## MCP tools (3)

### `validate_einvoice` (~242 tokens)

Validate an EU electronic invoice against the official Schematron rules (Peppol BIS 3.0, EN 16931 UBL/CII, XRechnung 3.0.x, Factur-X/ZUGFeRD, UBL, CII). Returns whether it is valid and, for each violation, the rule id, a plain-English explanation and a suggested fix. Use this before a developer ships or transmits an invoice so a rejection (an SdI scarto, a Chorus Pro refusal, a KSeF error) is caught early. Requires EINVOICE_API_KEY (a free key from https://eleata.io/signup/).

Input parameters:

- `content` (string, required): The invoice to validate. For XML formats, the raw XML text. For a Factur-X / ZUGFeRD PDF, the base64-encoded PDF bytes (set is_pdf=true).
- `format` (string): Format hint. Default: auto (the server sniffs XML vs PDF and the profile).
- `is_pdf` (boolean): Set true if `content` is a base64-encoded PDF (Factur-X/ZUGFeRD). Default false.

### `list_formats` (~45 tokens)

List the EU e-invoice formats eleata can validate today, plus what is on the roadmap (e.g. FatturaPA, KSeF). No API key required.

### `explain_error_code` (~105 tokens)

Explain a single e-invoice validation error code (e.g. a FatturaPA SdI control like 00400, or an XRechnung rule like BR-DE-21) in plain English, with the suggested fix and an example. Works offline; no API key required.

Input parameters:

- `rule_id` (string, required): The rule id / error code, e.g. '00400', 'BR-DE-21', 'PEPPOL-EN16931-R053'.
