What is the Eleata E MCP server?

Validate EU e-invoices (Peppol, XRechnung, Factur-X, UBL, CII) and explain error codes. Exposed over MCP by the eleata e mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

What it actually does

Validate EU electronic invoices and explain validation error codes directly from your AI coding agent (Claude, Cursor, Copilot, …). It wraps the hosted eleata validation API plus a bundled offline error-code reference.

Its toolset

Everything the assistant can do here goes through one of these:

  • validate_einvoice — Validate one invoice (Peppol BIS 3.0, EN 16931 UBL/CII, XRechnung 3.0.x, Factur-X/ZUGFeRD, UBL, CII). Returns valid/invalid + each rule id
  • list_formats — List the formats eleata validates today + roadmap
  • explain_error_code — Explain one error code (e.g. 00400, BR-DE-21) in plain English, with the fix. Works offline

Configuration

You will need one environment variable: EINVOICE_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Adding it to your client

Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.

When to reach for it

Among the payments and commerce options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Eleata E's toolset — validate_einvoice, list_formats, explain_error_code — is a fair guide to whether it matches your workflow. It is maintained by hernaninverso; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against Eleata E's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Caveats

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the eleata e mcp server does with a few real requests.

Frequently asked questions

It connects Eleata E to MCP-compatible AI assistants such as Claude and Cursor, exposing 3 tools (validate_einvoice, list_formats, explain_error_code) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Eleata E directly.
