invoice readiness with blocking reasons, warnings and next actions

Boundaries — what this MCP will not do

  • There is no send capability: send_peppol_invoice does not exist here, and Jithox does not send invoices through this MCP.
  • No compliance guarantee. No fiscal or legal guarantee — validation output is technical evidence, not advice.
  • A provider outage stays an outage: when VIES, SML/SMP or another upstream registry cannot answer, you get that fact — it is never converted into invalid or not_found.
  • Signed receipts on results; evidence and provenance included.

Explicit decision states

Results carry explicit, machine-readable states — such as not_found, not_configured, needs_review, unavailable — so an agent can tell “nothing was found”, “this needs a human” and “the registry was down” apart without guessing.

Status and access

Last verified: 18 July 2026.

  • The endpoint is live and in a developer pilot, operator-tested.
  • A client-neutral acceptance evaluation with external MCP clients is still in progress; no desktop or IDE GUI client is proven end-to-end yet.
  • Not yet independently penetration-tested.
  • No paying external developers yet, no independent reviews and no customer numbers — we publish none rather than invent them.
  • Pilot pricing is €39 for 30 days: one developer, 10,000 accepted executions, no overage and no automatic renewal. While the acceptance evaluation runs, this is not general availability — start at mcp.jithox.com or write to us, and we onboard pilot developers deliberately.

Clients and compatibility

Any MCP client that speaks Streamable HTTP and OAuth 2.1 with Dynamic Client Registration (PKCE S256) should be able to connect. Client-by-client status is listed honestly on the MCP site instead of claiming universal support.

Privacy, security and support

  • The tools process the business identifiers you submit (VAT numbers, Peppol participant IDs, invoice documents) to answer that call — see the privacy policy.
  • Security mechanisms and their honest limits are documented on the trust page — including that internal testing is not an independent penetration test.
  • Support: info.jithox@gmail.com — a human reads every message.
